This is the Dongle for the white i.glow Dreamgear Wireless Controller for gamecube. This was paired with the White controller (with blue LED lights) - I'm unsure if it will sync and work with the Black controller because this was only able to be tested with a white controller (not included)
If you have any questions about this dongle receiver, feel free to send me a message!
The original controller was designed as a way to play gamecube games on the Wii wirelessly with a gamecube controller.
