this is an old topic but I am currently playing through Shin Megami Tensei on the pc engine and most of the in-game music.. about 90% is I think PSG (ending, intro are redbook audio and a bunch of spoken dialogue tracks) but all the in-game track instruments and percussion sound very familiar falling somewhere in-between Magical Chase and Dungeon Explorer. It's hypnotic! The percussion certainly has a Magical Chase sound to them.
Just the intro of this...
Makes me think about this..
