The patent for the Wii U shows a similar device which is simply named 'Input/Output Processor'. The currently active IOS, also simply referred to as just 'IOS,' runs on a separate ARM926EJ-S processor, unofficially nicknamed Starlet. The Wii's firmware has many active branches known as IOSes, thought by the Wii homebrew developers to stand for 'Input Output Systems' or 'Internal Operating Systems'. Not to be confused with Apple iOS or Cisco IOS. Brawl and Mario Kart Wii, contain specific extra updates, such as the ability to receive Wii Message Board posts from game-specific addresses therefore, these games always require that an update be installed before their first time running on a given console.

Some games, such as online games like Super Smash Bros. The system menu will not start such games if their updates have not been installed, so this has the consequence of forcing users to install updates in order to play these games. Most game discs, including first-party and third-party games, include system software updates so that systems that are not connected to the Internet can still receive updates. When a new update became available, Nintendo sent a message to the Wii Message Board of Internet-connected systems notifying them of the available update. Updates, which could be downloaded over the Internet or read from a game disc, allowed Nintendo to add additional features and software, as well as to patch security vulnerabilities used by users to load homebrew software. The Wii system software is a discontinued set of updatable firmware versions and a software frontend on the Wii home video game console.
