Invert Trackball Directions

Looks like I accidentally installed the trackball upside down.  :banghead:

Instead of having to undo the mounting brackets and cutting a new hole for wiring, is there a way I can just invert the trackball directions in windows or mame?

 

PL1:

Swapping the two data lines on each axis should do it IIRC.

X1<==>X2

Y1<==>Y2

Leave the 5v and ground wires as is.

Sorry, I should have mentioned that it is connected through PS2.  I guess my only option is to un-mount and start drilling.   :angry:

Thanks though PL1

PL1:

It still uses opto boards, or does it have the encoder on the same PCB?

I'm really not sure what any of that means?  Sorry, I'm new to most of this stuff.
