'''IOS12''' is an [[IOS]] that was previously thought to be the oldest,{{ref|[https://hackmii.com/2009/06/ios-history-build-process/ "IOS: history, build process" on HackMii]}} but that was due to an outdated build date of June 4, 2006, probably from [[IOSP]].

IOS12v6 is most likely a copy of IOS11v6, since both IOS11 and IOS12 have NCD modules that use [[:/shared2/sys/net/02/config.dat]], while [[IOS5]] is known to have an NCD module that uses [[:/shared2/sys/net/config.dat]] due to the code responsible for deciding on the config file using the latter on every IOS before IOS11.

The [[SDK]] version built for IOS12 only supports 4:3 video.
