Re: Omega Race random Vectors when shooting.

Well there was minimal acid damage to PR1 area just below the battery. Those
look like the ram select circuits.

All ram has been re-socketed, and any residual acid damage cleaned up. The
Fluke isn't reporting any ram problems with the long test.

The area in the video is where the problem really shows up. During a normal
game, there are slight glitches in the middle box area.

Roms have been replaced, and custom chips checked and cleaned.

So I'm at a loss atm.

Will try Googling asteroids problems and see what I find, but so far nothing
with the description givin.
