BlueRetro RSBL-231149 adapter for GameCube: a modern Bluetooth controller on the original console
Original GameCube controllers are becoming rare and their sticks wear out. This BlueRetro adapter by RetroScaler (reference RSBL-231149) plugs in place of the wired controller on a GameCube and receives a modern Bluetooth controller: PS3, PS4, PS5, Switch Pro, Wii Remote or 8BitDo.
What it does
- BlueRetro firmware: free (open source) firmware on an ESP32 chip, which recognises a wide list of Bluetooth controllers and keeps evolving.
- Update via USB-C: the adapter's USB-C port is used to install new firmware versions.
- Button remapping: button assignment is set from the BlueRetro web interface, in a browser that supports Web Bluetooth.
- No work on the console: plugs into the controller port, without disassembly or soldering.
What it doesn't do
- It only handles Bluetooth controllers: a controller with a 2.4 GHz USB dongle, or a first-generation Xbox One controller without Bluetooth, will not connect.
- The Switch Pro controller's triggers are digital: games that use the progressive travel of the GameCube's L and R triggers lose that nuance with it.
- The PS3 controller requires an additional pairing step, via USB cable from a computer.
- Bluetooth adds latency: low, but higher than that of a wired controller.
- It does not replace a bongo, a steering wheel or a WaveBird controller.
Compatibility
Console: GameCube, all regions, on the controller port. Bluetooth controllers listed by the manufacturer: PS3, PS4, PS5, Switch Pro, Wii Remote and 8BitDo. Use on the GameCube ports of a Wii is not covered by this page, nor are controllers with a USB receiver.
Skill level required
Beginner. Plug the adapter into the controller port, put the controller in pairing mode, and the connection is established. Firmware updates and remapping are done from a computer, with a USB-C cable. No tools, no disassembly, no soldering.

The job: plug in, pair, play
You remove the wired controller, plug the adapter in its place and put the Bluetooth controller in pairing mode. The GameCube receives the commands as if from an original controller. You play without a cable across the living room, with a modern controller, without having to hunt down a vintage controller that has become rare and is often worn.
The part: BlueRetro, a free firmware
BlueRetro is open source firmware that runs on an ESP32 chip. RetroScaler builds it into a housing with a GameCube connector, with a USB-C port for updates. Each firmware version can extend the list of recognised controllers and refine the settings, without changing anything on the console side.
Support: choosing the right controller
For games that rely on trigger pressure, choose a controller with analogue triggers, such as the PS4 or PS5 controller. Also check that it is indeed Bluetooth: a model with a USB dongle will not connect. If in doubt about pairing or remapping, our customer service replies within 1 business day.

Frequently Asked Questions
🔌 Do I need to open the console?
No. The adapter plugs into the GameCube's controller port, in place of the wired controller. No disassembly, no soldering.
🎮 Which controllers can I use?
Bluetooth controllers: PS3, PS4, PS5, Switch Pro, Wii Remote and 8BitDo. The PS3 controller requires prior pairing via USB cable from a computer.
🕹️ Are the analogue triggers retained?
With a controller that has analogue triggers, such as the PS4 or PS5 controller, yes. With a Switch Pro controller, whose triggers are digital, the progressive travel is lost.
🔄 How do I update the firmware?
Through the adapter's USB-C port, from a computer. An update can extend the list of recognised controllers.
⌨️ Can I change the button assignment?
Yes, from the BlueRetro web interface, in a browser that supports Web Bluetooth.

Delivery in 10 to 18 days, dispatched within 3 to 5 days.
🛡️ Which guarantee applies?

Why buy here rather than on a marketplace
It is a fair question. Here is the answer, straight.
Every listing is checked before publication: real compatibility, material, dimensions, box contents. Many models never make it into the catalogue.
A question about compatibility, a fit problem, a return: you write, a human replies within 1 business day. In French.
The 2-year legal warranty of conformity is handled by us — not by a form on the other side of the world. And 14 days to change your mind, with no need to justify yourself.
We do not claim to be the cheapest. We claim that you will know exactly what you are buying before you pay.
