I have some backups of my gamecube games that arent working. They load up showing the game but then i get a black screen saying there was an error and to check the gamecube manual and reset the system. Has anyone else encountered these? I have a cyclowiz installed. Now mind you many other gc cames work fine just about 5 so far that I have come across. Could this be the chip and possibly fixed with an update or bad dumps?
