I have an AGB that is acting a little funny - it won't always read games the first try. The carts fit nice and tight, but I have to fiddle with them to get everything to work. When they don't read, I get a blank screen, or I get a boot screen with a garbled Nintendo logo. It's not the carts - I can put the same carts in my AGS and they work fine every time. What can I do?
