Motion evdev

These instruction are made with a Nintendo Pro controller and Joy-Cons. While the overall process will be the same the motion axis may not match those found on a Sony DualShock 4.


 * Recent dolphin version (do not use 5.0 stable!)
 * HID Nintendo kernel driver (dkms https://github.com/nicman23/dkms-hid-nintendo)
 * Switch pro or Joy-Con.

The HID Nintendo kernel driver exposes 2 evdev devices, one for the buttons and another (IMU) for the accelerators/gyroscopes. Do note that Joy-Cons will have 2 devices each (4 in total).

It took me a bit of time figuring out which axis corresponds with the right motion control in dolphin.

As the default buttons are all wrong reset all buttons in the Wii Remote configuration. To configure the motion controls you have to use the advanced config window. Right click on each motion button in the Wii Remote configure window. Select the appropriate IMU device at the top in the device selection.



Select the corresponding Accel or Gyro axis, select it and click ok. For example for "Accel Up" in dolphin you need to select "Accel Z+". The end result should look like below.



Repeat this for every motion.
