I'll add my comments. Picked one up thinking if the controls worked, I'd just plug the VGA to my MS2930 and call it good.
I'm on the rev b board that has the CPS1 kick on it.
However, my P1 at first wouldn't even work but eventually got it working. Tried swapping cables and checking connections on the cables and traces, nothing. Might be an issue with the Pi microcontroller chip. But I found if I reset the console it works on second boot? So who knows, but works and won't drop once it's working.
For controls, only got the stick and 1,2,3,4 and 5 to work initially. But I did noticed on the board there's a pad marked for a diode to the CPS kick that is unpopulated. If you bridge those with some wire, it connects the b6 to the CHAMMA edge and it works with a JAMMA to CHAMMA adapter that has a CPS2 kick connector on it. I included a pic and circled them in green. With that, all 6 buttons, directions and start were working for both players with the adapter. If you have a CPS1 connector you wouldn't need to bridge those, but would need to be done for anyone using the CHAMMA edge.
As others stated, the RGB is super dim, even with the pots all the way up. No way to fix that unless they put an RGB amp in the board. Would have been nice if there was a switch to toggle between 0.7V and 3.2V video levels with an amp.
Sound was distorted and seemed to cut some channels but saw that's from plugging L and R together. Make sure you have games set to mono and only plug in one channel.
I just wish my P1 would work 100%, but seems turn it off and on again is a fix. It's unfortunate that the RGB is just too dim as it's consumer levels vs arcade monitor levels. But in my case I've got a tri-sync so I'll just run the game through VGA at 31kHz as the brightness was good as that looks for the lower voltage.
