This article is about the official SDK by Nintendo. For the library used by homebrew, see libogc.

The SDK (internally known as RVL_SDK) is a set of libraries linked with every official Broadway title, containing general functions, and implementing an OS. It is responsible for sending calls to IOS, and is responsible for other features such as the HOME Menu and Bluetooth/Wiimote code. Because of the Wii's architecture, it is impossible for Nintendo to update the SDK in every title, although it may be possible with homebrew.

SDK versions generally correspond to major IOS versions, however, this is not an exact correspondence; one notable example is the SDK version used in Red Steel, which has a HOME Menu with different sounds.

Libraries

Many libraries can be identified by a string saying << RVL_SDK - NAME; this string also contains build info. However, libraries without that string can be identified by their functions, as all function names start with the library name.

Name Function
OS Full name is Revolution OS; responsible for things like context switching
RFL Full name is "Revolution FaceLib". For handling Miis.
