3DS-Linux
---------

It's Linux(R) on the 3DS(TM), but it's even more modern, and works well!
What works and works well:
- Booting
  - Booting properly to a TTY on original 3DS consoles (2DS and 3DS XL too)
  - Booting from the Luma3DS custom firmware
- Hardware
  - RAM : all 128MB of FCRAM are usable
  - Using VRAM to store the framebuffers in RGB565, allowing all RAM to be usable by linux
  - SD Cards
  - Virtual keyboard on the bottom touch screen
  - Graphics output on the top display in 400x240, using either the Linux VT, or anything that writes to /dev/fb0 (e.g. Xorg)
  - Battery status reporting
  - Circlepad input as mouse movement
  - Gamepad buttons exposed as GPIO
  - Notification LED (unused but support is present)
  - Internal STMicroelectronics LIS331DLH accelerometer
  - New! Atheros AR6014 WiFi adapter
- App support
  - Most applications that you would want to use - anything in Void Linux officially
  - X11 Windowing system - lightweight Window Managers / Desktop Environements will work

What works if you ignore the obvious problems:
- Powering off the console from linux (kernel panics right before powering off)

What doesn't work at all:
- Sound
- Booting from Horizon OS (no way to get complete hardware control once HOS starts)

What isn't tested:
- Booting on New 3DS consoles (New 3DS XL and New 2DS XL too) - I dont have any, if you would like to test and give feedback, contact me
