Figured it out, thanks anyway. If anyone else buys one of these in the future here's what I did (but I give the caveat that I am no expert or even novice when it comes to these things). In the first picture you see 4 wires going into a plastic plug in this order (top to bottom in the pic) Green, Yellow, Blue, Red. You need to disconnect that plug from the pcb (should just pull off, but be careful) Then I clipped it into two sections cutting between the Yellow and Blue wires. Then I reattached the Green and Yellow in the same way they were, but then reversed the Blue and Red. Seems to have worked. I'll post another pic for reference when I get a chance. now I just have to figure out why the picture scrambles when I launch MAME.
