      Good day everyone.

       

      I’d like to request a very important feature that I think will resonate with the videogame preservation oriented folks in here.

       

      Dolby Prologic support, you know, that ancient surround solution from back in the day that encoded multichannel information into a stereo track to be decoded by a fancy AV System.

       

      SNES, PlayStation, N64, Gamecube, PlayStation 2, Wii and many more consoles took advantage of it even though sometimes it wasn’t even advertised.

      TV shows and a LOT of VHS tapes, Laserdiscs and DVDs also have tracks encoded in this format.

       

      The trouble is, more and more AV Systems are dropping Prologic decoding support altogether and because of space constraints people are moving to Soundbars and those will certainly not pay an extra fee for 20th century tech so most of them have their own upmixing algorithms that mess up the Prologic soundstage.

       

      I noticed that the OSSC Pro has a quad stereo mode that, in theory, could easily be modded to support old school Prologic and it would be a game changer for gamers and physical media collectors out there, I mean, come on, we are sitting on real, developer intended surround sound out of SNES and PlayStation 2.

       

      Pretty please?
