How to rewire a trackball to rotate it 90 degrees - fixed
diverdown:
:banghead:
I have just plugged in my CP and found I have installed my trackball 90 degrees out. :banghead: :banghead: :banghead: :banghead: :banghead: :banghead: :banghead:
I have wired up 4 player everything with LEDs to all buttons and a spinner so I CANT remove the trackball and spin it around.
What do I have to do to make this right in Windows and mame.
It is a betson trackball from GGG.
I believe if i swap the sensor boards around inside and then swap the yellow green wires over this may work.
Or is there a simpler way of swapping the wires around that go to the optiwiz?
Now to try to get the trackball off the mounting plate
Any ideas?
DaOld Man:
I think you can just swap the wires around. Just dont touch the reds and blacks.
I have a betson and it's not marked as to which way is "up", so I dont think it really matters, however on a Happ it is marked, (arrow pointing to monitor).
I would try the wire swap before re-designing my CP.

Funny you should ask.. i just went through this same thing
Seems the Green/Yellow wires control one mouse axis, and the Blue/Brown control the other. After talking with Randy, it appears very important to have a main roller positioned so it's facing the bottom of your monitor once mounted (for fast spin games). My process involved rotation my installation by 180 degree to place a roller at the top, then swapping the circuit board positions inside the trackball (they just pop out with slight pressure sideways). Then after checking my axes.. I had to snip the blue/brown wires and cross them to reverse the polarity.
It was pretty easy, and took about 10 minutes of figuring out "which was was up". Check out my link, feel free to ask if you have problems. It's pretty easy, just annoying.

Does the optiwiz present as a mouse to windows? I swore there was something in accessibility for re-orienting your mouse...

Even if you do find a software fix.. if you do not have a roller at the top of the trackball, it spins very differently when trying to get it to spin up very quickly. Give it a try and if that doesn't bother you, this fix might be for you as well.
