This is a Wavebird controller for the GameCube. I bought it several years ago to breed Pokémon, but I left it unattended carelessly. When I tried to check its operation for the listing, the controller wouldn't turn on even with batteries inserted. The spring on the left side of the battery compartment is stiff, likely due to battery leakage. Therefore, I cannot confirm the receiver's operation, and it's unknown if it can receive signals from other controllers. Due to the above reasons, this is being sold as junk. Please purchase only if you can repair it yourself or if you are interested in the receiver.
