It may be a coincidence that the HAPP TB started giving you problems at the same time you decided to switch to a different OS.  Backspin is exactly the issue the HAPP TB's exhibit when the opto-sensors start to give out.  If you have been able to boost the poll rate and still see the problem with only the trackball, then it must be the TB that is the problem.  With the original, very low resolution encoders, it's nearly impossible to get backspin on the trackball without some other processing issue at play.

Bender,

6 is the "arcade perfect" setting for the TurboTwist 2 and Tempest.  For some reason, the Atari titles which use optical controls from that time period are very touchy.  I don't know whether it is spotty emulation, or what the situation is there, but if you check out the trackball action on Centipede, you'll see similar weirdness.  But at 6 on Tempest, you should have a "very close to the original" experience.

Agreed! Tempest works fantastic now!

What settings would you suggest for atari trackball games?

That's a tough one because it depends on the controller being used and the title in question.  Honestly, I haven't found one that I really like for Centipede because of the way it feels compared to the original machines.  Also, I don't think the later Atari trackball titles suffer from the same "weirdness."

Yeah agreed.  I'd guess Centipede polls the TB faster than mame, or multiplexes (related but not same thing).  The arcade moves a lot faster than mame.

Derrick Renaud:
This whole Vista 64 SP1 locked at 125Hz poll rate blows.   :badmood:  I wonder if you can still set the PS2 rate to 200Hz from the default rate of 120Hz.  XP allowed you to set it in the mouse's properties in Device Manager.

As I have explained in the past, 200Hz is the minimum barely useable rate.  Games like Tempest poll at 240Hz.  I think Centipede also does, but can't remember.  They need to poll quick because the games only use a 4 bit counter for +7/-8 change.  Anything larger in a sample period will roll over (backspin).

I have Vista in Test mode and have also tried F8-allow unsigned driver.  hisusbf.sys shows up in the device manager under Human interface devices for the trackball when filter is selected.  But no matter what rate I select, it just uses 125Hz.

So now Tempest backspins even when set to a MAME sensitivity of 6.  It is mostly playable, unless you free spin it.  I always do this at the end of the first levels.  But now you can't.

 :angry:

Looks like I'm going back to XP.  The extra speed of using MAME64 is of no use, if the controls are unresponsive.

500Hz is really needed to smooth out what is being sent to MAME.  Someone will have to dig up the old post where I explained all this.
