For initial pairing, hold Home + X to put the controller into the correct pairing mode. You can then use Home to pair normally until you pair the controller to a different device.
Known Issues and Quirks:
Atari Jaguar (Jag BT)
Note: due to how some games poll the controller, they aren’t compatible with stock settings. This includes Atari Karts, Missile Command 3D, Myst, and some homebrew games. As a workaround, there’s a controller preset called “Jaguar cycle shift” (see https://blueretro.io/blueretro_presets.html). If you’re using this preset and a RetroHQ GameDrive, D-Pad is mapped to the left analog stick. This issue is being tracked on GitHub.
Some homebrew games do not work with the Jag BT due to their polling rate being much higher than most official games. Unfortunately, I don’t have access to every single homebrew game out there to test. If you’ve found a game that doesn’t work, please contact us and we’ll compile a list. Jaguar homebrew developers, please reach out and we can work together for future releases.
Hitting the reset (“R”) button in some games may cause the clearing of the high score or save data. Most games will prompt you before doing this but one game in particular (Power Drive Rally) clears immediately. This is not a bug but a normal behavior of resetting the ESP32 within the Jag BT. On reset, the ESP32 will toggle it’s GPIOs states registering as a button press to the console.
PC Engine (PCE BT)
Some early PCE BT adapters have a 6 button mode quirk with some PC Engines. This quirk doesn’t effect every PC Engine but if you’re having issues with 6 button games, please watch the fix video here. This is only for the first batch of PCE BT adapters.
Some games (Prince of Persia and Might and Magic) have input mapping issues. The creator of BlueRetro (Darthcloud64) will be looking into this issue further. This issue is being tracked on GitHub.
Xbox One bluetooth controllers need to be updated to the latest firmware to work.
Early Xbox One controllers lacked bluetooth and will not work with the adapter. Here’s how to distinguish between the two controller versions:
Unplugging or plugging in the adapter while the console is on may cause random buttons being pressed. Some consoles, like the Atari Jaguar, have a built in soft reset which can be triggered. This is not a bug but a normal behavior of resetting the ESP32. On reset, the ESP32 will toggle it’s GPIOs states registering as a button press to the console.
