==Software==
The Wii runs [[IOP-OS]], a custom microkernel OS developed by [[BroadOn]]. This OS runs on the [[IOP]] (an ARM9 core inside the Hollywood package) while game software runs on the Broadway. The Broadway does not run an OS, but an [[RVL_SDK]] "Revolution OS" library is used to provide some basic services to applications.
The Wii was also shipped with some user-facing Broadway applications providing additional functionality to the system, including the Wii System Menu and the Wii Channels.
Since each piece of software (including individual Channels, IOS and the Wii System Menu) is packaged as a discrete [[WAD]] file, an OS update includes a WAD for each updated component.
The official OS update versioning system correlates to System Menu updates; some updates of individual components were distributed which do not update the version number.
