If you like the idea of using a Wii for homebrew apps, then you better not install the new Wii System Update, at 3.3. Nintendo is trying to hide this update under the guise of a new Mii Channel bug fix, one that would allow a player to move a Mii from the Mii Plaza (the default area for the Mii Channel) to the Mii Parade (the one that allows you to share Miis). This is problematic!
The update also includes functionality that will delete any modified save files that are “unauthorized” because they could “impair gameplay or the Wii console” itself.
If you are a homebrew fan or someone who wants Linux on their Wii, DO NOT INSTALL VERSION 3.3 of the Wii Menu Software.
