Hi, I just got my Supercard DS1 today and I tried loading up Castlevania DOS to watch intro. It lags after the bats fly away. I tried changing to a higher speed, but it still lagged. When I did the auto set sd speed, it only gave me 16. I have the A-data 4GB SDHC Class 6 card. Anyone know why I'm still lagging with this fast card? EDIT: I have a fat ds if that matters and I have used about 2GB of the memory so far.
