How did Virtua Fighter's music change on the Saturn?

Virtua Fighter (1993) has two soundtracks by design. Takayuki Nakamura composed the music for the Model 1 arcade original, the first fully 3D fighting game. When the game came home to the Saturn, Takenobu Mitsuyoshi took Nakamura's themes and arranged and diversified them for the new hardware, fuller and resynthed rather than simply ported.

The split became the series habit, arcade originals and arranged home versions issued as a pair, and it lasted. The soundtrack albums began in 1994, including an arranged disc performed by Sega's in house band B-univ, and nearly thirty years later the remastered vinyl release still presents the two scores side by side across two LPs, arcade on one, Saturn on the other, with liner notes and a new interview with series creator Yu Suzuki. The Library's Virtua Fighter shelf is built around the second game; this page documents the first game's music, where the two version tradition starts.
