I've used the mouse hack to add 2 x USB wheel-mouse spinners to mame. It seemed the PC sometimes lost the location of the mice and it was a pain to get them working again. I re-worked it to use a single mouse with the X axis to one spinner and the y axis to the other. This worked better, but still got issues with the PC 'losing' the mouse. This was probably made worse as I also had a PS2 trackball that was seen as another mouse. Plus, the massively over-populated CP was awful.
My new in-progress build is using an opti-pac to handle all spinners and trackballs on inter-changeable CPs, so will hopefully be more stable.
