I am running 4.2U and am using the latest (as far as I know) CFG USB Loader. Anytime I try to load Madworld from my HDD, instead of the normal boot screens, (safety and wrist strap, etc.) the top-right quadrant of the screen turns grey. I can turn the wii off with the wiimote, (as opposed to if my wii crashes and i have to hold power in the console to power off.) Could this just be a bad ISO or is it a settings issue? Any help is greatly appreciated!
