PGM 2 and speaker problem

[slai50]

Anyone here encounter a problem with PGM2 games( Oriental Legends 2 and KOV 3) sound and music coming out of only 1 speaker? I have a supergun and PC speakers connected to a BVM. It's not the speakers because consoles and other PCBs has music and sound coming out of both speakers when connected. Any ideas?

Is it cos your using the Mono output on the jamma finger?? Or do other mono Jamma games work fine??

How can I tell if I am using the mono output on the jamma finger? Only other PCB I have is the STV multicart and the sound is coming out of both speakers.
