Well i just downloaded call of duty 4 reflex onto my usb and i opened it with my usb loader and it just makes the screen go black, if i force pal50 there are lines and if i force pal 60 its just black if i force ntsc then it is also black. my console is a ntsc and the iso is a pal but i have done this with other games and they have worked so i dont know what the problem is. the wii is on 3.2u aswell.
