I burned a patched version of nsmb and ran it with neogamma r7 and it was working great! no problems with the game. I stopped playing for about 3 days and when I went to load it back up, it started giving me the "Disc Could Not Be Read" error after the controller screen. I've looked on all the posts in this forum and others about people having the same problem, but I don't understand why my copy was working smoothly until now? Any suggestions? Could it be just a bad disc?

Thx
