I'm looking for a way to play GBA roms on an actual GBA, and more importantly, read/write saves to my from/to my existing GBA games. This is mainly for backing up and modding pokemon saves, so the gen4 games would need to see the save as a valid gen3 pokemon game. I found this, but all the links redirect to the same site, and they don't have it listed anywhere. Does anyone know where I can find one, or something similar?
