The Navi Trackers mode in The Legend of Zelda: Four Swords Adventures started life as a remake of Marvelous: Mouhitotsu no Takarajima, a Japan-only RPG for the Super Famicom. In a 2004 interview with Nintendo Online Magazine, director Yoshinori Tsuchiyama stated that its rebranding as a Zelda game was the result of "the desire to make a complete departure from Hyrulean Adventure, and to incorporate a sense of realism produced by having the game talk to the players through the screen." Tsuchiyama, co-director Toshiaki Suzuki, and series producer Eiji Aonuma previously worked on Marvelous: Mouhitotsu no Takarajima. Because of these circumstances, The Legend of Zelda: Four Swords Adventures contains unused assets for the Marvelous remake in its code, including icons, backgrounds, cursors, and a 3D model for Gina (whose role is filled by Tetra in the final game).
