So I tried creating my own controller.ini file for my Sn30pro plus using HID test and the controller is being recognized by HID test. However, HID test is failing to load the config and the controller is not working in nintendont. I attached the controller.ini below.
I tried:
usb:/controller.ini
usb:/controllers/VID_PID.ini
Neither of these worked.
