Finally I could dump the BRPOMs from the SIDAM Phozon PCB and I can confirm they match the existing ones.
The label and locations (suffix of ROM files) are:
PH1-1.1S
PH1-2.1R
PH1-3.1E
PH1-4.3E
PH1-5.5L
PH1-6.6R 
While the three PLDs -already dumped by Corrado- are (tough in my PCB two of them lack of label but Corrado properly reported them):
PH1-7.7B
PH1-8.4B
PH1-9.7R
So, the sound BPROM is the 'PH1-4.3E' while  @7R there is the PLD labelled 'PH1-9'@9R in my PCB there is an EPROM which I'm not able to read the type of but should be a 2764 for the SUB CPU code.
The only strange thing is that in MAME source there is also  a 'pallette.prm' BPROM which I can't see on my PCB, maybe some devs could explain this.
