I've had Mario Kart 8 for some time now and had no problem with disc reading ever with my system but all of the sudden I'm having issues out of the blue. I've tested every other physical copy of games even wii discs with no error with MK8 being the exception. This disc is far out of it's warranty and is devoid of any scratches or marks. So what made this happen with no warning? I have no clue but if anyone has any suggestions i'm open to them.
Just to brief i have deleted all data and updates from the storage menu, wiped the disc with microfiber, turned the WII U horizontally, unplugged for 2 days and retried and used the pro controller with and without. I'm out of ideas at this point.
