Nintendo Wii System Menus
Pre 1.0 (Version 0) - Remnants of this System Menu were found on the leaked 'Wii Startup Disc' NAND. It is unknown which IOS runs this menu. It could be IOS4v1 (remnants of this IOS were also found on the leaked NAND). There are no known images of this Menu. Essentially, nothing is known about this menu except that it did exist and it was only available for use during Factory setup.
Pre 1.0 (Version 1) - Also known as the Wii Startup Disc Menu. Some pre-release Wiis were shipped with this menu (and the Wii Startup Disc), for certain stores to setup the Wii to install the 1.0 System Menu. The Menu contains a image of the Wii and Startup Disc, with messages (in English, French, Spanish) instructing you to insert the Disc to setup the Wii. Menu runs on IOS4v3.
1.0J 1.0U 1.0E (Versions ??, 33, ??) - Came on most pre-release Wiis and on a small amount of 'Launch Day' Wiis. On the Wii Settings, there is no version number on the top right. Came with minimal channels (such as Mii channel). WiiConnect24 option was disabled. There were no options to change Country on the 1.0U Version. 1.0U and 1.0E runs on IOS9v516. While 1.0J runs on a version of IOS10 which we do not currently have for retail Wii's at this moment.
2.0J 2.0U 2.0E (Version 130, 97, 128) - Most Launch Day (American) Wiis came with this Menu. 2.0 allowed the ability to choose Country of residence, parental control settings added, ability to rearrange channels, and added SD card support for savegames. More basic channels included. For the 1.0 Wiis, an update was available to upgrade to 2.0U (needed to be done in order to play games, so update was basically forced). 2.0U Menu Release date (also release date of Wii) is Nov 19, 2006. 2.0J was released on Dec 2, 2006. 2.0E was released for Australian Wiis released on Dec 7, 2006, and for European Wiis on Dec 8, 2006. 2.0 Menus run on IOS11v10.
