Title: Capcom Ghost and Goblins to Jamma Help Post by: DrEric on January 06, 2017, 08:38:17 pm So I had planned on making a GNG cabaret and have it all ready to go...except for the board.
Picked up a Capcom Jamma adapter for GNG from Arcade shop and found a working board set. I then pulled the jamma board I had in there out and plugged it in, made sure keys were right, and parts side was parts side. Powered up and nothing... no audio, video is a no go. VGA board for the LCD has no power. Hmmm...tried another working GNG board and the same adapter, same result. Plug in a jamma board with no adapter and it powers up. Guessing the adapter is grounding out the board? Thoughts/ help please!

Poor Pac. :)
Post a photo. We need to double check the pinout and compare it to what you have.

That's the same pinout I have. I'm guessing the adapter from arcade shop is not right. Jamma cab plays jamma no problem.

Might be worth mapping the adapter connections and see if something's gone awry. Have you thought of making one?
Title: Re: Capcom Ghost and Goblins to Jamma Help Post by: DrEric on January 10, 2017, 09:52:23 pm I made one and it was the same result. Was going at it from the wrong end people. No matter the issue, always start at the beginning.
I started to check the voltages and sure enough the +5 was all over the map fluctuating. My PS was a goner. New PS and the board and vga converter power up = 5 and 12 one he board. :) Now the issue is no signal on the LCD. Although it had been playing when it was playing Jamma Boards. Jamma board tested again and plays. Capcom board is a No Signal. Hmmm All I want is to play my GNG:/ Thoughts?

I've had a 3V drop on a 2 foot cable with cheap and nasty wiring.
Title: Re: Capcom Ghost and Goblins to Jamma Help Post by: DrEric on January 14, 2017, 11:08:00 pm I'll check the vdc from the 5v to the cable to see if we're getting that 5. Like I said, jamma boards play no problem through that harness. Maybe it's the resolution of the LCD?
