I don't really know what cause this but hopefully you guys have some insight for me. My Wii just randomly decided to not work with some discs. They had been working find until a day or two ago. Two of the backups get disc read errors before the game can load. Animal crossing and at least one or two others will work and then crash about 30 minutes later. I am not sure why this happens. It happened on one Wii that has a d2pro and the other one has d2ckey. Anyone know if it would be a laser or modchip issue?
