Stub variant2008

IOS3 is a stub IOS present in RVL-CPU-20 Wiis, whose functional version used by the Data Check and Log Check Helper, as well as the dummy titles installed by the Wii Backup Disc to install the development certificates. No console has been found with a functional version, and the functional version is more than 16 versions behind the state at the factory, so partial bits cannot be recovered either.

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.
