System Menu

The System Menu is software shipped pre-installed into every Wii which allows the launching of games from an officially Nintendo certified game disk, launching of Nintendo Certified channels and Virtual Console and WiiWare titles.

On an un-modded system, it is the first thing a Wii user will see when s/he turns on his/her Wii having pressed 'A' at the Health and Safety screen. An X denotes that no version is available for the applicable region.

Homebrew Alternatives

With the development of BootMii, the idea of booting straight to Homebrew may soon become a reality. In light of this, there are a couple of projects out there to create a homebrew-friendly System Menu alternative, such as WiiMU.
