    • Pro controller reconnects to computer normally now

    • More gyro fixes (runs at max UDP now - as precise as one can get)
    • Especially noticeable in USB mode

v1

  • Initial release

How to use

  1. Make sure CEMU has at least one input profile set up already (so that CemuHook can feed data into it)
    1. If you don't, go into Input settings (under Options) on Cemu and set the first controller to be a Wii U Gamepad, you can leave the rest of the settings blank (or set the device to your keyboard)
  2. Connect pro controller via bluetooth/usb
  3. Run BetterJoyForCemu.exe
    1. If the controller recongised, the first LED should light up.
    2. If not, see the Problems section.
  4. Start Cemu and ensure CemuHook has the controller selected.
  5. Enable "Also use for buttons/axes"
  6. Please press enter in the console box once you're done with the program - closing it by clicking "x" does not stop the services correctly.

Problems

If the controller does not work after restarting the exe too many times - shut down the exe, disconnect your pro controller and connect it again.

If you get weird lag/stuttering - restart your computer; or try running the program multiple times, closing it properly (by pressing enter) each time.

No joycons detected

If using Bluetooth - see the "How to properly disconnect the controller" section and follow the steps listed there. Then, reconnect the controller.

If using USB - try unplugging the controller and then plugging it back in, making sure to let Windows set it up before launching the program.

Getting stuck at "Using USB" or "Using factory.."

Close the program and then start it again. If it doesn't work, see the "No joycons detected" section and try that.

Feel free to open a new issue if you have any comments or questions.

Connecting and Disconnecting the Controller

Bluetooth Mode

Hold down the small button on the top of the controller for 5 seconds - this puts the controller into broadcasting mode.

Search for it in your bluetooth settings and pair normally.

To disconnect the controller - press down the button once. To reconnect - press any button on your controller.

USB Mode

Plug the controller into your computer.

How to properly disconnect the controller

  3. Click on it and a "Remove" button will be revealed.
  4. Press the "Remove" button

Acknowledgements

A massive thanks goes out to rajkosto for putting up with 17 emails and replying very quickly to my silly queries. The UDP server is also mostly taken from his ScpToolkit repo.

Also I am very grateful to mfosse for pointing me in the right direction and to Looking-Glass without whom I would not be able to figure anything out. (being honest here - the joycon code is his)

A last thanks goes out to dekuNukem for his documentation, especially on the SPI calibration data and the IMU sensor notes!
