Im trying to put yu-gi-oh gx tag force 2 on my nephews psp, but it wont show up in the game part. He has 3.71 m33-2 the same as me and the game shows up fine on my memory stick. He also has the simsons game on his memory stick and that shows up fine aswell. I know that his memory card is fake, it says magicgate unknown, but my memory card is also fake and it works perfectly on mine. Any help would be great. Thanks.
