A Wii System Update is an upgrade to the Wii's internal firmware. They are distributed by Nintendo in one of several ways:

  • Being included on a Wii Optical Disc with a game that requires it
  • Included with a Message Board message about it
  • Updated manually from the "Wii System Update" choice in the Wii Options, or after testing a connection in the "Internet" setting.

Such Wii System Updates may include new WiiConnect24 functionality, upgrades to preinstalled Wii Channels, new channels, support for downloadable channels, Wii Menu or Message Board design changes, repairing crashes, and blocking illegal loading devices such as the FreeLoader by Datel.
