Hi, I just bought a acekard 2 v2.1 and i bought a micro sd card, put the official firmware on it, put my roms on it and now on almost every game it freezes after menu screen. On the couple roms that do work they freeze when you try to save. I've tried both AKAIO and official firmware. At first I thought maybe it was the micro sd ( I was using a Taiwanese kingston ) so I bought a sandisk 4gb micro sd. After a little while I was fed up so i called the store I bought it from and they thought it was defective so I mailed it back and this one does the same! please help !
