That answers my most important question. That I CAN get it to work.
I'm assuming that as far as windows is concerned they are 1 mouse? So there is a single mouse pointer and the spinner and tball both move it? Which then means in mame I need to be careful not to nudge the trackball when playing arkanoid?
Thanks again,

Yes, there is only one pointer and both devices can move it. And yes, if you're little dork of a cousin/brother/whoever start spinning the trackball while your using the spinner, you will need to throw them out the window

. It'll just be 2 devices fighting for control, but it shouldn't cause any problems (ie crashes, BSOD)
