-Once you have finished installing devkitARM and devkitA64, simply clone the Atmosphère repo, change to it and run `make`.

 # Changelog
+## 0.10.1
++ A bug was fixed that caused memory reallocation to the system pool to work improperly on firmware 5.0.0 and above.
+  + Atmosphere was always trying to deallocate memory away from the applet pool and towards the system pool.
+    + The intent of this is to facilitate running more custom sysmodules/atmosphere binaries.
+  + However, while memory was always successfully taken away from the applet pool, on 5.0.0+ granting it to the system pool did not work for technical reasons.
+    + If you are interested in the technical details, talk to SciresM.
+  + This has now been fixed by adding new kernel patches, and memory is correctly granted to the system pool as intended.
++ Atmosphere's library system has been overhauled:
+  + libstratosphere's repository has been rebranded, more generally, to "Atmosphere-libs".
+    + In addition to libstratosphere, a new general library for not-stratosphere-specific code has been added.
+      + This is currently named `libvapours`.
+    + In the future, kernel functionality will be available as `libmesosphere`.
+  + The build system for stratosphere system modules has been similarly overhauled.
++ A number of other bugs were fixed, including:
+  + A bug was fixed that could cause memory corruption when redirecting certain Romfs content.
+  + A bug was fixed that could cause an infinite loop when redirecting certain Romfs content.
+  + A bug was fixed that could cause certain NROs to fail to load.
+    + This caused the latest version of Super Smash Bros to display "An error has occurred" on launch.
+  + A bug was fixed that caused input/output array sizes for certain circumstances to be calculated incorrectly.
+    + This caused cheats to fail to function properly.
+  + C++ exception code is now more thoroughly removed from stratosphere executables.
+    + This saves a minor amount of memory.
+  + A number of minor logic inversions were fixed in libstratosphere.
+    + These did not affect any code currently used by released Atmosphere binaries.
++ *Please note**: Because this update is releasing so soon after 0.10.0, the removal of the temporary hid-mitm has been postponed to 0.10.2.
+    + Please ensure your homebrew is updated.
++ Random number generation now uses TinyMT instead of XorShift.
++ General system stability improvements to enhance the user's experience.
+## 0.10.0
++ Support was added for 9.1.0
+  + **Please note**: The temporary hid-mitm added in Atmosphere 0.9.0 will be removed in Atmosphere 0.10.1.
+    + Please ensure your homebrew is updated.
++ The Stratosphere rewrite was completed.
+  + libstratosphere was rewritten as part of Stratosphere's refactor.
+    + Code responsible for providing and managing IPC services was greatly improved.
+      + The new code is significantly more accurate (it is bug-for-bug compatible with Nintendo's code), and significantly faster.
+  + ams.mitm was rewritten as part of Stratosphere's refactor.
+    + Saves redirected to the SD card are now separated for sysmmc vs emummc.
+    + **Please note**: If you find any bugs, please report them so they can be fixed.
++ Thanks to the rewrite, Atmosphere now uses significantly less memory.
+  + Roughly 10 additional megabytes are now available for custom system modules to use.
+  + This means you can potentially run more custom system modules simultaneously.
+    + If system modules are incompatible, please ask their authors to reduce their memory footprints.
++ Atmosphere's configuration layout has had major changes.
+  + Configuration now lives inside /atmosphere/config/.
+  + Atmosphere code now knows what default values should be, and includes them in code.
+    + It is no longer an error if configuration inis are not present.
+  + Correspondingly, Atmosphere no longer distributes default configuration inis.
+    + Templates are provided in /atmosphere/config_templates.
+  + loader.ini was renamed to override_config.ini.
+  + This fixes the longstanding problem that atmosphere updates overwrote user configuration when extracted.
++ Atmosphere's process override layout was changed.
+  + Atmosphere now uses the /atmosphere/contents directory, instead of /atmosphere/titles.
+    + This goes along with a refactoring to remove all reference to "title id" from code, as Nintendo does not use the term.
+  + To make this transition easier, a temporary functionality has been added that migrates folders to the new directory.
+    + When booting into 0.10.0, Atmosphere will rename /atmosphere/titles/`<program id>` to /atmosphere/contents/`<program id>`.
+      + This functionality may or may not be removed in some future update.
+    + This should solve any transition difficulties for the typical user.
+    + Please make sure that any future mods you install extract to the correct directory.
++ Support for configuring override keys for hbl was improved.
+  + The key used to override applications versus a specific program can now be different.
+    + The key to override a specific program can be managed via override_key.
+    + The key to override any app can be managed via override_any_app_key.
+  + Default override behavior was changed.
+    + By default, atmosphere will now override the album applet with hbl unless R is held.
+    + By default, atmosphere will now override any application with hbl only if R is held.
++ The default amount of applet memory reserved has been slightly increased.
+  + This allows the profile selector applet to work by default in applet mode.
++ The way process override status is captured was changed.
+  + Process override keys are now captured exactly once, when the process is created.
+    + This fixes the longstanding issue where letting go of the override button partway into the process launch could cause problems.
+  + The Mitm API was changed to pass around override status.
+    + Mitm services now know what keys were held when the client was created, as well as whether the client is HBL/should override contents.
+  + An extension was added to pm:info to allow querying a process's override status.
++ Thanks to process override capture improvements, hbl html behavior has been greatly improved.
+  + Web applets launched by hbl will now always see the /atmosphere/hbl_html filesystem
++ Support was added to exosphere for enabling usermode access to the PMU registers.
+  + This can be controlled via exosphere!enable_user_pmu_access in BCT.ini.
++ An enormous number of minor bugs were fixed.
+  + dmnt's cheat VM had a fix for an inversion in opcode behavior.
+  + An issue was fixed in fs.mitm's management of domain object IDs that could lead to system corruption in rare cases.
+  + The Mitm API no longer silently fails when attempting to handle commands passing C descriptors.
+    + On previous atmosphere versions, certain commands to FS would silently fail due to this...
+      + No users reported any visible errors, but it was definitely a problem behind the scenes.
+    + These commands are now handled correctly.
+  + Atmosphere can now display a fatal error screen significantly earlier in the boot process, if things go wrong early on.
+  + The temporary hid mitm will no longer sometimes cause games to fail to detect input.
+  + Mitm Domain object ID management no longer desynchronizes from the host process.
+  + An issue was fixed that could cause service acquisition to hang forever if certain sm commands were called in a precise order.
+  + An off-by-one was fixed that could cause memory corruption in server memory management.
+  + ... and too many more bugs fixed to reasonably list them all :)
++ General system stability improvements to enhance the user's experience.
+## 0.9.4
++ Support was added for 9.0.0.
+  + **Please note**: 9.0.0 made a number of changes that may cause some issues with homebrew. Details:
+  + 9.0.0 changed HID in a way that causes libnx to be unable to detect button input.
+    + Homebrew should be recompiled with newest libnx to fix this.
+    + Atmosphere now provides a temporary hid-mitm that will cause homebrew to continue to work as expected.
+      + This mitm will be removed in a future Atmosphere revision once homebrew has been updated, to allow users to use a custom hid mitm again if they desire.
+  + 9.0.0 introduced an dependency in FS on the USB system module in order to launch the SD card.
+    + This means the USB system module must now be launched before the SD card is initialized.
+    + Correspondingly, the USB system module can no longer be IPS patched, and its settings cannot be reliably mitm'd.
+    + We know this is frustrating, so we'll be looking into whether there is some way of addressing this in the future.
++ An off-by-one error was fixed in `boot` system module's pinmux initialization.
+  + This could theoretically have caused issues with HdmiCec communication.
+  + No users reported issues, so it's unclear if this was a problem in practice.
++ A bug was fixed that could cause webapplet launching homebrew to improperly set the accessible url whitelist.
++ BIS key generation has been fixed for newer hardware.
+  + Newer hardware uses new, per-firmware device key to generate BIS keys instead of the first device key, so previously the wrong keys were generated as backup.
+  + This only affects units manufactured after ~5.0.0.
++ General system stability improvements to enhance the user's experience.
+## 0.9.3
++ Thanks to hexkyz, fusee's boot sequence has been greatly optimized.
+  + Memory training is now managed by a separate binary (`fusee-mtc`, loaded by fusee-primary before fusee-secondary).
+  + Unnecessarily long splash screen display times were reduced.
+  + The end result is that Atmosphere now boots *significantly* faster. :)
+  + **Note:** This means fusee-primary must be updated for Atmosphere to boot successfully.
++ The version string was adjusted, and now informs users whether or not they are using emummc.
++ Atmosphere now automatically backs up the user's BIS keys on boot.
+  + This should prevent a user from corrupting nand without access to a copy of the keys needed to fix it.
+    + This is especially relevant on ipatched units, where the RCM vulnerability is not an option for addressing bricks.
++ The `pm` system module was rewritten as part of Stratosphere's ongoing refactor.
