Im currently attempting to play a backup of Super Mario Sluggers but it keeps popping up with the error "The Game disc could not be read. Refer to the Wii Operations Manual for details." I'm burning the games at 3x speed on Fujifilm DVD+Rs with ImgBurn. Any advice at how to fix this. I've tried both Fujifilm DVD+Rs and Memorex DVD-Rs and the same problem. Should I try different speed like 2x or Max? Or is there a specific type of DVD that works?
