Isn't it already supported? Well at least with Dolby Pro Logic. It's not like the newer surround sound, but it's still something.

the nintendo 64 DOES NOT support any advanced form of surround sound. It is pseudo stereo surround.

If you want to have surround sound you are going to need to use a sound card or a receiver that supports Dolby Pro Logic. You are also going to need a game that supports surround sound. This is the best list of those games I could find:

Banjo-Tooie
Conker's Bad Fur Day
Donkey Kong 64
FIFA 98: Road to World Cup
Hercules: The Legendary Journeys
Indiana Jones and the Infernal Machine
International Superstar Soccer '98
International Superstar Soccer 2000
Jet Force Gemini
Ken Griffey Jr.'s Slugfest
The Legend of Zelda: Majora's Mask
The Legend of Zelda: Ocarina of Time
Mickey's Speedway USA
Perfect Dark
Pokémon Stadium 2
Resident Evil 2
South Park: Chef's Luv Shack
World Cup 98

Note: This only shows N64 games that have Dolby Surround, some games might have surround sound but didn't pay for the Dolby license.

hey squall would it be possible to code some something like you guys did for vba-m that inulates surround sound?

several of those games don't have Dolby Surround at all and as i said, its a Stereo Pseudo surround. a DPL mixer will also not work as it not a Pro Logic signal.

Pro logic will only output 5.1 if the source is encoded in the PL format. so when set to PL it will only output as stereo.

Prologic 2 is the same as PL1, in that it will only provide proper 5.1 mixing when the audio signal is encoded to DPLII. However it will simulate a 5.1 environment by using advanced mixing. However since as i said, the N64 is only capable of Pseudo surround, It is only a upmixed stereo feed and will not have any positional or environmental audio effects.

Most 5.1 sound card drivers already provide a manner to upmix a stereo signal to 5.1,

Creatives drivers call it CMSS2, (older creative cards like the SBLive don't support CMSS2, but mix the front speakers with the rear with some distortion by default.

not sure about realtek's or AD's drivers.

First, Dolby Surround will work on a DPL mixer. Second, when you say "stereo pseudo surround" you make it sound like it's a stereo signal, with no surround information, being converted into 5.1. Where in reality it will give you a single surround channel because the channel is matrix-encoded into the audio. While it is not 5.1 surround sound, it still has some basic surround information (which is left, center, right, and mono surround).



From Dolby's website:
Dolby® Surround is the consumer version of the original Dolby multichannel analog film sound format (Dolby analog and Dolby SR [Spectral Recording]). When a Dolby Surround soundtrack is produced, four channels of audio information—Left, Center, Right, and Mono surround—are matrix-encoded onto two audio tracks. These two tracks are then carried on stereo program sources such as videotapes and TV broadcasts into the home, where they can be decoded by Dolby Pro Logic® to recreate the original four-channel surround sound experience.

no it won't. DPL mixing only supports DPL, the device must support mixing for dolby surround, otherwise its just stereo.

As it is, sound cards can immitate this now anyway,
