Changes

The Wii Backup Disc was the only known official application to use [[IOS16]]. Because IOS16 is signed by Nintendo, and the update partition of the disc only has IOS16 and [[boot2v2]], homebrew install discs were released that used IOS16 and had a copy of the Wii Backup Disc's update partition.

When [[RVL-CPU-20]] consoles were released, IOS16 became one of the only IOSes that could be downgraded without issues, which resulted in general homebrew also installing IOS16 to get access to the [[signing bug]] and patch other IOSes.

Nintendo responded in the [[4.0]] update by releasing a stubbed [[IOS16]] (v512). It is unknown how the Wii Backup Disc worked after this point, although it may have instead been changes to use a newer IOS such as [[IOS36]], since IOS16 did not have anything critical to the Wii Backup Disc's function.
