BlueRetro adapter for Saturn: a modern Bluetooth controller on the original console
Original Saturn controllers are well liked, but their cable is short and units in good condition are getting rare. This BlueRetro adapter by RetroScaler (reference RSBL-231105) plugs in place of the wired controller on a Saturn and receives a modern Bluetooth controller: PS4, PS5, Switch Pro, Joy-Con or Xbox One S.
What it does
- BlueRetro firmware: free (open source) firmware on an ESP32 chip, which recognises a wide list of Bluetooth controllers and can be updated.
- Button remapping: button assignment is set from the BlueRetro web interface, in a browser that supports Web Bluetooth.
- Three colours: grey, blue or black.
- 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.
- A modern controller does not have the six face buttons of the Saturn controller: remapping helps you find your bearings.
- Bluetooth adds latency: low, but higher than that of a wired controller.
- It does not replace a light gun or a steering wheel.
Compatibility
Console: Saturn, on the controller port. Bluetooth controllers listed by the manufacturer: PS4, PS5, Switch Pro, Joy-Con and Xbox One S. Not covered: other consoles, controllers with a USB receiver and accessories that are not controllers.
Skill level required
Beginner. Plug the adapter into the controller port, put the controller in pairing mode, and the connection is established. Remapping is set from a computer or phone that supports Web Bluetooth. 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 Saturn receives the commands as if from an original controller. You play from the sofa, without a short cable forcing you to sit at the foot of the TV, and without wearing out a vintage controller that has become valuable.
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 Saturn connector, in three colours. The benefit lies in the community: the recognised controllers and settings grow with each version, and remapping lets you reposition the six buttons.
Support: choosing the right controller
For the Saturn, a controller with six face buttons recreates the original layout; otherwise, remapping bridges the gap. 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.

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.
