Its the same P rom that Mame uses now for svcpcb I have that rom by the way Also sometime ago there was no code to decrypt the V roms so when it loaded the roms it also loaded the decrypted and encrypted V roms. Mame did the same thing. The code to decrypt the V roms is rather new. It was not known when Kawaks DEV was created. There is hope that someone will work out how to decrypt the M rom properly then there will be no need for the decrypted M rom. As you can see with the code below the encrypted and decrypted M roms are loaded, It was the same for the V roms not all that long ago. ROM_START( svcpcb ) /* Encrypted Set, JAMMA PCB */
