open_agb_firm
open_agb_firm is a bare metal app for running GBA homebrew/games using the 3DS builtin GBA hardware.
Disclaimer
We are not responsible for any damage that may occur to your system as a direct or indirect result of you using open_agb_firm.
How to build
To compile open_agb_firm you need
- devkitARM
- Corelink DMA-330 assembler
- CTR firm builder installed in your system. Additionally you need 7-Zip or on Linux p7z installed to make release builds. Also make sure the CTR firm builder and dma330as binaries are in your $PATH environment variable and accessible to the Makefile. Build open_agb_firm as debug build via
makeor as release build viamake release.
Known issues
This section is reserved for a listing of known issues. At present only this remains:
- Sleep mode is not fully implemented.
- Save type detection may still fail for certain games using EEPROM.
- No settings (including brightness control), no cheats and other enhancements. If you happen to stumble over another bug, please open an issue in the official open_agb_firm repo on GitHub or contact me via other platforms.
Hardware limitations
This is a list of limitations we can't solve in software or are very hard to work around. This doesn't mean it will never happen (unless stated otherwise).
- 64 MiB (512 mbit) games. Not possible to support.
- Games with extra hardware built into the cartridge (except Real-Time Clock). Patches are required.
- GBA Serial port (aka. Link Cable).
- 64 KiB (512 kbit) SRAM (homebrew games/emulators). Not possible to support.
- Can't switch back to 3DS mode from GBA mode requiring a reboot for booting a different game.
- Savestates. Very difficult to implement because no direct hardware access.
Troubleshooting
Known problems and the solution. Problem: The game crashes/shows white or blackscreens or shows a savegame corrupt message. Solution: Try to delete the savegame file. If this doesn't help report the issue. Note: EEPROM saves made by some emulators are incompatible because they have every 8 bytes block endian swapped.
