The problem is i can't match the roms to understand how it works.
The 1mb roms are halfed, but when dumping then comparing, i find only IC35 is first half of 42 (on original dump), but nothing for the rest of the 42, and all of 43, 44, and 45.
Basically this is what matched for now :
(Right is korea, left is world) IC1 = IC9, IC2 = IC10, IC10 = IC8, IC16 = IC11, IC17 = IC12, IC35= first half of IC42, IC36 = IC33, IC37 = IC34, IC48 = IC32 and IC49 = IC31.
No match for IC 24, 31, 32, 33, 34, 38, 44, 45 and 47 on the korean?
Matbe this will help someone someday.
I think this game romboard is either another Korean revision or a bootleg.
Mother board is an original A-B board though.
