Of course, this shot doesn't really prove anything -- that header at the top could just as easily read "ULTRA Punch Out!!" or "The MORE Fantastic Adventures of Dizzy" and work just as well. We're sure some photoshoppers out there will have their own ideas of what other big name sequels this photo could possibly confirm. What we're really interested in, though, is what this purported music actually sounds like. Anyone out there with some MIDI sequencer skillz want to help us out?
[Update: The community comes through! Check out the alleged theme as either a MIDI (thanks Dan H.) or a violin synth MP3 (via Giant Bomb)]
[Update 2: Check out this awesome remixed version of the "theme" (via NerdiestKids)]
