Insidegadgets GBA TRX Cart And GameCube Receiver (wireless GameCube Controller)

This is a 2-piece set. 1 Insidegadgets GBA trx cart. This cartridge turns your gameboy advance into a wireless controller for the GameCube. 1 Insidegadgets GBA trx cart receiver. This receiver plugs into the GameCube controller port and acts as the wireless dongle. No pairing necessary. It’s not Bluetooth. I think it’s 2.4 ghz. *I put the receiver into an old Madcatz dongle so that it’s contained in a case/housing. Both items are extensively tested and working great. All buttons work. I can’t tell if there’s any input lag. If there is, it’s not noticeable. This is best used to play Gameboy/GBC/GBA on the GameCube. Let me know if you have any questions.