+  + Support was added for forward-declaring a mitm'd service before a custom user sysmodule is launched.
+    + This should help resolve dependency issues with service registration times.
+  + SM is now informed of every process's title id, including built-in system modules.
++ The `creport` system module was rewritten as part of Stratosphere's ongoing refactor.
+  + creport now dumps up to 0x100 of stack from each thread in the target process.
+  + A few bugs were fixed, including one that caused creport to incorrectly dump process dying messages.
++ Defaults were added to `system_settings.ini` for controlling hbloader's memory usage in applet mode.
+  + These defaults reserve enough memory so that homebrew can launch swkbd while in applet mode.
++ The `fatal` system module was rewritten as part of Stratosphere's ongoing refactor.
+  + Incorrect display output ("2000-0000") has been fixed. Fatal will now correctly show 2162-0002 when this occurs.
+  + A longstanding bug in how fatal manages the displays has been fixed, and official display init behavior is now matched precisely.
++ General system stability improvements to enhance the user's experience.
+## 0.9.2
++ A number of emummc bugfixes were added (all thanks to @m4xw's hard work). The following is a summary of emummc changes:
+  + Support for file-based emummc instances was fixed.
+    + Please note: file-based emummc is still unoptimized, and so may be much slower than partition-based.
+    + This speed differential should hopefully be made better in a future emummc update.
+  + The way emummc handles power management was completely overhauled.
+    + Emummc now properly handles init/de-init, and now supports low voltage mode.
+    + Much better support for shutdown was added, which should assuage corruption/synchronization problems.
+    + This should also improve support for more types of SD cards.
+  + A bug was fixed that caused emummc to not work on lower system versions due to missing SVC access.
+  + **Please note**: The configuration entries used for emummc have been changed.
+    + `emummc_` prefixes have been removed, since they are superfluous given the `emummc` category they are under.
+    + As an example, `emummc!emummc_enabled` is now `emummc!enabled`.
+    + INI configurations made by @CTCaer's [tool](https://github.com/ctcaer/hekate/releases/latest) (which is the recommended way to manage emummc) should automatically work as expected/be corrected.
+      + **If you do not wish to use the above, you will need to manually correct your configuration file**.
+  + General system stability improvements to enhance the user's experience.
++ Stratosphere is currently in the process of being re-written/refactored.
+  + Stratosphere was my (SciresM's) first C++ project, ever -- the code written for it a year ago when I was learning C++ is/was of much lower quality than code written more recently.
+  + Code is thus being re-rwitten for clarity/stlye/to de-duplicate functionality, with much being moved into libstratosphere.
+  + Stratosphere will, after the rewrite, globally use the `sts::` namespace -- this should greatly enhancing libstratosphere's ability to provide functionality for system modules.
+  + The rewritten modules consistently have lower memory footprints, and should be easier to maintain going forwards.
+  + The `sm`, `boot`, `spl`, `ro`, and `loader` modules have been tackled so far.
++ General system stability improvements to enhance the user's experience.
+## 0.9.1
++ Support was added for 8.1.0.
++ Please note, emummc is still considered **beta/experimental** -- this is not the inevitable bugfix update for it, although some number of bugs have been fixed. :)
++ General system stability improvements to enhance the user's experience.
+## 0.9.0
++ Creport output was improved significantly.
+  + Thread names are now dumped on crash in addition to 0x100 of TLS from each thread.
+    + This significantly aids debugging efforts for crashes.
+  + Support was added for 32-bit stackframes, so reports can now be generated for 32-bit games.
++ `dmnt`'s Cheat VM was extended to add a new debug opcode.
++ With thanks to/collaboration with @m4xw and @CTCaer, support was added for redirecting NAND to the SD card (emummc).
+  + Please note, this support is very much **beta/experimental**.
+    + It is quite likely we have not identified all bugs -- those will be fixed as they are reported over the next few days/weeks.
+    + In addition, some niceties (e.g. having a separate Atmosphere folder per emummc instance) still need some thought put in before they can be implemented in a way that makes everyone happy.
+    + If you are not an advanced user, you may wish to think about waiting for the inevitable 0.9.1 bugfix update before using emummc as your default boot option.
+      + You may especially wish to consider waiting if you are using Atmosphere on a unit with the RCM bug patched.
+  + Emummc is managed by editing the emummc section of "emummc/emummc.ini".
+    + To enable emummc, set `emummc!emummc_enabled` = 1.
+  + Support is included for redirecting NAND to a partition on the SD card.
+    + This can be done by setting `emummc!emummc_sector` to the start sector of your partition (e.g., `emummc_sector = 0x1A010000`).
+  + Support is also included for redirecting NAND to a collection of loose files on the SD card.
+    + This can be done by setting `emummc!emummc_path` to the folder (with archive bit set) containing the NAND boot partitions' files "boot0" and "boot1", and the raw NAND image files "00", "01", "02", etc. (single "00" file with the whole NAND image requires exFAT mode while multipart NAND can be used in both exFAT and FAT32 modes).
+  + The `Nintendo` contents directory can be redirected arbitrarily.
+    + By default, it will be redirected to `emummc/Nintendo_XXXX`, where `XXXX` is the hexadecimal representation of the emummc's ID.
+      + The current emummc ID may be selected by changing `emummc!emummc_id` in emummc.ini.
+    + This can be set to any arbitrary directory by setting `emummc!emummc_nintendo_path`.
+  + To create a backup usable for emummc, users may use tools provided by the [hekate](https://github.com/CTCaer/hekate) project.
+  + If, when using emummc, you encounter a bug, *please be sure to report it* -- that's the only way we can fix it. :)
+## 0.8.10
++ A bug was fixed that could cause incorrect system memory allocation on 5.0.0.
+  + 5.0.0 should now correctly have an additional 12 MiB allocated for sysmodules.
++ Atmosphère features which check button presses now consider all controllers, isntead of just P1.
++ Support was added for configuring language/region on a per-game basis.
+  + This is managed by editing `atmosphere/titles/<title id>/config.ini` for the game.
+  + To edit title language, edit `override_config!override_language`.
+    + The languages supported are `ja`, `en-US`, `fr`, `de`, `it`, `es`, `zh-CN`, `ko`, `nl`, `pt`, `ru`, `zh-TW`, `en-GB`, `fr-CA`, `es-419`, `zh-Hans`, `zh-Hant`.
+  + To edit title region, edit `override_config!override_region`.
+    + The regions supported are `jpn`, `usa`, `eur`, `aus`, `chn`, `kor`, `twn`.
++ Atmosphère now provides a reimplementation of the `boot` system module.
+  + `boot` is responsible for performing hardware initialization, showing the Nintendo logo, and repairing NAND on system update failure.
+  + Atmosphère's `boot` implementation preserves AutoRCM during NAND repair.
+    + NAND repair occurs when an unexpected shutdown or error happens during a system update.
+    + This fixes a final edge case where AutoRCM might be removed by HOS, which could cause a user to burn fuses.
++ General system stability improvements to enhance the user's experience.
+## 0.8.9
++ A number of bugs were fixed, including:
+  + A data abort was fixed when mounting certain partitions on NAND.
+  + All Stratosphère system modules now only maintain a connection to `sm` when actively using it.
+    + This helps mitigate the scenario where sm hits the limit of 64 active connections and crashes.
+    + This sometimes caused crashes when custom non-Atmosphère sysmodules were active and the user played certain games (ex: Smash's Stage Builder).
+  + fatal now uses the 8.0.0 clkrst API, instead of silently failing to adjust clock rates on that firmware version.
+  + A wait loop is now performed when trying to get a session to `sm`, in the case where `sm:` is not yet registered.
+    + This fixes a race condition that could cause a failure to boot under certain circumstances.
+  + libstratosphere's handling of domain object closing has been improved.
+    + Previously, this code could cause crashes/extremely odd behavior (misinterpreting what object a service is) under certain circumstances.
++ An optional automatic reboot timer was added to fatal.
+  + By setting the system setting `atmosphere!fatal_auto_reboot_interval` to a non-zero u64 value, fatal can be made to automatically reboot after a certain number of milliseconds.
+  + If the setting is zero or not present, fatal will wait for user input as usual.
++ Atmosphère now provides a reimplementation of the `ro` system module.
+  + `ro` is responsible for loading dynamic libraries (NROs) on 3.0.0+.
+    + On 1.0.0-2.3.0, this is handled by `loader`.
+  + Atmosphere's `ro` provides this functionality (`ldr:ro`, `ro:dmnt`) on all firmware versions.
+  + An extension was implemented to provide support for applying IPS patches to NROs.
+    + All patches at paths like /atmosphere/nro_patches/<user-defined patch name>/<Hex Build-ID for NRO to patch>.ips will be applied, allowing for easy distribution of patches.
+    + Both the IPS and IPS32 formats are supported.
++ Atmosphère now provides a reimplementation of the `spl` system module.
+  + `spl` (Secure Platform Services) is responsible for cryptographic operations, including all communications with the secure monitor (exosphère).
+  + In the future, this may be used to provide extensions to the API for interacting with exosphère from userland.
++ General system stability improvements to enhance the user's experience.
+## 0.8.8
++ Support was added for firmware version 8.0.0.
++ Custom exception handlers were added to stratosphere modules.
+  + If a crash happens in a core atmosphere module now, instead of silently failing a reboot will occur to log the information to the SD card.
++ A bug was fixed in creport that caused games to hang when crashing under certain circumstances.
