Additionally this can 'force' an upgrade by requiring the player to perform the update, without which the new game cannot be played. Several game discs, both first-party and third-party games, have included system software updates so that players who are not connected to the Internet can still update their system. When a new update becomes available, Nintendo sends a message to connected systems notifying them of the available update. Updates, which are downloaded via the system's Internet connection ( WiiConnect24), allow Nintendo to add additional features and software. Wii system software is a set of updatable firmware versions, and a software frontend on the Wii video game console.
