IOS21 is most commonly used by third-party games. It also contains a copy of the NAND Boot Program in content 1 in some versions, identical to the one in IOS15; this was most likely to apply an urgent patch to the Internet Channel.

It probably had the connection fixes advertised for 2.2. Many games such as Wii Sports were also rereleased under this IOS with a newer strap screen, probably in response to TVs getting smashed.

This IOS was used by older versions of DataChk, a factory title.
