I know this wasn’t at all the point of your post but there N64 Zelda games have pro logic surround as well. They just don’t have the pro logic logo. Which is why I’m even making this post because a lot of people don’t even know. You just put it in surround mode and even though it doesn’t say anything about pro logic it absolutely works wonderfully. Not just ambience, things happening behind the camera come out the rear speakers only. Test it by throwing a bomb behind the camera. OOT doesn’t say anything other than ‘surround’ mode, MM does actually say ‘dolby surround’ on it. But not very many N64 games had this so just thought I’d throw this information out there to anybody that likes the N64 Zelda games and has never tried the surround mode, it sounds actually very good.
