I formatted my HDD to WFBS, and converted the IOS for NSMB to .wfbs file format. It is a PAL version of the game, and when I try to play it, I get purple, blue and green verticle lines on the screen. I tried it again forcing PAL50 and got a solid green screen. Tried it again forcing PAL60 and got the same purple, blue and green lines. Anyone have any suggestions?
