Either this channel is present on your system by default, can be downloaded through the Wii Shop Channel, or will be included in a future Wii System Update.
The Disc Channel allows users to play Wii and Nintendo GameCube titles. The Disc Channel displays the name of the Wii title that is present in the drive and plays a sound clip. If a GameCube title is in the drive it displays the GameCube logo and plays the GameCube's default startup sound. However, the channel does not display the game logo and identifying information that the GameCube does.
The Disc Channel is unable to read DVDs or CDs, although Nintendo has announced plans for a DVD enabled Wii. It also treats discs from another region as unreadable. If an unreadable disc is inserted (or if the disc is inserted the wrong way), the channel will display an error message that reads, "Unable to read the disc. Check the Wii Operations Manual for help troubleshooting."
If no disc is inserted in the drive, the channel displays the image at the right. When a GameCube or Wii disc is inserted into the drive, the pictures of both discs spin until the type of disk is recognized. Once the disc type is recognized, the extra disc fades out and the recognized disc descends into a slot.
This is the only channel that cannot be moved. It is always in the upper left corner.
