In the credits of Zelda II: The Adventure of Link, one of the names is not a name. It is a nickname: Tsukasan. A player who waited for the staff roll in 1987 would have had no way to know who that was. The man behind it was Akito Nakatsuka, and the music he wrote for that game is the same music that, years later, an orchestra would play for Super Smash Bros. Melee.
He began at Nintendo in 1984, when the Famicom was a year old and the company had only a few people whose job was sound. His name first appears on Devil World, where he shared the music with Koji Kondo. In the same stretch of years he is credited on three small games that Nintendo packaged in plain black boxes: Clu Clu Land, Excitebike and Ice Climber. Games that small leaned on their music to say anything at all.
Ice Climber came out on the Famicom on January 30, 1985. The music is short. It loops, and it was written for a sound chip that played only a handful of voices at once. One blogger who went through the score described it as barely three minutes in total. That was the music for two small climbers and a mountain.
On Zelda II, released on the Famicom Disk System on January 14, 1987, he wrote for a game that had changed shape. The first Zelda had been seen from above. This one scrolled sideways, and it had towns, palaces and fights in a way the first did not. The sound had to change with it. The palace theme from that game is the piece Nintendo later chose to carry forward into Melee. He is also credited, with Kenji Yamamoto and Yukio Kaneoka, on Mike Tyson's Punch-Out!! in the same year.
Then the shape of his credits changes. In the years that followed, Japanese sources list him far more often in a supporting role than as the main composer. He is credited as a co-composer on the Satellaview titles, including BS Zelda no Densetsu, alongside Yuichi Ozaki. He is credited as co-composer on Brain Age: Train Your Brain in Minutes a Day! alongside Minako Hamano. The Video Game Music Preservation Foundation also says he composed the Super Game Boy's music, and that he wrote the sound programs that other Nintendo composers used.
The list of what he did without his name at the front is long. He is credited with arranging Pilotwings 64, coordinating Super Mario Bros. Deluxe, supporting the sound on Super Mario Stadium Family Baseball, and supervising the sound on Wario Land: Shake It! and on Girls Mode. In those lines the verb is not composed. It is arranged, coordinated, supported, supervised.
Two younger composers, Soyo Oka and Shinobu Amayake, worked under him and used the sound driver he had written. The Video Game Music Preservation Foundation places this in his Super Famicom work. It was the sort of help a player never sees. The listener hears the song, not the program that plays it.
Sources do not agree on exactly when he stopped working at Nintendo, and no interview we found has him talking about what it was like to go from composing to supporting. We will not guess at his feelings. What the record does show is a man who, for about thirty years, put his hand to nearly every kind of sound Nintendo made, and who in the later part of his career is credited most often in the lines that describe helping. Whose work are you standing on without knowing that it holds you up?
