Wii Backup Disc

The Wii Backup Disc is a service disc apparently used inside Official Nintendo Repair shops to transfer personal data like savegames and console settings between Wiis as part of a repair. It's not entirely clear what it does; something it does not do — even though it appears it might — is allow VC games to be transferred between consoles. Instead, it transfers the license so that the user can redownload the games from Wii Shop Channel for free.

There are two known versions of the disc (one pink, one blue), each showing kissing fish on the label.
