If i put an action replay rom on my R4, would it function for cheating on legit DS games?
No you can't use Action Replay rom on R4, yes you can use Adventure Replay, RPG Replay, Sports Replay, Puzzle Replay, and Fighting Replay roms on R4.
And Pet-Simulation Replay!No you can't use Action Replay rom on R4, yes you can use Adventure Replay, RPG Replay, Sports Replay, Puzzle Replay, and Fighting Replay roms on R4.
oh yes, i may have forgot about those, those are VERY helpful, oh, but you forgot Turn-Based Strategy Replay, Platformer Replay, Party Replay, and Virtual Life Replay
