Reports ROM4 BAD

Haven't used this PCB set in 10 years but it's almost spotless. I can't figure out which chip is ROM 4. I can't find a layout of the PCB set and I can't really figure it out from the schematics I found. The PCBs do not have any indication either.

Can someone help me figure that out?

I can upload pictures of the 2 PCBs if that's a help.

Update... issue resolved.
In order to figure out which was 'ROM4' I started pulling ROMs and firing up the PCB set. I got to the image below pretty quickly. When I pulled the chip at location 12J I was rewarded with a "ROM3 BAD" (pulling the chips at 9J and 10J caused other issues like frozen graphics, etc... not specific "ROMx BAD" messages.).

So, I reburned the chip at 13J (MAME PP ROM 'pand_j13.cpu') and bingo...
