Advice on how hard this would be to convert to MAME
markronz:
Thank you, that link is huge! I read that thread. Very interesting.
So let me see if I've got this correct. The "Jamma Edge". So this plugs into the Jamma harness right? I know that much at least, that there's a harness. So I plug that in there. Those just work then. No extra wiring, to the existing controls, needed right? Then the other connectors -- for "Player 1" and "Player 2" in your picture, those are for use on ADDITIONAL buttons, right?
What about the VGA port there. It says its going to the PC Screen or Arcade screen. I'm confused about this, since I have no knowledge of arcade monitors either. So if the one VGA cord from the arcade monitor goes here, what plugs into the computer? Sorry, just not sure what that looks like yet with the monitor...
Nephasth:
The VGA port is input coming from the computer. The J-Pac outputs video to the arcade monitor through the JAMMA harness.
bkenobi:
Correct me if I'm wrong (never worked on JAMMA stuff), but the display is fed through the JAMMA connector.
So, to get things working should be pretty simple. Plug the card into the JAMMA connector. If you have more buttons that required a kick harness, you wire those through the P1 and P2 button area. Then, plug the VGA, USB/keyboard/etc ports into the PC (and optipac/ipac/keyboard/etc). Seems pretty simple.
EDIT: Woops, Nephasth beat me...
markronz:
Ok that makes much more sense. I was not aware that the display was also through the harness. That answers that. But I still need the Arcade VGA card, even though my video is being passed through the JPac, right? If so, would I still need Soft 15 as well, even though I have a JPac and Arcade VGA?
Also, I assume the speakers work in the same way? That the sound is passed to the speakers through the Jpac?
Nephasth:
You still need an ArcadeVGA (or some other VGA to CGA adapter), yes. You shouldn't need soft 15 if you use an ArcadeVGA.
As far as speakers, from Ultimarc:
