Hello all, arcade noob here. I have read some of the other threads regarding the Joust 131 issues with and have hit a wall. I have the 131 error and the game is stuck in a loop. I see activity on the chips and get the sawtooth patten on the screen and it just keeps trying to reboot. Voltages are ok and all the RAM and Decoder ROMS are pulsing according to the logic probe. Memory had been upgraded to the 4164 chips and +5volt harness change was done. The game was working fine and one day just stopped. Any other thoughts as to what could be happening?
Thanks
DW
