Recently acquired a copy of Nightmare in the Dark. The game fires up, but the entire screen is glitchy. You can see things moving and animated, but can't make out any of the sprites or graphics (http://i.imgur.com/rvIuzS2.jpg). Tried cleaning the pins, but no luck.
Looking at the boards, I didn't see any obvious signs of damage or corrosion or broken traces (http://imgur.com/a/CBGze).
I found this thread for an issue that sounds very similar with Metal Slug 5.
So first, does it seem likely that the problem is a bad CMC chip?
Second, if it is a bad CMC chip, is my understanding correct that I would want to try and get a donor board from another game that had the same CHA board and a working CMC chip, then transplant the three game chips from my bad CHA board to the good donor board?
