I have the acekard 2i cart and recently it has been freezing on occasion while playing DS games. I've heard using a can of compressed air to clean the slot one area is a good way to solve this sort of issue. Can someone please give me clear directions on how to do this. Don't wanna make the problem worse by spraying improperly. Also just incase you're wondering, I did indeed use the Panasonic SD formatter right after buying the DS Lite and acekard.
