This isn't right... correct? Seems negative to me. Or is it just me?

I'm not sure it's inverted, as Bentley looks like he's the right color...here's a screenshot from MAME:

Bentley looks good but your missing red from the castles and crystals. Maybe a color prom on the board? I would try reseating the chips.
 
Tried reseating chips, now I get this:

Cleaned all the legs really good, no change. :/

Edit: and now my multimeter isn't working. Dumb. I'll have to go buff discs and hope Jeff F comes and and points out the obvious and stupid thing I am overlooking.

Finally had some time to look at this more today.

I got it to boot again, now I get this:

I swapped 4a and 4b and the problem followed. So I guess I have an answer.

My question is this: why does it say the ram and roms are ok but I get this when I select the test eerom option?

4a and 4b are rams (2212). I'm sure it's something that makes sense to someone but I know nothing of this...

Only thing is it says they are used for saving the high scores and settings so I wouldn't hold my breath it'll fix the graphic issue... but then again... you may have fixed that with reseating the chips(but zapped the RAM in the process). :dunno:

Wish I had a game that had a 2212 in it for ya...

Nope, colors are still the same. The game actually plays as it is (was) again. Just screwy colors.

+1 The color prom is at location 10K but it is not socketed, at least not on the pcbs I've worked on. Could also be the color ram at 10R. If not those I would go for the 153's at 10L and 10M.

Mine passes the EEROM test but won't save the high scores. The self-tests aren't that thorough apparently.

I agree with the previous poster, but I would also add the LS273 at 10N as a remote possibility.
