Love that background. Just loving it.

 

Graphical mess looks a lot like an adress line is stuck high.

Needs sound on A-Board checked. IIRC sound was working perfectly. [Indeed, sound is perfect]

 

Reseated all (gfx & code) Roms, still graphic glitches. Pain in the ass to reseat that much roms.

next step: label all mask roms, and dump them to compare against mame.

 

 

I have found a .pdf datasheet for the mb834200, within it, it states a am27c400 or a mx27c4100 is pin for pin compatible, Used mx27c4100 – reads fine. VBinDiff works good too.  512K x 8 or 256K x 16 organization(MX27C4100,
ROM pin out compatible

rom 19 and 18: TMS27C010
