PCB traces are excellent
Monday i will read both roms and compare it.
I had cards as a gift , so I do not know if it's a defect .
That's why I suggested comparing your two ROM1 chip dumps.
It is almost impossible
ROM1 chips would malfunction in exactly
the same way yielding exactly
the same data dump.
It doesn't rule out a defect elsewhere on the board/logic ICs, but it does let you rule out ROM1.
Sound are only on rom 1 ?
I don't know for sure, but the dump documentation indicates that the Z-80 handles the audio for the board.
ROM1 is the only one near the Z-80, so it is probably the only one with audio.
It's possible to have binary file for Rom1 and re-write it?
If the ROM isn't damaged/corrupted, it won't do any good to rewrite it or burn a new one for the same reason that copy+paste =/= spell-check.
The problem is almost certainly an inherent mnufacturer's flaw in your ***bootleg
*** board caused by imperfect reverse-engineering of the original Capcom board/logic/ROMs.
One possible way to verify this is to find the dumped ROMs and run them in the FB Alpha 0.2.97.39 emulator.
The only drawback is that the PLDs are listed here
as "read protected" -- not sure if that would result in sound emulation working differently from the original board.
Another way is to contact the guys who dumped the ROMs from this board and ask them if the combo in question triggers a sound on their board.
