I have from what i can is a Shinobi 16b with set 3 roms. Rom board #834-6499-03 that had a NEC z80 with a dead battery. This of course meant no sound. I swapped in a normal z80 and burned the decrypted file found at retro clinic, only to realize it was for set a different rom set. I now have background music, but no speech, i get a weird annoying BONG BONG BONG noise anytime there is supposed to be speech. Ive been searching around and haven't found any other decyrpted rom sets for shinobi. Am i using the right set, or is there another set and im just cant seem to find it?
