I tested the PCB and it works fine with my other Vs. chip sets, but for some reason, when I try to play Vs. Duck Hunt, the video and game work fine, but the sound is stuck on the first start up note. It's really odd.

Does anyone know how to fix an issue like this? Is it an issue with an individual chip in the set?

Thanks!

Any idea what one made it happen ? I have a set of these ROM's with the same issue but I've tried them in two seporate MDS boards and get the same thing.
 
Out of frustration, I just tried re-seating the Duck Hunt chips again and again and it finally worked. It could have been any one of the chips.

I did make sure that all the pins were straight and extended a bit outwards to ensure they would make contact with the sockets. I'm guessing the issue was that one of the pins on one of the chips wasn't making contact.