++ A bug was fixed that prevented maintenance mode from booting on 7.0.0+.
++ General system stability improvements to enhance the user's experience.
+## 0.8.7
++ A few bugs were fixed that could cause fatal to fail to show an error under certain circumstances.
++ A bug was fixed that caused an error when launching certain games (e.g. Hellblade: Senua's Sacrifice).
+  + Loader had support added in ams-0.8.4 for a new (7.0.0+) flag bit in NPDMs during process creation, but forgot to allow this bit to be set when validating the NPDM.
++ dmnt's cheat virtual machine received new instructions.
+  + These allow for saving, restoring, or clearing registers to a secondary bank, effectively doubling the number of values that can be stored.
++ SHA256 code has been swapped from linux code to libnx's new hw-accelerated cryptography API.
++ Extensions were added to smcGetInfo:
+  + A ConfigItem was added to detect whether the current unit has the RCM bug patched.
+  + A ConfigItem was added to retrieve the current Atmosphère build hash.
++ Exosphère now tells the kernel to enable user-mode exception handlers, which should allow for better crash reporting/detection from Atmosphère's modules in the future..
++ Opt-in support was added for redirecting game save files to directories on the SD card.
+  + Please note, this feature is **experimental**, and may cause problems. Please use at your own risk (and back up your saves before enabling it), as it still needs testing.
+  + This can be enabled by setting `atmosphere!fsmitm_redirect_saves_to_sd` to 1 in `system_settings.ini`.
++ General system stability improvements to enhance the user's experience.
+## 0.8.6
++ A number of bugs were fixed, including:
+  + A case of inverted logic was fixed in fs.mitm which prevented the flags system from working correctly.
+  + Time service access was corrected in both creport/fatal.
+    + This fixes the timestamps used in fatal/crash report filenames.
+  + A coherency issue was fixed in exosphère's Security Engine driver.
+    + This fixes some instability issues encountered when overclocking the CPU.
+  + Loader now unmaps NROs correctly, when ldr:ro is used.
+    + This fixes a crash when repeatedly launching the web applet on < 3.0.0.
+  + Usage of hidKeysDown was corrected to hidKeysHeld in several modules.
+    + This fixes a rare issue where keypresses may have been incorrectly detected.
+  + An issue with code filesystem unmounting was fixed in loader.
+    + This issue could occasionally cause a fatal error 0x1015 to be thrown on boot.
+  + Two bugs were fixed in the implementations of dmnt's cheat virtual machine.
+    + These could cause cheats to work incorrectly under certain circumstances.
+  + PM now uses a static buffer instead of a dynamically allocated one during process launch.
+    + This fixes a memory exhaustion problem when building with gcc 8.3.0.
+  + A workaround for a deadlock bug in Horizon's kernel on >= 6.0.0 was added in dmnt.
+    + This prevents a system hang when booting certain titles with cheats enabled (ex: Mario Kart 8 Deluxe).
+  + set.mitm now reads the system firmware version directly from the system version archive, instead of calling into set:sys.
+    + This fixes compatibility with 1.0.0, which now successfully boots again.
++ dmnt's cheat virtual machine had some instruction set changes.
+  + A new opcode was added for beginning conditional blocks based on register contents.
+  + More addressing modes were added to the StoreRegisterToAddress opcode.
+  + These should allow for more complex cheats to be implemented.
++ A new system for saving the state of cheat toggles between game boots was added.
+  + Toggles are now saved to `atmosphere/titles/<title id>/cheats/toggles.txt` when either toggles were successfully loaded from that file or the system setting `atmosphere!dmnt_always_save_cheat_toggles` is non-zero.
+  + This removes the need for manually setting cheats from all-on or all-off to the desired state on each game boot.
++ The default behavior for loader's HBL support was changed.
+  + Instead of launching HBL when album is launched without R held, loader now launches HBL when album or any game is launched with R held.
+  + Loader will now override any app in addition to a specific title id when `hbl_config!override_any_app` is true in `loader.ini`.
+    + Accordingly, the `hbl_config!title_id=app` setting was deprecated. Support will be removed in Atmosphère 0.9.0.
++ First-class support was added to loader and fs.mitm for enabling homebrew to launch web applets.
+  + Loader will now cause the "HtmlDocument" NCA path to resolve for whatever title HBL is taking over, even if it would not normally do so.
+  + fs.mitm will also now cause requests to mount the HtmlDocument content for HBL's title to open the `sdmc:/atmosphere/hbl_html` folder.
+    + By default, this just contains a URL whitelist.
++ General system stability improvements to enhance the user's experience.
+## 0.8.5
++ Support was added for overriding content on a per-title basis, separate from HBL override.
+  + This allows for using mods on the same title that one uses to launch HBL.
+  + By default, `!L` is used for title content override (this is configurable by editing `default_config!override_key` in `loader.ini`)
+  + This key combination can be set on a per-title basis by creating a `atmosphere/titles/<title id>/config.ini`, and editing `override_config!override_key`.
++ Content headers were added for the embedded files inside of fusee-secondary.
+  + This will allow non-fusee bootloaders (like `hekate`) to extract the components bundled inside release binaries.
+  + This should greatly simplify the update process in the future, for users who do not launch Atmosphère using fusee.
++ Support for cheat codes was added.
+  + These are handled by a new `dmnt` sysmodule, which will also reimplement Nintendo's Debug Monitor in the future.
+  + Cheat codes can be enabled/disabled at application launch via a per-title key combination.
+    + For details, please see the [cheat loading documentation](https://github.com/Atmosphere-NX/Atmosphere/blob/master/docs/cheats.md#cheat-loating-process).
+  + Cheat codes are fully backwards compatible with the pre-existing format, although a number of bugs have been fixed and some new features have been added.
+    + For details, please see [the compatibility documentation](https://github.com/Atmosphere-NX/Atmosphere/blob/master/docs/cheats.md#cheat-code-compatibility).
+  + An HIPC service API was added (`dmnt:cht`), that will allow user homebrew to interface with and control Atmosphère's cheat manager.
+    + Please see [the relevant documentation](https://github.com/Atmosphere-NX/Atmosphere/blob/master/docs/modules/dmnt.md).
+    + Full client code can be found in [libstratosphere](https://github.com/Atmosphere-NX/libstratosphere/blob/master/include/stratosphere/services/dmntcht.h).
+    + Users interested in interfacing should see [EdiZon](https://github.com/WerWolv/EdiZon), which should have support for interfacing with Atmosphère's API shortly after 0.8.5 releases.
++ A bug was fixed that would cause Atmosphère's fatal screen to not show on 1.0.0-2.3.0.
++ A bug was fixed that caused Atmosphère's automatic ProdInfo backups to be corrupt.
++ General system stability improvements to enhance the user's experience.
+## 0.8.4
++ Support for 7.0.0/7.0.1 was added.
+  + This is facilitated through a new payload, `sept`, which can be signed, encrypted, and then loaded by Nintendo's TSEC firmware.
+  + `sept` will derive the keys needed to boot new firmware, and then load `sept/payload.bin` off the SD card and jump to it.
++ Recognition of applications for override/mitm has been improved.
+  + Nintendo's official Title ID range (`0x0100000000000000`-`0x01FFFFFFFFFFFFFF`) is now enforced.
++ A deadlock condition was fixed involving libstratosphere mitm sysmodules.
++ Kernel patches for JIT support were added (Thanks, @m4xw!).
+  + These loosen restrictions on caller process in svcControlCodeMemory.
++ `set.mitm` and `fs.mitm` were merged into a single `ams_mitm` sysmodule.
+  + This saves a process ID, allowing users to run one additional process up to the 0x40 process limit.
++ A `bpc.mitm` component was added, performing custom behavior on shutdown/reboot requests from `am` or applications.
+  + Performing a reboot from the reboot menu now reboots to atmosphere. This can be configured via `system_settings.ini`.
+  + Performing a shutdown from the reboot menu now works properly with AutoRCM, and does a real shutdown.
++ General system stability improvements to enhance the user's experience.
+## 0.8.3
++ A custom warmboot firmware was implemented, which does not perform anti-downgrade fuse checks.
+  + This fixes sleep mode when using a downgraded NAND.
+  + This also removes Atmosphère's final dependency on Nintendo's encrypted PK11 binary; all components are now re-implemented.
++ The ExternalContentSource API was changed to not clear on failure.
++ Content override now supports an "app" setting, that causes all applications to be overridden with HBL instead of a specific title.
+  + Note: because override keys are system-wide, using this setting will prevent using mods in games (as every game will be HBL).
++ A bug was fixed causing incorrect fatal-error output when svcBreak was called on 5.0.0+.
++ An extension was added to set.mitm to support customization of system settings.
+  + These are controlled by `atmosphere/system_settings.ini`, see [here](https://github.com/Atmosphere-NX/Atmosphere/blob/master/docs/modules/set_mitm.md) for documentation.
++ An extension was added to sm, adding a new `sm:dmnt` service.
+  + This can be used by a debug monitor in order to debug the registration state of various other services.
++ A bug was fixed in the MitM API that could sometimes cause a system hang during boot.
++ A change was made to the MitM API: in cases where sm would have returned 0xE15 when installing a mitm service, it now defers the result (following GetService semantics).
++ Support for booting into maintenance mode by holding +/- was added to PM.
++ An extension was added to exosphere, adding a custom SMC that allows for DMA to IRAM.
++ In addition, smcGetConfig was extended to reboot to a payload in IRAM at 0x40010000 when ConfigItem 65001 is set to 2.
+  + Fatal will now use this to reboot to sdmc:/atmosphere/reboot_payload.bin if present, when a vol button is pressed.
