I have a WiiKey Fusion which can also load gamecube back ups. Yesterday we have been playing mario party 4 ntsc (I have a pal wii) without any problem. Today I tried loading mario party 7 which was on the same SD card, and all I got was a black screen. Then I loaded MP4 again and there was a black bar on the bottom of the screen, which wasn't there yesterday. I tried playing with settings, loading the sd card again etc but nothing worked. What could it be?
