TLDR: After having owned the controller for a while I noticed that every time you install a new kernel update the fixes are undone again, and have to be re-applied. I also discovered that the controller UID is the same for all SN30 Pro+ controllers. So I’ve made the following script that fixes everything automatically instead. Save it somewhere, check that the config file paths are correct, install xpadneo using the github instructions, then run the script as root.

Original post follows:
I recently bought an 8BitDo SN30 Pro+ since my old gamepad was an ancient Logitech Dual Action. I wanted a gamepad that was wireless as well as having support for XInput. When I heard about the SN30 Pro+ I couldn’t contain myself, so I went and bought it the same day after reading a bit about it and how it works on Linux. It’s not officially supported, and there wasn’t really much definitive information regarding Linux compatibility, other than that the older SN30 Pro worked fine and it works on the raspberry pi. So I just took a gamble and bought it.
