I purchased Wario Ware, Mega Microgame$ for the GBA from Gamestop and I think it might be a bootleg. Don't have much evidence, but although the cartridge looks the same as my other GBA games, and the artwork looks really good, I have to use a bit of force to put it in, and take it out of, the GBA slot on my DS (unlike all my other GBA games which slide in and out easily). Also, when I tilt the game to the side, so I can see the inner cartridge board, I don't see the NINTENDO label, unlike a couple of other GBA games I looked at. Anyone have any ideas?
