My vote goes to Mansion of Hidden Souls on Sega Saturn and Sega CD.
It is more what you would expect to find on the pc than a console. I haven't played it in quite a few years, but if I remember corrrectly, it is relatable to Amber: Journeys Beyond and most (if not all) the characters are portrayed as butterflies. It isn't strictly a horror game, just has a few horror themes but enough that I would qualify it as a horror game.
