On March 21st, Nintendo added a new version of the Wii firmware -- IOS37 -- to the Wii update servers. This version of the firmware has a fixed signature-checking function.

When a title (game, channel, etc) starts, it tells the system menu (using a field in the TMD) what version of the IOS it needs to run on -- to support this, the Wii stores all previous firmware versions. (For most Wiis, this will be IOS9, IOS11, IOS13, IOS15, IOS17, IOS20, IOS21, IOS30, IOS31, IOS33, IOS34, IOS35, IOS36, and now IOS37).

IOS37 fixed the signing bug, and this fix has been added to all other IOSes. This IOS is used by several WiiWare games, and older Guitar Hero/Rock Band games.

IOS37 was most likely forked from IOS35v1040, since many of IOS36's modules are on the Release/apricot-win/SDK_FW_36_4_18_branch branch, while the corresponding IOS37 modules are on the Release/apricot-win/SDK_FW_30_4_13_branch branch, similar to IOS35.

IOS37 replaced the FFS module with an FFSP module and the KBD module with a USB_HID module.

It is also one of four IOSes not fixed in 3.3rev03, and instead had its ES_Identify and /dev/flash fixed in 3.4. The other IOSes not fixed at this time were IOS30, IOS31, and IOS16 (not fixed until 4.0)