+  + An example homebrew ("reboot_to_payload") was also written and is now included with Atmosphère.
++ General system stability improvements to enhance the user's experience.
+## 0.8.2
++ A number of bugs were fixed causing users to sometimes see `Key Derivation Failed!`.
+  + KFUSE clock enable timings have been adjusted to allow time to stabilize before TSEC is granted access.
+  + A race condition was fixed that could cause wrong key data to be used on 6.2.0
+  + The TSEC firmware is now retried on failure, fixing a failure affecting ~1/50 boots on 6.2.0.
++ A bug was fixed causing some modules to not work on firmware 1.0.0.
++ A bug was fixed causing sleep mode to not work with debugmode enabled.
+  + As a result, debugmode is now enabled in the default BCT.ini.
++ General system stability improvements to enhance the user's experience.
+## 0.8.1
++ A bug was fixed causing users to see `Failed to enable SMMU!` if fusee had previously rebooted.
+  + This message will still occur sporadically if fusee is not launched from coldboot, but it can never happen twice in a row.
++ A race condition was fixed in Atmosphere `bis_protect` functionality that could cause NS to be able to overwrite BCT public keys.
+  + This sometimes broke AutoRCM protection, the current fix has been tested on hardware and verified to work.
++ Support was added for enabling `debugmode` based on the `exosphere` section of `BCT.ini`:
+  + Setting `debugmode = 1` will cause exosphere to tell the kernel that debugmode is active.
+  + Setting `debugmode_user = 1` will cause exosphere to tell userland that debugmode is active.
+  + These are completely independent of one another, allowing fine control of system behavior.
++ Support was added for `nogc` functionality; thanks to @rajkosto for the patches.
+  + By default, `nogc` patches will automatically apply if the user is booting into 4.0.0+ with fuses from <= 3.0.2.
+  + Users can override this functionality via the `nogc` entry in the `stratosphere` section of `BCT.ini`:
+    + Setting `nogc = 1` will force enable `nogc` patches.
+    + Setting `nogc = 0` will force disable `nogc` patches.
+  + If patches are enabled but not found for the booting system, a fatal error will be thrown.
+    + This should prevent running FS without `nogc` patches after updating to an unsupported system version.
++ An extension was added to `exosphere` allowing userland applications to cause the system to reboot into RCM:
+  + This is done by calling smcSetConfig(id=65001, value=<nonzero>); user homebrew can use splSetConfig for this.
++ On fatal error, the user can now choose to perform a standard reboot via the power button, or a reboot into RCM via either volume button.
++ A custom message was added to `fatal` for when an Atmosphère API version mismatch is detected (2495-1623).
++ General system stability improvements to enhance the user's experience.
+## 0.8.0
++ A custom `fatal` system module was added.
+  + This re-implements and extends Nintendo's fatal module, with the following features:
+    + Atmosphère's `fatal` does not create error reports.
+    + Atmosphère's `fatal` draws a custom error screen, showing registers and a backtrace.
+    + Atmosphère's `fatal` attempts to gather debugging info for all crashes, and not just ones that include info.
+    + Atmosphère's `fatal` will attempt saving reports to the SD, if a crash report was not generated by `creport`.
++ Title flag handling was changed to prevent folder clutter.
+  + Instead of living in `atmosphere/titles/<tid>/%s.flag`, flags are now located in `atmosphere/titles/<tid>/flags/%s.flag`
+    + The old format will continue to be supported for some time, but is deprecated.
+  + Flags can now be applied to HBL by placing them at `atmosphere/flags/hbl_%s.flag`.
++ Changes were made to the mitm API, greatly improving caller semantics.
+  + `sm` now informs mitm services of a new session's process id, enabling custom handling based on title id/process id.
++ smhax is no longer enabled, because it is no longer needed and breaks significant functionality.
+  + Users with updated HBL/homebrew should see no observable differences due to this change.
++ Functionality was added implementing basic protections for NAND from userland homebrew:
+  + BOOT0 now has write protection for the BCT public key and keyblob regions.
+    + The `ns` sysmodule is no longer allowed to write the BCT public keys; all other processes can.
+      + This should prevent system updates from removing AutoRCM.
+    + No processes should be allowed to write to the keyblob region.
+  + By default, BIS partitions other than BOOT0 are now read-only, and CAL0 is neither readable nor writable.
+    + Adding a `bis_write` flag for a title will allow it to write to BIS.
+    + Adding a `cal_read` flag for a title will allow it to read CAL0.
+  + An automatic backup is now made of CAL0 on boot.
+    + `fs.mitm` maintains a file handle to this backup, so userland software cannot read it.
+  + To facilitate this, `fs.mitm` now mitms all sessions for non-system modules; content overriding has been made separate from service interception.
+  + Please note: these protections are basic, and sufficiently malicious homebrew ++can defeat them++.
+    + Please be careful to only run homebrew software from sources that you trust.
++ A bug involving HDCP titles crashing on newer firmwares was fixed.
++ Support was added for system version 6.2.0; our thanks to @motezazer for his invaluable help.
+  + By default, new keys will automatically be derived without user input.
+  + Support is also present for loading new keys from `atmosphere/prod.keys` or `atmosphere/dev.keys`
++ General system stability improvements to enhance the user's experience.
+## 0.7.5
++ DRAM training was added to fusee-secondary, courtesy @hexkyz.
+  + This greatly improves the speed of memory accesses during boot, resulting in a boot time that is ~200-400% faster.
++ creport has had its code region detection improved.
+  + Instead of only checking one of the crashing thread's PC/LR for code region presence, creport now checks both + every address in the stacktrace. This is also now done for every thread.
+    + This matches the improvement Nintendo added to official creport in 6.1.0.
+  + The code region detection heuristic was further improved by checking whether an address points to .rodata or .rwdata, instead of just .text.
+  + This means that a crash appears in a loaded NRO (or otherwise discontiguous) code region, creport will be able to detect all active code regions, and not just that one.
+## 0.7.4
++ [libstratosphere](https://github.com/Atmosphere-NX/libstratosphere) has been completely refactored/rewritten, and split into its own, separate submodule.
+  + While this is mostly "under the hood" for end-users, the refactor is faster (improving both boot-time and runtime performance), more accurate (many of the internal IPC structures are now bug-for-bug compatible with Nintendo's implementations), and significantly more stable (it fixes a large number of bugs present in the old library).
+  + The refactored API is significantly cleaner and easier to write system module code for, which should improve/speed up development of stratosphere.
+  + Developers looking to write their own custom system modules for the Switch can now easily include libstratosphere as a submodule in their projects.
++ Loader was extended to add a new generic way to redirect content (ExternalContentSources), courtesy @misson20000:
+  + A new command was added to ldr:shel, taking in a tid to redirect and returning a session handle.
+  + When the requested TID is loading, Loader will query the handle as though it were an IFileSystem.
+    + This allows clients to generically define their own filesystems, and override content with them in loader.
++ fs.mitm has gotten several optimizations that should improve its performance and stability:
+  + RomFS redirection now only occurs when there is content to redirect, even if the title is being mitm'd elsewhere.
+  + A cache is now maintained of the active data storage, if any, for all opened title IDs. This means if two processes both try to open the same archive, fs.mitm won't duplicate any of its work.
+  + RomFS metadata is now cached to the SD card on build instead of being persisted in memory -- this greatly reduces memory footprint and allows fs.mitm to redirect more titles simultaneously than before.
++ A number of bugs were fixed, including:
+  + A resource leak was fixed in process creation. This fixes crashes that occur when a large number (>32) games have been launched since the last reboot.
+  + fs.mitm no longer errors when receiving a zero-sized buffer. This fixes crashes in some games, including The Messenger.
+  + Multi-threaded server semantics should no longer cause deadlocks in certain circumstances. This fixes crashes in some games, including NES Classics.
+  + PM now only gives full FS permissions to the active KIPs. This fixes a potential crash where new processes might be unable to be registered with FS.
++ The `make dist` target now includes the branch in the generated zip name.
++ General system stability improvements to enhance the user's experience.
+## 0.7.3
++ Loader and fs.mitm now try to reload loader.ini before reading it. This allows for changing the override button combination/HBL title id at runtime.
++ Added a MitM between set:sys and qlaunch, used to override the system version string displayed in system settings.
+  + The displayed system version will now display `<Actual version> (AMS <x>.<y>.<z>)`.
++ General system stability improvements to enhance the user's experience.
 ## 0.7.2
 + Fixed a bug in fs.mitm's LayeredFS read implementation that caused some games to crash when trying to read files.
 + Fixed a bug affecting 1.0.0 that caused games to crash with fatal error 2001-0106 on boot.
 + Improved filenames output by the make dist target.
 + General system stability improvements to enhance the user's experience.
+
 ## 0.7.1
 + Fixed a bug preventing consoles on 4.0.0-4.1.0 from going to sleep and waking back up.
 + Fixed a bug preventing consoles on < 4.0.0 from booting without specific KIPs on the SD card.
 + An API was added to Atmosphère's Service Manager for deferring acquisition of all handles for specific services until after early initialization is completed.
 + General system stability improvements to enhance the user's experience.

