Well, I followed the guide located here: https://www.petrockblock.com/forums/topic/updated-for-2-2-step-by-step-guide/
and when I got to the part you configure the joystick (vintage SNES controller), IT WORKED! I was able to play Donkey Kong Country with the first controller!
But the problem is, I can’t configure the second joystick (vintage SNES controller). When I type in the same command I used to configure the first controller, it says “Couldn’t open joystick #2”.
What can I do?
