You sure some settings in MAME didn't get changed?

Good point, does it backspin in Windows?

Also worth checking for binding rollers, sometimes the ball slipping on the rollers can cause this.

It has been mentioned here that the Happ USB trackball suffers from backspin when spun fast from new. Thats another issue though.

Based on everything I have been reading about the issue, my guess is that the IR LED's in the opto-sensors dim over time.  They could have been over-driven in the earlier design, or just didn't live up to their longevity specs.  Most of the issues I've seen posted seem to pop up after a certain time period, and get progressively worse.

Not sure how this could be.  Choppy or singular axis motion, but not "backspin".  Can you elaborate?

FWIW (and it may not be worth much), I had a non-USB Happ trackball exhibit these same symptoms today (PS died a while back in the machine and I only replaced it last night) and replacing the optic boards solved the problem in that specific case.

I have a Happ trackball with USB interface, but it has never posed any problems with respect to backspin.

Thanks for all of the advice! Randy, yes it is also displaying these symptoms in Windows. What I am experiencing is best explained using World Class Bowling as a reference. When the TB is spun fast as in World Class Bowling the gameplay will hesitate as the trackball is spinning like mad and then suddenly the game will pick up the movement, but will result usually as a slow take off and will result as a foul.

Andy thank you for the fantastic offer!  I will check with Happ and see what the cost of replacement USB boards is and let you know. Does anyone know the part # on the replacement USB boards?

Binding rollers would not cause backspin but sometimes the problem is not described 100% accurately. It would cause hesitation, which the OP does seem to have.
