I have a Gamecube and apparently, it's unable to read my disc. If the name of the game is required, it's "Pokemon Colleuseum". That was probably a typo. Why is the Gamecube unable to read my disc? Could it be that the Gamecube itself is faulty or that my disc is scratched?

Has it ever worked or did it start recently?

Other than that, is the disc original? If its original and has never worked then maybe the disc is defective, if all games do this it's the console.

It has worked before and the disc is original. Not all games do this but I do have a strange problem with the Legend of Zelda:Twilight Princess: Whenever I turned it off and back on, the gamecube would "think" that there is no disc inside it.

Try cleaning the unit with a laser lens cleaner

It is most likely the disc because if the gamecube will take other games than the disc must be corrupt. If I was you I wouldask for a refund

Well either the game disk is baddly scratched or your gamecubes disk reader is malfunctioning. You should clean the disk and try playing it again or take your cube to the shop to get repaired. But it sounds like it's not the game but the system.