+# Cheats
+Atmosphère supports Action-Replay style cheat codes, with cheats loaded off of the SD card.
+
+## Cheat Loading Process
+By default, Atmosphère will do the following when deciding whether to attach to a new application process:
+
++ Retrieve information about the new application process from `pm` and `loader`.
++ Check whether a user-defined key combination is held, and stop if not.
+  + This defaults to "L is not held", and can be configured the same way as `fs.mitm` override keys.
+  + The ini key to configure this is `cheat_enable_key`.
++ Check whether the process is a real application, and stop if not.
+  + This guards against applying cheat codes to the homebrew loader.
++ Attempt to load cheats from `atmosphere/titles/<title_id>/cheats/<build_id>.txt`, where `build_id` is the hexadecimal representation of the first 8 bytes of the application's main executable's build id.
+  + If no cheats are found, then the cheat manager will stop.
++ Open a kernel debug session for the new application process.
++ Signal to a system event that a new cheat process has been attached to.
+
+This behavior ensures that cheat codes are only loaded when the user would want them to.
+
+In cases where dmnt has not activated the cheat manager, but the user wants to make it do so anyway, the cheat manager's service API provides a `ForceOpenCheatProcess` command that homebrew can use. This command will cause the cheat manager to try to force itself to attach to the process.
+
+By default, all cheat codes listed in the loaded .txt file will be toggled on. This is configurable by the user, and the default can be set to toggled off by editing the `atmosphere!dmnt_cheats_enabled_by_default` entry to 0 instead of 1.
+
+Users may use homebrew programs to toggle cheats on and off at runtime via the cheat manager's service API.
+
+## Cheat Code Compatibility
+
+Atmosphère manages cheat code through the execution of a small, custom virtual machine. Care has been taken to ensure that Atmosphère's cheat code format is fully backwards compatible with the pre-existing cheat code format, though new features have been added and bugs in the pre-existing cheat code applier have been fixed. Here is a short summary of the changes from the pre-existing format:
+
++ A number of bugs were fixed in the processing of conditional instructions.
+  + The pre-existing implementation was fundamentally broken, and checked for the wrong value when detecting the end of a conditional block.
+  + The pre-existing implementation also did not properly decode instructions, and instead linearly scanned for the terminator value. This caused problems if an instruction happened to encode a terminator inside its immediate values.
+  + The pre-existing implementation did not bounds check, and thus certain conditional cheat codes could cause it to read out-of-bounds memory, and potentially crash due to a data abort.
++ Support was added for nesting conditional blocks.
++ An instruction was added to perform much more complex arbitrary arithmetic on two registers.
++ An instruction was added to allow writing the contents of register to a memory address specified by another register.
++ The pre-existing implementation did not correctly synchronize with the application process, and thus would cause heavy lag under certain circumstances (especially around loading screens). This has been fixed in Atmosphère's implementation.
+
+## Cheat Code Format

