I only have a few boards and neither Mr. Driller 2 or Soul Edge use -5V, but there are plenty of JAMMA games that do. It's quite possible to add the missing pin. My cabinet had been converted to Tekken 3, and the operator had added pins for the start buttons as PR just uses button 1 to start. The part that confused me when I first got it was that the start button pins were still wired onto button 1 so that pressing it sent both signals. Adding these pins is really all you need to do to "convert" it as Primal Rage is technically a JAMMA game. As the standard includes -5V, games that don't use it have either no metal contact or a contact that's not connected to any electronics. Capcom's CPS-2 is a good example of this. If you want to compare notes on anything else, just send me a PM. --- End quote --- Ahh the -5 volt. Ok got it. I think it should be pretty straight forward since the cabinet hasn't been touched. Thanks for the tips. I'll be picking up the cab shortly so until then I won't know for sure. |

i think its definately a grounding issue and i sure i can unplug it from the power supply and it will work. in fact when i unplug the 12v/5v plug from the power supply it does stop but then so does the audio. pictures of the cab: i suppose its a case of unplugging wires till it stops |
| Crowquill:
Are you actually using the JAMMA connector then? How are things interfaced? I'm guessing you should be able to disconnect both the 12V and 5V since you're not actually powering a game PCB with it. It's generally considered a bad thing to run the power supply without any load on it. If there's a seperate sound amp in the cabinet, you should be able to run an external power supply for it. I guess I'm just saying it'd help to know the setup a bit more. |

ok the power supply for the cab has two ports one for the monitor and one i have unplugged - for the audio and coin mech and lamp i guess. here is couple of piccies of the ouput you can sort of see where the cable go from the jamma. im going to disconnect some over the weekend and take some more pictures |
