Though Star Wars NES tends to get a little iffy with some of its original music, no retro game that adapted A New Hope fails to impress musically. For Namco's Star Wars, Kawada worked with a senior sound designer whom he does not name but describes as "a pioneer in the field of game music, with extensive experience in and knowledge of orchestration. We took key sections of the score and adapted them so the parts that remain sound like an arrangement of the score. Even now when I see [him], we talk about how difficult that was back then."
Still can't be as difficult as the game itself, though.
