Okay, truth be told I've been away from Mugen for years now. I recently got back and acquired 1.0 version so everything is brand new to me again. Installed Warusaki3's Jotaro not too long ago and found that volume of his snd file is extremely low. I looked in the cns file and it's already at 255. Did I miss something?
