i am having trouble loading mario kart wii (ntsc), the original copy, burnt or iso will try to load and right after the wiimote strap disclaimer screen it will fade to black and lock up there. however when i try to use an iso of a pal copy and force ntsc, it will load perfectly fine. would anyone have a clue of what the issue might be? i am on system menu 4.0 and using cios rev10.
