|Features of the emulator
You can look at these features in the ReGBA Manual on your device. Press Select with ReGBA selected in gmenu2x, then choose "Show manual of ReGBA".
*Loading ROMs, both uncompressed and compressed in zip format.
*Synchronised video. Optionally scaled to full screen, and optionally preserving the aspect ratio of the image, using two scalers.
*In-game saving and saved states (see below for more information about saved states).
*Rebinding for all GBA buttons. The emulator has a menu you can enter with a customisable hotkey (default is X). You can use the menu to reset the game, exit to gmenu2x and set some settings. They are saved to a file, so you can use your favourite scaling, FPS counter, boot screen, remapping and hotkey settings all the time.
*Per-game settings, so that you can use the same settings for most games but override them as needed. Press Select at the ReGBA Main
*Menu for the per-game settings.
*Bundled game_config.txt for greater compatibility, as well as overrides in /local/home/.gpsp/game_config.txt.
*Bundled open-source GBA BIOS replacement by Normmatt, as well as the ability to drop the Nintendo GBA BIOS in /local/home/.gpsp/gba_bios.bin.
*A border when the GBA image is shown on the screen without scaling. You can override this border by putting one at /local/home/.gpsp/border.png.
*Automatic and manual frameskip.
