I bought a Penguins of Madagascar Game for my DS, and everytime I put it in, it wont work. I have a Japanese DSi, and the game wont show up on the menu. I have used a Action Replay DSi, to see if I could bypass that, and it can detect the game, but it says "Unknown game", and when I try to load it, it wont run the game either. Do I have a faulty game cartridge? Or is it because of my Japanese DSi?
