NET Super Blackjack/Rio de Carnival video output

[ImportantBet]

Hi, does anyone know the pinout for this JST cable that comes out of the sub board (on top front of the machine)?

RGB and Vcc/GND are pretty much givens. Would also like to know the sync type/voltages as well.

I would custom make a new harness, specifically a 8pin JST to DSUB15 cable if possible to record LCD footage.
