Hi, I am using trying to load Mario Power Tennis (New Control Play) US version using WiiFlow but only a black screen shows up when I press play. I have done some searching but no one else seems to have this problem. I have also tried using USB Loader GX but I get the same result (just a black screen). I have system menu 4.0 U. Does anyone know how to fix this problem? ps. everyother game I have works. It's just this game that doesn't.
