The Legend of Zelda: Skyward Sword Save Data Update Channel

The Legend of Zelda: Skyward Sword Save Data Update Channel, known on the Wii Menu's Title Screen as Save Data Update Channel For The Legend of Zelda Skyward Sword, Save Data Update by the Wii Message Board, and Zelda Data Restoration Channel in Japan, is a channel for the Nintendo Wii system, made available on the Wii Shop Channel for free in December 2011. This channel is the first available on the Wii Shop Channel to feature a screen reading "the download of this software is only advised to those who own a copy of (specified game)".

This channel came into fruition after Nintendo became aware of the infamous Song of the Hero glitch in The Legend of Zelda: Skyward Sword, a bug that can potentially prevent completion of the game. This channel was first announced when Nintendo confirmed this glitch on their official website, where they then stated

The channel features an original soundbyte on the Wii Menu Title Screen, but the software within contains an explanation of the Song of Heroes glitch, and the option to accept or decline an online update for Skyward Sword that will fix this bug. The channel then informs the user that it is safe to delete The Legend of Zelda: Skyward Sword Save Update Channel from the Wii's system memory after having performed the update.