+In addition to the functionality provided by Nintendo's debug monitor, Atmosphère's dmnt has an extension for providing cheat code functionality. A HIPC Service API is provided for interacting with the cheat code manager, through the service `dmnt:cht`.
+
+Those looking for more information on the cheat code functionality may wish to read `cheats.md`.
+
+The SwIPC definition for `dmnt:cht` follows.

 Atmosphère can use the loader module in order to turn any game on your Switch's home menu into a launchpoint for the Homebrew Menu, rather than launching it through the album applet. This allows one to launch the Homebrew Menu with access to the ~3.2GB of RAM that the Switch reserves for games and applications, as opposed to the 442MB of RAM we are limited to when launching the Homebrew Menu from the album. This also means that it is no longer necessary to install homebrew as `.nsp` files on your Switch so long as you are using this method, as the only reason to do so is to allow the homebrew to access all of the Switch's available memory.
 
-In order to setup this method you will need the latest release of [hbmenu](https://github.com/switchbrew/nx-hbmenu/releases), and the latest release of [hbloader](https://github.com/switchbrew/nx-hbloader/releases). Place `hbmenu.nro` on the root of your Switch's SD Card, and place `hbl.nsp` in the atmosphere folder. From there, simply configure `loader.ini` in the atmosphere folder by replacing the Title ID in the ini (hbl_tid) (it is the Title ID for the album by default) with the Title ID of whatever game you wish to use to launch the Homebrew Menu. A list of Title IDs for Switch Games can be found [here](https://switchbrew.org/wiki/Title_list/Games). Afterwards you may reinsert your SD Card into your Switch and boot into Atmosphère as you normally would. You should now be able to boot into the Homebrew Menu by launching your designated game of choice.

