Blue Retro is a new Bluetooth interface for retro gaming that aims to provide near lag free Bluetooth controller support. In testing DarthCloud64 was able to get some extremely impressive results that make Bluetooth controllers on par and in some cases better than direct 2.4ghz controllers.

This list shows the average latency of tested controllers.

  1. PS4/PS5: ~5.4 ms
  2. XB1: ~8.8 ms
  3. Switch Pro: ~12.4 ms
  4. PS3: ~12.8
  5. WiiU Pro: ~13.2 ms
  6. 8bitdo: ~16.2 ms
  7. Wiimote: ~16.3 ms

The GameCube uses a separate board that has all of the controller ports on it that connects to the main system via a simple ribbon cable.
The new replacement board is built to fit in the same space as the original and offer extra features over the original.


  • Up to 4 Bluetooth controllers can be paired at once.
  • Wired controllers are still usable.
  • When a wired controller is connected it the Bluetooth controllers will move to open ports automatically.
  • LEDs in each port to indicate where a controller is connected
  • Remote power control of the console via macro controls
  • Remote in game reset via macro controls

Remote Power Down

This adapter taps into the incoming power of the GameCube allowing for it to act as a power switch. Using the following button combination the system will power down.

Left Trigger, Right Trigger, D-Pad Right, Center Button Right (Start/Option/etc) and face button down. When released at the same time the macro action will happen.

This powers off the GameCube in the same way that the main power switch would normally power off the system. To wake it back up you just need to power the controller back on, or hit the reset button to wake the console. (Note when powered off in this manner the main power switch will not wake the console only a Bluetooth controller or the reset button will wake it back up)

Reset Button

The reset button on the console has been converted to offer new functionality based on how long you hold the button down. While it is being pressed the front ports will light up to show which state you will be enabling.

Holding for 0-3 seconds will perform the same action as on a stock console, reset.
In this state all four front port LEDs will be solid on

Holding for 4-6 seconds will disconnect all connected Bluetooth controllers
In this state all four front port LEDs will be slowly blinking

Holding for 7-9 seconds will enable pairing mode
In this state all four front port LEDs will be blinking faster

Holding for 10 seconds or more will factory reset to the original firmware and remove any custom configs
In this state all four front port LEDs will be blinking rapidly

When the system is placed in power down mode the reset button will wake it with a single press.

If you power the system off with the main power button, and hold reset while powering on the BlueRetro adapter will be in sleep mode and will not interfere with the console use this in the event that a peripheral is not working nicely with BlueRetro


This product supports the BlueRetro project for continued support and added features as time goes on.
