Version History
Preceded bySystem Menu Unknown Prelaunch
Succeeded by2.0

1.0 was the "update" containing the set of titles included with the Wiis on Launch Day. It was also likely what was installed by the Wii Startup Disc. Only a handful of channels were available (Disc Channel, Mii Channel, Photo Channel), and some not even activated yet (WiiShop Channel, Weather Channel, and News Channel).

System Menu 1.0 has no version listed; this version is assumed to be 1.0 due to the next update being 2.0, but some people simply refer to this as the "Default" update.

Differences from modern versions

November 19, 2006

  • The Disc Channel has a different icon that cycles between showing the "Wii" logo for a few seconds and showing a grey disc.
  • "Launch-Day" menu shipped with early Wiis. (Does not report a version number.)
  • No weather, news or shop channel available, Updates was only able through the update options in the internet settings.
  • Launching channels was a lot faster on 1.0U. There is no delay, If you press start on a channel, it immediatly goes to black, with the banner music still playing. This was fixed in the 1.0E and 1.0J


If you have a System Menu below 3.2 and wish to upgrade, use AnyRegion Changer to update.

WARNING: Be advised that if your system is shipped with 4.0 preinstalled, you can not downgrade and will brick your console.

If you have a System Menu above 3.2 and wish to downgrade, AnyRegion Changer can do this too, and it appears to do a more thorough job than some other tools. See WiiBrew:FAQ#Downgrading?.
