open_agb_firm is a bare metal interface for natively running GBA games and homebrew using the 3DS's built-in GBA hardware.
What's New:
* ROMs bigger than 32 MiB are now allowed but data beyond 32 MiB is cut off and a warning is displayed. This will make certain ROM hacks load at the cost of likely crashing later on. You have been warned.
* Taking screenshots no longer freeze occasionally and they are created with date and time in the name.
*And many fixes.
