Thanks DiscMurderer, I'll check this. However, my physicial memory card is recognized. The wii knows it's there. I just can't load a previously saved game on this particular game (def jam fight for ny). I was thinking, could there be a possibility of a difference between a USA or NTSC game vs EUR or PAL game?
Because if there is, I might be using an USA game on my PAL system. I don't know if this applies to NGC games.
