IOS55 is an IOS that newer games/titles appear to require or use. Some examples are:
- Call of Duty: Modern Warefare - Reflex Edition
- The Conduit
- Donkey Kong Jungle Beat (New Play Control)
- Excite Bots
- Need for Speed: Undercover
- Sonic and the Black Knight
- Wii Sports Resort
- Internet Channel
This IOS is presumably required by NfS: Undercover to make a Logitech USB steering wheel work. However, this does not explain why the other games require it although, in the case of The Conduit, it is possible that there is a connection between its usage and support for the Wii Speak peripheral (it has been reported that both IOS38 and IOS55 are required by the official Nintendo Wii Speak channel).
Typically, if a game that requires this IOS is started without it (via brickblocker or a Starfall update skip, for example), then the screen will turn blue and a white-text error message "Error #002" will appear. The Conduit behaves somewhat differently as it will simply display a black screen before freezing.
