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).
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.
