The [[vWii]] use a slightly different set of [[IOS]] versions. They can be downloaded from NUS, but use a title ID starting with 00000007 instead of 00000001 and encrypted with the vWii common key; this title ID only applies when downloading, not when installed.

'''vIOS''' is the [[vWii]] equivalent of [[IOS]]. vIOSes can be downloaded from NUS, but use a title ID starting with 00000007 instead of 00000001 and encrypted with the vWii common key. This title ID is only used for the download URL; everything else, including the [[TMD]], uses the 00000001 ID. See [https://wiiubrew.org/wiki/Title_database#00000007_and_000700xx:_Virtual_Wii_titles title database on WiiUBrew].
