Hello Guys,

I found a copy of this game that apparently has some issues with the audio volume.
On this video you can cleary hear the problem on game logo.

When I opened it, I found a complete mess SNK made, and I think something's wrong.
the card looks like an authentic hand-made paintin :D

On this side the capacitor 151 and the resistor seem to be missing.

On the back of the board there are still soldered remains of a pin of something that was once there

what do you say guys, am I getting closer to the problem?
am I missing something else?
 
The front looks (mostly) like the board scans at mvs-scans, but none of the scans there have the resistors on the back.

What an ugly looking pair of boards!
 
No, its not work even with 151 capacitor, its do not seems a PCM or V eprom corrupted.
I have do not tested it at moment, because of pins of it.

SOLVED :thumbsup: Here the problem, broken GND point.
This solder point was broken.

At this point i'm not sure if i have to add 151 cap, need also a resistor ?
Can some one take a pic or see on other board please ??(
