The Disc Channel is used to allow players to play Wii and GameCube games. Any supported Nintendo optical disc inserted into the console can be played from this channel. The disc channel is used to play the disc versions of Wii games.
If no disc is inserted into the console, the message "Please insert a disc" will be shown on screen. If a disc is inserted into the console, but can't be read, the message "Unable to read the disc. Check the Wii operations manual for help troubleshooting" will appear. In both cases the "Start" button will be grayed out.
Sometimes, if an unreadable disc is inserted (either it’s too dirty or has too much scratches), the screen will turn black with an error message being displayed saying “An error has occurred. Press the Eject button and remove the disc, then turn the Wii console off and refer to the Wii Operations Manual for help troubleshooting.”
If a disc is inserted the picture and banner will change, to one provided by the game. The user will also be able to select the start button as well as the Wii menu button. Selecting the Wii menu button takes you back to channel select. If you press the start button, a message will pop up on to screen to remind the player to wear a strap. Then, the game inserted into the console will start.
