Im using an M3 SD, and on some games the sound breaks up/cracks/stops, particularly Meteos and Ouendan. It usually only does it in the menus when I select something and it loads into another screen. So, I'm guessing this is because my SD card isn't fast enough for some of the games? Or is it just an M3 thing? I'm using a Kingston Elite Pro 1gb SD card, it's 50x. This isn't really a big deal but I was wondering if anyone has had a similar problem and knows what the cause of it is.
