I had a friend of mine over who has a real centipede machine and he noticed that the trackball did not respond to movement as quickly as his authentic did. Once it was spinning he felt like the shooter moved at the same speed but there was a lag on "take off". I am using an optipac with an older wico trackball. The pickups are the non active style. I have a couple of questions for the spinner guru's on this:
1) what is the limitation as far as optical input? is it in the interface or in the mouse port(serial)? Is there a faster way? (usb pehaps)
2) what causes backspin when mame is set too sensitively? is it the software or the hardware? (again is ther a better way to interface?) I have noticed that i cannot get my spinner to backspin in windows no matter how hard i spin it but in mame if i turn up the sensitivity it will back spin. I would think that would indicate software but i am not sure.
3) has anyone had any luck using 2 trackballs in mame 32? the optipac has 2 serial outputs but my understanding is that windows only supports 1. is ther another way to interface trackball 2? (usb again?)
Thanks in advance for the help.
