trackball delay noticable in Missile Command, Centipede

[Wade]

I also posted this in the "mame command latency" thread but I think they are talking about response to joysticks/keys.


I recently finally installed my trackball after several unsuccessful mouse hacks.   Anyway, immediately I noticed a slight delay on the trackball input in Centipede and Missile Command.  At first, my heart sank because I thought it might be because I used a serial mouse hack instead of PS/2 (performance problem) but now I'm sure it's not that.  I just ran the same games on my notebook with a ps/2 mouse and have the same problem.  Also, the pointer has no delay at all with the same setup but in Windows instead of Mame.

I played both of these games at an arcade recently and there was no delay or buffering at all.  The pointer moved around just like the mouse pointer does in windows.

Is there anything that can be done about this, or it just a mame thing?  Ideas?  I don't think it is a processor issue because both machines are over 1 ghz and run all games I've tried just fine.

Thanks,
Wade

I noticed the same thing in these two games using a USB trackball, until I swapped it out for one that I had broken off every other tab on the encoder wheels. Now they respond great.

Hmmm, well I definitely don't want to go that route (but I would be willing to give it a try if I had a couple of extra wheels around, but I don't).
