Nice that you used an original pcb.
Any photo's of how you wired everything up on the inside?
Did you use a supergun or made all the wiring yourself?
Very curious.
It is a bit of mess inside right now

I have to take some time to make things clean.
Basically, I used a converter board that connects to the edge connector of the board.
It is used to convert the board to jamma (which means sound amplification, and rgb
inversion).
Then I made the wiring from scratch, not using a supergun. There is a standard arcade psu.
Also I made myself a RGS to SCART adapter so I can connect directly to the tv.
For controls, I used the fact that the control panel plugs directly onto the game board
(there is a connector for it). I wired the coin switch to the service switch so it is easier
to add credits to play. Also because there is no free play for this game. I tried the free play
mod roms floating around on the net for this game, but couldn't make them work.
I also added an adapter board which allows connecting the control panel to the jamma connector,
so I can also plug other vertical games and play them.
