DiscUpdate Disc
From Rare Gaming Dump
This disc was discovered through an image (TODO: insert image) showing this disc, as well as the Movie-CH Install Disc and the Wii Backup Disc. This disc was also seen in the GameDealDaily image, but is no longer available on their site. In late 2018, this disc was obtained and dumped, revealing that it installs updates through the Wii Menu and contains a checker program listing titles which the disc should install and verifying that they are installed.
