R4i keeps freezing whenever I start a game.

Some games continue to stop whenever I start. I've tested this on a large variety of games... Old and new like Kingdom Hearts (patched) and Tranformers Animated [lol], so I don't think it has anything to do with firmware...Any help (and a link to the newest R4i Ultra firmware) appreciated.I have a used the "Tell the difference between fake and real R4i" and mine is real.
