So I got an R4, and it has been great, but lately there have been some GBA games I've wanted to play. Is there a slot 2 card that is available that is cheap and handles GBA well (good compatibility, speed)? As I already have an R4, I wouldn't need the slot 2 card to load DS stuff, but the other Slot 2 addons seem nice 2 (rumble pack, ram upgrade). Are there any that run on minisd cards? I was looking at reviews for some and they seemed to only hold one gba game at a time? Anyway, any help on this would be greatly appreciated.
