PSG tips


As SCC is combined is PSG in some demos and Konami games, it gives a stereo effect, that you can enhance by a fine tuning in the mixer

Hear only PSG

- de-select the other soundchips in the mixer

- if you hear nothing, then take a look below

Hear PSG in stead of other soundchips

- de-activate the MSX-MUSIC emulation and/or the MSX-AUDIO emulation in the Options/Sound menu

- use the MSX2 Only PSG machine, especially if you want to run a game with automatic choice between PSG and MSX-MUSIC, but want to hear the PSG sounds in stead of MSX-MUSIC.

You can view on this page the list of the rom games with automatic choice between PSG and MSX-MUSIC.
