The Retro Receiver is a Bluetooth® receiver that you plug into your original SNES. It allows you to play your SNES wirelessly with any original SNES or SFC model and even other aftermarket SNES/SFC systems. 

With the Retro Receiver, not only can you play your SNES wirelessly with any 8BitDo Bluetooth® controller or arcade stick: but you can even use wireless next gen controllers, too.
*Bluetooth controllers supported only.

Note: Xbox Bluetooth controllers on the latest firmware released in Sep, 2021 are NOT supported any longer, due to their bluetooth change from Classic to BLE.
