Startup Disc Menu
The menu can be in one of the following states at any given point:
- Waiting for a disc to be inserted ("please insert the Wii Startup Disc")
- Checking the inserted disc ("checking disc")
- Installing the contents of a disc's update partition (also "checking disc")
- Non-RAAE or autoboot disc inserted ("incorrect disc")
- Other disc-related error, including a disc drive fatal error ("error has occurred")
The following states have graphics data present in the menu, but it is unclear if they are used:
- Installing the contents of the Wii Startup Disc ("installing, do not touch the console")
- Prompting the user to remove the disc ("please remove the Wii Startup Disc")
- Stating that installation has already completed ("Wii Startup installation has already completed")
Since the Startup Disc should normally overwrite the System Menu, the last image should never appear in the Startup Disc Menu; that indicates that these assets were copied from the source tree for the executable on the Startup Disc itself, and are probably unused in the Startup Disc Menu. Using software rendering on older versions of Dolphin for Android can cause the "installation already complete" message to appear.
The menu uses IOS4, specifically IOS4v3 which is included on each Startup Disc Wii.
The menu performs a unique fade-to-black animation upon launching titles.
The menu has three possible colors for the background of each scene's text; blue, orange, and red. Red is only used by the error screen, and orange is only used by the "already completed" screen and the "incorrect" screen.
The menu contains 3 sound files, 1 of which is (seemingly) unique to this menu. One sound file is used for the opening of the menu and the error screens, one is used during installation, and one is used when installation is completed. The installation sound is the same as the normal system menu's "save file copy" sound, and the finishing sound is the same as the normal menu's "save file copy finished" sound; it is unknown if the error sound is used elsewhere.
Revolution Error Screen
The menu has an early version of the DVDFatal error screen with text referencing the "Nintendo Revolution Instruction Booklet". The menu disables the function that makes this message appear to allow for the red error screen to appear instead. Manually re-enabling it by editing an instruction causes the menu to cut to black instead, but no error text appears.
