IOS4 was a very primitive IOS that was used by both the Startup Disc Menu and the System Menu used in the factory process. This IOS and the System Menu come preburnt at the factory, before any other discs are inserted.
Like IOS10 and older versions of IOS9, this IOS does not have a build tag.
U.S. update partitions are set to use this IOS in their TMD. Other regions are not yet known.
IOS3 and IOS4 are also the only two IOSes stubbed on the Wii mini, since most IOSes will hang on the Wii mini due to the WiFi module not responding.
The SDK version that uses IOS4 probably only supports 4:3 video; this is evident in the Wii Startup Disc's SDK, which most likely uses IOS4.
Titles using this IOS
- Factory System Menu
- Unknown 123J disc
- Startup Disc Menu
- Wii Startup Disc
- Update partitions
