The System Menu, more commonly known as the Wii Menu, is software shipped pre-installed into every Wii as title 1-2, which allows the launching of games from an officially Nintendo certified game disc, as well as the launching of other titles marked as channels. While the System Menu detects channels and discs and displays banners, IOS is responsible for the actual launching of the channel through ES_LaunchTitle.
Contrary to what may seem true, the System Menu is not an operating system; it only runs when a game is not in use. All graphical elements when a game is open, such as the HOME Menu, are part of the game disc. However, the System Menu does have higher privileges than most titles, allowing it to do things such as updating and deleting titles.
SD Card Menu
With the 4.0 update, SD launching was added. Unfortunately, due to the limitations of how titles are loaded by IOS, titles cannot be directly launched from the SD card. All titles have access to the SD slot, and only one processor can access the slot at a time, complicating this. Nintendo solved this by simply copying all channels to the NAND at runtime, which is why unsigned channels cannot be run this way.
The System Menu plays a major role in the startup, shutdown, and transitions between system states; upon starting up, the System Menu's main() reads the following files:
Based on the things read by main() (as well as certain flags set in memory?), the menu can take the following actions:
- Hang (unrecoverable brick!)
- Boot a disc title directly from cache.dat
- Shutdown system from GC mode
- Eject a disc, then shut down (if Eject was pressed)
- "Shutdown to idle" (Enable WC24, halt PPC)
- "Launch NAND app from WC24"
- Enter "recovery mode" (aka IRD mode)
- Display the Health / "Warning" screen, and proceed on with normal boot
On an un-modded system, it is the first thing a Wii user will see when they turn on their Wii having pressed 'A' at the Health and Safety screen.
The disc-handling actions of the System Menu are governed by a complex state machine known as BS2.
The version number can be found by clicking on the "Wii" button in the System Menu, and then choosing "Wii Settings". The version number is displayed in the top right corner of the screen. This works for all versions except for 1.0, where the version number is not visible. An X denotes that no version is available for the applicable region.
The version identifier consists of two parts: revision (version) number and the geographic region.
For example, 4.3EUR v514, denoted as "0x202, 0x20(32)" (in data) is the actual version and 2 the region EUR.
|Version||JAP||USA||PAL||KOR||Release date||IOS||Changelog||CDN Availability||CDN Post Date|
|Prelaunch||X||0 (0.0)||X||X||Never publicly released||Unknown||Prelaunch Development. Basically, nothing is known about Version 0 of the Prelaunch System Menu. Remnants of this menu were found in the 'Wii Startup Disc' NAND dumped by bushing. The Version 1 of Prelaunch Menu has a screen displaying "Please Insert the Wii Startup Disc..." but it's not known if Version 0 even has this message let alone the background images/colors of Version 1. Remnants of a IOS4v1 were also found in the NAND, so it is possible that's the IOS that runs Version 0.||Unavailable||Unavailable|
|Prelaunch||X||1 (0.1)||X||X||Never publicly released||IOS4 v3||Prelaunch Development (Does not report a version number.) System Menu has text displaying "Please Insert the Wii Startup Disc. This will set up your Wii Console." Spanish and French versions of message also listed. Contains an image of the Wii Startup Disc with an arrow pointing at an image of a Wii. (The following info may be for a different system menu) CaptainChris2018 used the prelaunch system menu in the dolphin emulator, he tried putting the Mario Kart Wii and Wii Sports iso's in the virtual drive, and they did not work, he tried a Super Smash Bros. Melee iso,(which is a Gamecube game) in the virtual drive, it did not work ever. I guess with my tests, maybe you need a special disk for it to work.||Unavailable||Unavailable|

Please feel free to add more changelog entries. Some information was taken from Nintendo.
With the release of BootMii, the idea of booting straight to Homebrew may soon become a reality (BootMii does have an option to autoboot to the homebrew channel, but there is no way to autoboot to any other homebrew without Priiloader). In light of this, there are a couple of projects out there to create a homebrew-friendly System Menu alternative, such as WiiMU.
