The game I got from XXI21/Brian never makes the "Pssssh! Pssssh!" noise when the player fires. Is this an easy fix? Were there versions where there was no firing noise? Is it maybe just a bad ROM? :confused: Or something I need to look at on the sound card/board?

Is there even a sound card? :rolleyes: I am very unfamiliar with working on arcade games in general*, let alone one of the originals from the 70's, so any help is appreciated.



* Just ask Arcadenut/Brien about my Cap Kit project...
 
Worked fine when I had it... Did you find the volume knob? I had turned down to the lowest setting.

Yeah, I found the potentiometer and got the volume up, but never heard the firing noise... :(

All the other sounds work perfectly, however.

THANKS RedWolf!!!
