I just got 2 x Tekken 3 boards Namco 12, and trying to run through the JAMMA edge.

Both loop on JVS check counter and doesn't move forward.

Changing the switches dont work.


Am I missing something? :/
 
Probably won't make any difference, but there's a battery on the main board. You could try removing it.
 
Had exactly the same symptom once...

PCB was in a boot looping...

After changing the work RAM and re-flashing the game failed, the culprit turned out to be a corroded track...

May be this helps...

Good luck
 
Thanks, in my case it worked in my cabinate which has an arcade power supply with voltage cranked up a bit, but that problematic loop occurred on my Retroelektronik Supergun setup with a cooler master 500WATT ATX PSU. My supergun isn't really as good as the HAS/Sentinel which are available here so most probably the Namco System 12 wasnt getting enough voltage to run properly.
