 # Changelog
+## 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.

+# 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

 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 (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. 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.
+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 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.

-custom settings will be documented here as they are added.
+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.

+
+`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.

+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+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:

+# emuMMC
+*A SDMMC driver replacement for Nintendo's Filesystem Services, by **m4xw***  
+
+### Supported Horizon Versions
+**1.0.0 - 8.1.0**
+
+## 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
+* **SciresM, hexkyz** - The Atmosphere project, FS offsets, additional research related to newer FS versions
+* **naehrwert** - The hekate project, its SDMMC driver and being very helpful in the early research phase
+* **jakibaki** - KIP Inject PoC, used in the early dev phase
+* **switchbrew/devkitPro** - devkitA64 and libnx sources
