sf2cejc Street Fighter II‘: Champion Edition (Japan 920803)
Minor graphical glitching.
Zeros on Zangief’s fence, „PuSh 1P StArT, CrEdIt“, Checkerboard on Guile’s sunset.
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,
