Got one with a couple graphic glitches.

Roms - Verified
QFPs - Reflowed and pins checked
Long ROM Test - Good to go

During the start of the first stage if you look at the mountains you see it flashing a bit, also during the attract where there is a star falling, I can see a line missing on the upper half of the star (vertical).

I also see some kind of ghosting. When a character jumps up and down I can see a shadow running from left to right.

I'm guessing it could be RAM going bad, maybe the 2018s.

Anyone got a schematic? Didn't see one at arc.
 
Well the flashing problem turned out to be some bad 6116 RAM near the JAMMA edge. Now I need to tackle what is causing the vertical line glitches. Maybe a bad 245 or something. Gotta probe it again.
 
245s don't look suspect and 64kbit SRAM looks fine. How does /CE2 work or the 64kbit SRAM? Is it even active on this boardset?
