## What it is
open_agb_firm is a bare metal application that runs Game Boy Advance games and homebrew natively on the Nintendo 3DS using its built-in GBA hardware. It serves as an improved alternative to GBA VC injects, launching ROMs directly from the SD card with save support, button remapping, and display correction options.

## Use cases
- play GBA games on a 3DS without VC injects
- run GBA homebrew on real 3DS hardware
- save GBA game progress directly to the SD card
- fix washed out colors on GBA games with gamma correction
- remap buttons for GBA games on 3DS
- launch .gba ROMs from a file browser on 3DS

## When to choose
- you have a hacked 3DS and want native GBA compatibility
- you want better video output than AGB_FIRM VC injects
- you need direct SD card save support for GBA games

## When to avoid
- you want to emulate GBA on a PC or other platforms
- your 3DS is not running custom firmware like Luma3DS or fastboot3DS
- you need emulation features like save states or fast forward

## Facets
- artifact type: application
