The Dreamcast version was fairly close to the PC version, the N64 I think had a lot of graphical sacrifices if I recall.I never had that on the Dreamcast, but I can't rule out it having been ported there. I certainly saw it on the N64, although it's not a game I've personally ever owned, so I've not given it a try under emulation so far.
Likely just needs to be compiled, pandora already has it: http://repo.openpandora.org/?page=detail&app=moonlight_ptitseb.“Moonlight for PS Vita (Homebrew)
Stream to a Homebrew-enabled PlayStation Vita (Community port)”
Would that be an option for us or?
