Blue Retro Internal Adapter with 4 Controller Ports for GameCube - LaserBear

Mod Level Beginner
 We consider this a Beginner Level modification. This mod requires some disassembly/reassembly of the GameCube console to install, but does not require any soldering. Check out the guides below. If you do not feel comfortable doing this mod yourself we offer it for $39.99 HERE or you can bundle the service with the product HERE.


Use modern Bluetooth controllers on your GameCube without the need for a dongle! 

The Blue Retro Internal Adapter is an internal mod that allows you to use a combination of standard and Bluetooth controllers without the need for a dongle. This new board allows for the use of up to 4 connected Bluetooth controllers, and can be mixed and matched with wired controllers on any of the ports for seamless operation. Simply pair your Bluetooth controllers and you're ready to go. Plugging in any standard controllers will automatically move connected Bluetooth controllers to the next available open slot. 

More information can be found in the Install Guide and User Guide linked below.

This GitHub Link has detailed list of compatible controllers and how to pair each type to Blue Retro

  • PlayStation 3 (see pairing guide above)
  • PlayStation 4/5
  • Xbox One/Series X/S
  • Switch Controllers (Only one Switch Controller paired to the console at this time is supported this is a bug that has not been found)
  • 8BitDo (xinput mode)
  • Wii Controllers
  • Generic HID Bluetooth controllers (Note not all controllers will universally work there is the potential you can help us support new devices see the guide above for details)
  • Bluetooth Keyboards (emulate the ASCII Keyboard Controller)

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, Start (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

    An ESSENTIAL GameCube mod

    Posted by Eric on May 18th 2024

    Installation for a novice like me was easy. Laser Bear has a QR code printed on the board that provides great instructions. I synced up my 8bitdo Pro 2 & Xbox Series S controllers with ease, but had issues with the triggers not working. After updating the adapter and watching a video on it, I was able to get all my controllers working with it beautifully! It supports pressure-sensitive triggers and rumble. No more $100 Wavebirds needed!!

    Works with 8BitDo Gbros

    Posted by Shane on Feb 5th 2024

    Amazing! I`ve been in the process of converting all my retro systems to wireless setups. This was a no cut/no solder mod that was easy for a non-techie like me to install. I specifically ordered it to use with the 8BitDo Gbros adapter, and now I`m using my original Gamecube controller wirelessly WITH rumble. 100% recommend.
