3DS:Open agb firm

open_agb_firm is a bare-metal application for running Game Boy Advance games using the Nintendo 3DS's native GBA hardware capabilities.

Features
open_agb_firm uses the 3DS's native capabilities to run GBA software, just like the original AGB_FIRM. The main difference is that it allows running ROMs from files on the SD card, instead of requiring them to be installed as digital games. Save files are also put on the SD card, making access to them far easier than AGB_FIRM.

Like AGB_FIRM, additional hardware features like accelerometer and camera are not supported. Games that depend on these features like and  will not work. The exception is the real-time clock which is implemented, so games that use this such as the third-generation Pokémon games can use it as normal.

Universal-Updater
open_agb_firm is available on Universal-DB and can be installed and updated with Universal-Updater.