Place `hbmenu.nro` on the root of your Switch's SD Card, and place `hbl.nsp` in the atmosphere folder. From there, simply launch any title while holding the button specified in `loader.ini`.
+
+In addition, loader has extensions to enable homebrew to launch web applets. This normally requires the application launching the applet have HTML Manual content inside an installed NCA; Atmosphère's loader will automatically ensure that the commands used to check this succeed, and will (in tandem with `fs.mitm`) redirect the relevant filesystem to the `sdmc:/atmosphere/hbl_html/` subdirectory.
 
 ### Button Overrides
 
-By default `loader.ini` is configured to launch the Homebrew Menu when launching the game normally, and launching the game when selecting the game while holding down R. If you wish to change this, you can modify the override_key section of `loader.ini`. Placing an exclamation point in front of whatever button you wish to use will make it so that you will only launch the actual game while holding down that button, otherwise you will go into the Homebrew Menu. Removing the exclamation point will reverse this, meaning that you will boot into the Homebrew Menu only while holding down the assigned button when launching the game.
+By default `loader.ini` is configured to launch the Homebrew Menu when launching any game while holding down the override key (defaults to R). If you wish to change this, you can modify the override_key section of `loader.ini`. Alternatively, if you would like to only allow hbmenu on a specific app, configure `loader.ini` in the atmosphere folder by replacing the Title ID in the ini (title_id in the [hbl_config] section, it is the Title ID for the album by default) with the Title ID of whatever game you wish to use to launch the Homebrew Menu, and set override_any_app to false. A list of Title IDs for Switch Games can be found [here](https://switchbrew.org/wiki/Title_list/Games).
 
-For example, `override_key=!R` will run the game only while holding down R when launching it, otherwise it will boot into the Homebrew Menu. `override_key=R` will only boot into the Homebrew Menu while holding down R when launching the game, otherwise it will launch the game as normal.
+To invert the behaviour of the override key, place an exclamation point in front of whatever button you wish to use. It will launch the actual game while holding down that button, instead of going into the Homebrew Menu. For example, `override_key=!R` will run the game only while holding down R when launching it, otherwise it will boot into the Homebrew Menu. Afterwards you may reinsert your SD Card into your Switch and boot into Atmosphère as you normally would. You should now be able to boot into the Homebrew Menu by launching your designated title of choice.

 ### SM MITM Integration
 
 When the Stratosphere implementation of loader creates a new process, it notifies [sm](sm.md) through the `AtmosphereAssociatePidTidForMitm` command to notify any MITM services of new processes' identities.
+
+### IPC: AtmosphereSetExternalContentSource and AtmosphereClearExternalContentSource
+
+Two additional commands are added to the [`ldr:shel`](https://reswitched.github.io/SwIPC/ifaces.html#nn::ro::detail::ILdrShellInterface) interface, called `AtmosphereSetExternalContentSource` and `AtmosphereClearExternalContentSource`.
+Their command IDs are `65000` and `65001` on all system firmware versions.
+
+`AtmosphereSetExternalContentSource` takes a `u64 tid` and returns a server-side session handle.
+The client is expected to implement the `IFileSystem` interface on the returned handle. The next
+time the title specified by the given title ID is launched, its ExeFS contents will be loaded from
+the custom `IFileSystem` instead of from SD card or original ExeFS. NSOs loaded from external
+content source may still be subject to exefs IPS patches. After the title is launched successfuly,
+the `IFileSystem` is closed and the external content source override is removed. If
+`AtmosphereSetExternalContentSource` is called on a title that already has an external content
+source set for it, the existing one will be removed and replaced with the new one. It is illegal to
+call `AtmosphereSetExternalContentSource` while the title is being launched.
+
+If title launching fails, the external content source remains registered. The
+`AtmosphereClearExternalContentSource` command can be used to clear an external content source if
+title launch fails.
+
+The `IFileSystem` only needs to implement `OpenFile` and `GetFileTimeStampRaw`. The paths received
+by the `IFileSystem`'s `OpenFile` command begin with slashes, as in `/main`, `/rtld`, and `/main.npdm`.
+A result code of 0x202 should be returned if the file does not exist. `GetFileTimeStampRaw` can just
+be a stub. The `IFile`s returned from `OpenFile` only need to implement `Read` and `GetSize`.
+
+The SwIPC definitions for the extension commands follow.
+```
+interface nn::ldr::detail::IShellInterface is ldr:shel {
+  ...
+  [65000] AtmosphereSetExternalContentSource(u64 tid) -> handle<copy, session_server> ifilesystem_handle;

