95% of the time my DS will freeze on boot at the health and safety screen when I have my new Acekard RPG in it. It seems to me that the metal casing for the microSD is sticking out a little bit and might be throwing the contacts off. I don't think there's anything wrong with the card itself since I can transfer files and the UI works fine (when I can get to it), but games freeze when I try to play them. Metal Slug 7, for example, freezes after taking several steps forward on level 1. Has anyone else had a similar problem and fixed it or should I start looking for a new card?
