IIRC, the early CAVE games need you to unplug a sync cable at the bottom of the cabinet (near the floor somewhere). I'm sure someone else can give a better description.

It might also be that the PSU is acting up unless you have a stepdown that delivers 100V and not 110V to it. I think. I've never owned an AWSD, so I haven't been in this situation personally.
Check your JAMMA harness with a multimeter, specifically all the voltages (separately). There's an issue with Egret II where one of the +5V doesn't actually provide +5V, and it causes issues with certain PCBs, like Moonwalker. Probably doesn't apply to your cab but worth a look.

I do, and the PCB works wonderfully in the other cab.

I just checked all of the voltages at the harness, and they are right where they should be.

Can we get a pic of the jamma edge connector of the PCB and a pic of your cabs jamma connector, please.
I tend to agree with you, though everything looks to be in line to my amateur eye. At least at the jamma end of the video ground. Pics:

To me, this implies that the video ground on my jamma harness is broken somewhere. Am I correct? Any tips on how I might go about chasing this down?
I'd say: No. Some boards just don't combine the gnd's. had the same issue on a Carrier Air Wing boot on my Astro City. It worked flawlessly on my old woody jamma cab.
Good work btw feels nice to fix boards, right?
