So I'm aware that you can't emulate GBA games on a slot-1 card, but I was wondering... is there any kind of Action Replay tool for slot-2 games? I mean, if you were to have the actual game in slot-2, load some kind of Action Replay-esque tool from a slot-1 card, and then play the slot-2 game with whatever codes applied. Is there anything like this out there?
