I'm pretty sure it's either the jamma harness or converter you are using. I've had sound issues on MK boards as well due to the harness not being wired correctly for that -5v that the sound needs. Also, those cheap harnesses seem to have a different gauge and feel to the wire....it feels cheap...
Yes, I did manage to fix this. My issue turned out to be a result of me using a cheap jamma harness. I ended up buying one from twisted quarter and boom the problem was solved! Those converters can have issues, so maybe building a jamma setup without that converter might be worth a try. Hope...
I'm glad I found this! I absolutely love NARC and would like to see it run on Y unit hardware for other people to enjoy....especially since that would make it a JAMMA game. I have an actual working NARC cabinet and would be curious to see the game in standard res!
Hello,
I was originally going to try and purchase a Revolution X cab and have these boards as backup but I will be taking another route...probably going to make a MAME cab with the lightgun shooters. Not sure what these are worth and all boards untested. You get the game manual, two main PCBs...
