So I'm having problems with a couple games on my acekard 2i. There are a few that seem to run like theyre in slow motion and eventually stutter to a freeze. Specifically the tony hawk games, the zelda games, and the new rhythm heaven game. I've read a few places that maybe its my sd card. Im using a sandisk 4g micro sd and maybe thats too slow? I've read that there are class 6 sd cards that run faster and can solve game slowdowns but im not sure where to get one or how to tell the speed of a card. Anyone having a similar problem and can confirm or deny that the sd card might be the source?
