Hey all, I am an owner of an M3 simply, and my friend wants to buy it off me, so I said sure. I'm taking this oppurtunity to buy a better rom cart. I am mainly looking for the best compatibility, because it sure is a pain to get the newer ds games to work on my simply. It takes a lot of patching, which dosnt work out most of the time. Anyways, I would like high compatibility, and high functionality. Is there a card that does gba games yet? That would be a plus. Big storage is also a plus. Just tell me which card you think is the best!
