That would be perfect for an idea I had about mounting an optical mouse underneath a CP, upsidedown so the laser points up, and then using a trackball like the one listed mounted in a similar fashion. That would make for a super cheap setup. All you'd have to do is invert the mouse controls in windows and thats it. No additional hardware. What your computer sees really is the mouse.

I came up with this idea after thinking how I could modift an optical mouse to work with trackball games. Since trackballs today still use the same principles as mouses, only bigger, I thought, why hasnt anyone designed a trackball with colored, swirled, dotted, or textured image trackballs that would not spin rollers, but rather, trick the mouse into thinking that the ball was actually a "surface" it was moving over.

I should patent that,

thought you guys might find this interesting if you havent seen it.. havent researched it much or read all the detail but apparently it works pretty well... these guys use it for FPS games but its interesting and it should work with Mame pretty well..

Actually.. I just noticed a custom USB interface PCB that he uses for connecting all the pots and switches.. hmm that might be cool for some Maming as well... I wonder if theres guys are familiar with BYOAC?

Think about what you just asked.
If the trackball DIDN'T spin the rollers, it wouldn't MOVE.
If the trackball doesn't move, and the optical sensors don't move,  what DOES move.

If you're going to have to have the ball move anyway, why go to the expense and frailty of an optical setup, when you can just put an encoder on the end of the shaft that's already moving anyway.
