i dunno if these are considered roms or not. i have some questions about flash carts for gba. from what i understand, it's a blank GBA cart that can store roms for later use on a real GBA. also, what's a good size for a cart? i see them in 128,256, 512, and 1024 mb carts. and is there any drivers or software required for transfering roms? all i have to use for the moment is a crummy mac. and software probably won't be written for mac if it's required.
