Basically, a few days ago I purchased an R4 Revolution. It was in a batch of other people's r4 fakes, and all of their fakes have been working fine for months. I got mine 4 days ago, and already the thing freezes up like crazy. I'll be lucky to play Retro Game Challenge for any longer than 10 mins before the game freezes up, and then I have to blow the hell out of the ds port in order to get the thing to read the card again. I'm really confused, because as far as I know, all roms worked great on my DS without any freezing, and the freezing now seems more random than anything. Is there anything I can do at all, I feel like I've been sold a dud, but everyone else's cards work fine. Also, I'm a complete idiot, I know NOTHING about tech. I just wanted an easy card that I wouldn't have to tinker around with constantly in order to get it to work.
