If you are looking for the gba-bios_bin download for your iPhone/iPod Touch then you have come to the right place. I frequently get emails from many visitors to this site asking how to get gba4iphone to play GBA ROMs. gpSPhone does not include the gba_bios.bin file which is the file that is needed to get the player to work. I have looked around and found a working download link for this file. Before you download this file, please remember to click the disclaimer tab in the above right.
