Hi i have the GBA expansion pack which you get from the M3 Real Perfect bundle(rumble pack, GBA pack). On some occasions, my ds fails to detect the expansion pack and my GBA games sometimes freezes because it couldn't detect the GBA pack. How to I solve this? I solved the Loose Card Syndrome(Slot 1) by squeezing a piece of paper along with the cartridge, should i do this to the expansion pack as well?
