So, I got ahold of an old microsoft mouse. The ones with the potentiometer lookin' things in it.
I'm using it for a stand-alone-spinner-nothing-better-to-do project. I've got it mounted so the knob is directly connected to the shaft of one of the spinners.
My problem is that you have to spin it a whole lot to have the desired effect in mame. Yes, I can adjust the analog settings in mame to make it work better, but I'm looking for a more system wide solution so when I get a real spinner I don't have to go back and change all the settings on all the games I played.
So if you've used one of these types of mouse, or you just have a suggestion on how to accomplish this, please let me know. It's just not the same with a mouse...
