Yeah that would be great. Now I also have an SF30 Pro and Don know how to use it.
The SF30 Pro is quite easy. You can start it up in different modes by holding Start+A, B, X or Y. IIRC Start+A lets it be detected automatically by HID to Vpad as a Dual Shock / PlayStation controller. I have had trouble with the Switch mode in HID to Vpad (buttons are assigned wrong / seem to be held down). Try different modes until one works.
To make your config file, you will need HID Test, which is linked to from page 5d [Adding new devices] of the wiki, and I think is also in the Homebrew App Store. And you might as well start by downloading a random config file from the repository (should be linked from the wiki) to use as a base - the Core(plus) one would do, as it uses the format of numbers you’ll see in HID-Test (and will hopefully already be all correct, as ooLIAMoo suggested).
Plug in your controller and open up HID Test. You will see a black screen with white text.
Make a note of what it says next to vid and pid and put them in instead of the numbers at the top of the config file you downloaded, if they don’t already match.
Now you need to press each button on the controller and look at the number that changes at the bottom of the screen. The bottom number that changes goes at the end of the corresponding line in the config file (VPAD_BUTTON_whatever = 0x[], 0x[]), after the comma and second 0x. The number in the row above (labelled Pos) goes after the first 0x.
Getting the d-pad and sticks sorted is a little bit more complicated, and I haven’t had to change them myself. The wiki explains it so I probably could make one if I needed to. Let me know how you get on, and whether you want me to break down those steps too.
Good luck : )
