A source recording from the bootleg would be beneficial here.

there is no need of a recording since the pcb behaves identical to the original, same samples triggered in same situations.
I corrected the clock speeds which were guessed before

I had a recording from a real bootleg PCB that exhibited the same 'problem' as MAME before, so we now have conflicting information about it.

I copy here the email I sent to you:
you have to keep in mind that there are many cabal bootlegs around with different hardware layout.
The one in mame from red corp is a very similar copy to the original apart from the sound section (2x custom seibu + adcpm instead of 2x z80s + adpcm).
I can assure you that the sound is identical to the original. I haven't played it much but the shoots are definitely like the original, no errors.

if you had the recordings with wrong sounds, I can only think that there is some logic on the red corp bootleg which scramble the sounds, and other bootlegs manufacturers failed to reproduce...

yes, that is what I think. I'll track the z80, rom and msm5205 lines to see if there is some swaps

the first 4 data lines of the roms are correctly tied to the corresponding msm5205 data lines. the other data lines goes to some logic

Address lines between z80s and roms are not swapped

After dumping all the bootleg I confirm it's the same version as mame

There's a bitswap on the sound command from the main CPU.
