Unfortunately for homebrew users, this deletes the majority of homebrew content, including the Homebrew Channel.

At midday, Nintendo rolled out a new version of the Wii’s System Menu, version 4.2. The update, which you now need to access the Shop Channel, hasn’t been officially announced yet, but appears to have some dire consequences for homebrew users. According to reports, the Homebrew Channel, BootMii (something popular for making backups of the Wii’s system data in case of a problem), and all custom IOS versions get overridden.

We haven’t been able to confirm the update’s effects ourselves, but we’ll let you know as soon as everything becomes clear. What can be said, though, is if you have any homebrew installed on your Wii, definitely don’t update for now!