+# set_mitm
+set_mitm is a sysmodule that enables intercepting requests to the system settings service.
+
+## Atmosphère Extensions
+
+set_mitm intercepts the `GetFirmwareVersion` command, if the requester is `qlaunch` or `maintenance`.\
+It modifies the `display_version` field of the returned system version, causing the version to display\
+in settings as `#.#.# (AMS #.#.#)`. This allows users to easily verify what version of Atmosphère they are running.
+
+set_mitm also intercepts the `GetSettingsItemValueSize` and `GetSettingsItemValue` commands for all requesters.\
+It does so in order to enable user configuration of system settings, which are parsed from `atmosphere/system_settings.ini` on boot.\
+The format for settings is described below.
+
+### Atmosphère Settings Format
+
+Settings are parsed from the `atmosphere/system_settings.ini` file during the boot process. This file is a normal ini file,\
+with some specific interpretations.
+
+The standard representation of a system setting's identifier takes the form `name!key`. This is represented within\
+`system_settings.ini` as a section `name`, with an entry `key`. For example:
+
+```
+[name]
+key = ...
+```
+
+System settings can have variable types (strings, integral values, byte arrays, etc). To accommodate this, `system_settings.ini`\
+must store values as a `type_identifier!value_store` pair. A number of different types are supported, with identifiers detailed below.\
+Please note that a malformed value string will cause a fatal error to occur on boot. A full example of a custom setting is given below\
+(setting `eupld!upload_enabled = 0`), for posterity:
+
+```
+[eupld]
+upload_enabled = u8!0x0
+```
+
+### Supported Types
+
+* Strings
+    * Type identifiers: `str`, `string`
+    * The value string is used directly as the setting, with null terminator appended.
+* Integral types
+    * Type identifiers: `u8`, `u16`, `u32`, `u64`
+    * The value string is parsed via a call to `strtoul(value, NULL, 0)`.
+    * Setting bitwidth is determined by the identifier (8 for 1 byte, 16 for 2 bytes, and so on).
+* Raw bytes
+    * Type identifiers: `hex`, `bytes`
+    * The value string is parsed as a hexadecimal string.
+        * The value string must be of even length, or a fatal error will be thrown on parse.
+
+### Atmosphère Custom Settings
+
+At the time of writing, Atmosphère implements two custom settings, found in the `atmosphere` section.\
+
+While not used for set_mitm, `power_menu_reboot_function` is loaded and controls the reboot behaviour of the console. By default, this value\
+is "payload", where the console will automatically reboot into the RCM payload stored in `sdmc:/atmosphere/reboot_payload.bin`.\
+(This payload is also used for fatal, upon a serious crash.) Setting the value to "rcm" reboots directly into RCM, and setting the value\
+to "normal" skips these behaviours.
+
+```
+[atmosphere]
+power_menu_reboot_function = str!payload
+```
+
+`dmnt_cheats_enabled_by_default` controls the behaviour of dmnt's cheat functionality. By default, this value is "0x1", enabling any cheats\
+defined by the user. Check [cheats](../cheats.md) for more information about Atmosphère's cheat functionality.
+
+```
+[atmosphere]
+dmnt_cheats_enabled_by_default = u8!0x1
+```
+
+`dmnt_always_save_cheat_toggles` controls the behaviour of dmnt's cheat toggle functionality. By default, this value is "0x0", causing toggles to\
+only be saved on game quit if a toggle file existed on game boot. Check [cheats](../cheats.md) for more information about Atmosphère's cheat functionality.

+If `count` is less than the size of the buffer divided by `sizeof(SmServiceRecord)` (the buffer was not completely filled), the end of the service registration list has been reached. Otherwise, client code
+should increment `offset` by `count` and call again. Client code should retrieve a record size using `AtmosphereGetServiceRecordSize`, and either make sure that the size of a record matches what it expects,
+or should make sure to use the correct size as the stride while iterating over the array of returned records. Example pseudocode is shown below.
+
+```

+record_size = AtmosphereGetServiceRecordSize();

+
 ### Minimum Session Limit
 
 When a service is registered, the sysmodule registering it must specify a limit on the number of sessions that are allowed to be active for that service at a time. This is used to ensure that services like `fs-pr`, `fs-ldr`, and `ldr:pm` can only be connected to once, adding an additional layer of safety over the regular service verification to ensure that those services are only connected to by the highly priveleged process they are intended to be used by.

+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+# emuMMC
+*A SDMMC driver replacement for Nintendo's Filesystem Services, by **m4xw***
+
+### Supported Horizon Versions
+**1.0.0 - 9.1.0**
+
+## Features
+* Arbitrary SDMMC backend selection
+  **This allows loading eMMC from SD or even SD from eMMC**
+* On the fly hooking / patching, fully self-infesting
+  **Only one payload required for all versions!**
+* File-based SDMMC backend support (from SD)
+  **This allows loading eMMC images from hekate-backups (split or not)**
+* SDMMC device based sector offset (*currently eMMC only*)
+  **Raw partition support for eMMC from SD with less performance overhead**
+* Full support for `/Nintendo` folder redirection to a arbitrary path
+  **No 8 char length restriction!**
+* exosphere based context configuration
+  **This includes full support for multiple emuMMC images**
+
+## Compiling
+### hekate
+Run `./build.sh` and copy the produced kipm (Kernel Initial Process Modification) file to `/bootloader/sys/`
+
+### Atmosphere
+Run `make`, the resulting kip can be used for code injection via fusee (place at `/atmosphere/emummc.kip`)
+
+## License
+**emuMMC is released as GPLv2**
+
+## Credits
+* **CTCaer** - The CTCaer hekate fork, file-based emuMMC support, SDMMC driver fixes among other things
