this is probbaly the most common question pepole ask me. so first if your games arnt playing check to see if the disks have any scratches dirt dust or finger prints.if they do take a cloth and carefully clean the disk from the edges in a circuler motion.another reason could be that your games where not made in the usa.or your wii has stuff inside the disk slot DO NOT try to take apart the slot and try to fix it.you should call your wii aporater or nintendo to get it fixed.hopes this helped.
