The Punisher! (Sounds is too low)

I can't find the usual sound adjustment option for this game that is existent in other CPS2 games. Need help here.

That's because the game is CPS1, not CPS2 :p
Which emulator do you use?

MAME32 Plus.

List of Mame keys.

Volume control is usually the tilde key (directly above the TAB key).

Does not work. I just turn up the speakers then.
