Well, I'm FINALLY closing in on getting my cp done after about 2 years of this project.

Anyway, I have an electric-ice trackball installed, and one issue I have is in plain windows XP (haven't even gotten to Mame) is that the Y axis seems to be inverted!?!?
At first I thought I had the trackball rotated 90, but there is no direction that I could orient the trackball to get it to roll up = mouse up on screen and roll right = mouse right on screen. I don't believe it's simple as switching board locations.
I don't mind too much if I have to attack this with a soldering iron - although I suspect that is a solution - but for what I paid on these I hope not! I was also thinking that it may be possible to change the settings in XP (I couldn't find the place though), but I don't want to bugger up any other mice I may connect. I do connect to my arcade machine via Remote Desktop/vnc so I don't want to have to invert my mouse in that situation.
Could there be a jumper on the bottom I can change? Anyone else have this issue or ideas?
For reference, on the y axis the molex plug is wired:
Top
------Blue-> Board
------Red-> Board
------Black-> Board
------Brown-> Board
Bottom
