@donkeykongcab Hey...hope you can help me?
I have a cab set up with a Pi3b + arcadergbpi to gamma...plus an optipac...
I am having trouble getting the inputs working...it looks like you have a similar set up (instead of a trackball and spinner) Im using a wheel and pedal (spinners basically - but optical from an original arcade machine). both register as mouse 2 and mouse 3....but only one at a time appears to work via retroarch...any pointers?
Thanks,
Sean
