I am not sure what to do about this but I just got a brand new acekard and a class 2 sdhc 8gb sandisk card. Moonshell 2 gets a white screen sometimes and others an arm9 error. I format my card with the panasonic card formatter. Games work but they dont save and some hombrews don't work. pretty much all things go wrong. I am not using AKAIO im using official firmware. Could it be because the card is a class 2? What do the classes mean? Will buying a class 4 solve all my problems and can I fix the problems without buying a class 4? Big thanks to anyone who can help me get this working. Edit: I used to have to prepare files then drag all of them card when I had my r4 and thats what I would have to stick with untill I reformatted. I thought since this is a better flash cart maybe that wouldn't be the case but tell me if im wrong.
