I got wiikey installed on my NTSC-U wii, and i've been running backup games, NTSC-U and NTSC-J just fine, but recently i can't seem to run red steel(NTSC-U) properly. It loads fine, I can enter the game right up to the part where you hav to create a save file, I can't get past that screen as a disk reading error shows up. Anyone has any solutions/ suggestions? thanks a lot.

I'm burning it onto DVD-Rs under 4x, im using nero to burn it. Bleach (NTSC-J), warioware (NTSC-U) works for me so far. all the originals works.
