My gamecube will tell me to check the disk right in the middle of a game and ill clean and it will still keep saying it please help:)

Troubleshooting - Multiple Discs

1. Some games may need to be cleaned. Clean each disc with a soft, slightly damp cotton cloth (use water only). Clean them from center towards the edges; do not use a circular motion. DO NOT use paper. Once they are cleaned, dry the disc using a dry portion of the cloth and wiping in the same style as you did to clean the discs. After all of the water is gone, let the discs sit for at least two minutes to completely dry before inserting any of them into the Nintendo GameCube.
   
2. Check for Unlicensed products. Make sure that you're using only licensed products with your Nintendo system. Unlicensed products are not tested for compatibilty and may not work correctly with all games. Try playing the game without the unlicensed accessory.
   
3. Ensure the games are being loaded properly. With the power turned off on the system, replace a Game Disc (printed side up) in the system, press down gently on the Game Disc until it locks on the center hub. Close the Disc Cover and press the power button ON to see if the game comes on the screen. Try this with a few of your games.
