Fastfs testing

- Errors will now be more precise, there are now 2 separate errors for a function lookup failure and a failure inside a function
- Errors will now show which line number they failed at, instead of the character offset
- Minus values are not considered errors anymore, however, printing them does not work well
- Gotos now make a @RETURN variable to make making functions easier

 # TegraExplorer
 A payload-based file explorer for your switch!
 
+![TegraExplorer builder](https://github.com/suchmememanyskill/TegraExplorer/workflows/TegraExplorer%20builder/badge.svg)
+
 ## Usage
 1. Get your favorite payload injector
 2. Inject TegraExplorer as a payload
 
-Navigate around the menus using the vol+, vol- and power buttons
+Navigate around the menus using the joycons.
+A: Select
+B: Back
+Left Joystick up/down (Dpad or joystick): navigate menus up/down
+Right Joystick up/down: fast menu navigation up/down
+Capture (Minerva only): Take a screenshot
+L3/R3 (Press joysticks in): Recalibrate centerpoint
+
+If you do not have your joycons connected:
+Power -> A
+Vol+ -> Left Joystick up
+Vol- -> Left Joystick down
 
 ## Functions
 - Navigate the SD card
-- Navigate the System partition of your sysnand/sysmmc
+- Navigate the System partition of your sysmmc and emummc
 - Interact with files
-	- Deleting, copying or moving files
+	- Deleting, copying, renaming and moving files
 	- Launching payloads files
 	- Viewing the hex data of a file
+	- Launching special [TegraScript](https://github.com/suchmememanyskill/TegraScript) files
+	- Renaming files
 - Interacting with folders
-	- Deleting or copying folders
+	- Deleting, copying or renaming folders
+	- Creating folders
 - Dumping your current firmware to sd
 - Formatting the sd card
 
+*and more*
+
