two Nintendo-franchise-based pinball machines, pinball designer Jon Norris was tasked with designing the table. Before it was completed, Gottlieb decided to repurpose the game with an American Gladiators theme. Licensing for this version ultimately fell through and the game was released as simply Gladiators (November 1993). In 1998, Nintendo cancelled Ura Zelda, the Ocarina of Time expansion disk for the 64DD due to poor sales figures for the 64DD peripheral. In 2002, Nintendo released a GameCube bonus disc called The Legend of Zelda: Ocarina of Time Master Quest. It contains emulated versions of Ocarina of Time and Ocarina of Time Master Quest, which Aonuma and Miyamoto each confirmed is Ura Zelda. In 2001, under license from Nintendo, Capcom cancelled the release of The Legend of Zelda: Mystical Seed of Courage for Game Boy Color. Working with a Capcom team, Yoshiki Okamoto was originally tasked with designing a series of three Zelda games for the Game Boy Color. Referred to as the "Triforce Series", the games were known as The Legend of Zelda: The Mysterious Acorn: Chapter of Power, Chapter of Wisdom, and Chapter of Courage in Japan and The Legend of Zelda: Mystical Seed of Power, Mystical Seed of Wisdom, and Mystical Seed of Courage in the US. The games were to interact using a password system, but the limitations of this system and the difficulty of coordinating three games proved too complicated, so the team scaled back to two games at Miyamoto's suggestion. The Legend of Zelda: Oracle of Seasons was adapted from Mystical Seed of Power, The Legend of Zelda: Oracle of Ages was adapted from Mystical Seed of Wisdom, and Mystical Seed of Courage was cancelled. Before its 2006 release, both Link and Samus from the Metroid series were planned to be playable characters for the Wii version of Marvel: Ultimate Alliance, but they didn't make the final release because they weren't Marvel characters. In 2011, an unnamed Zelda 25th Anniversary Compilation was cancelled. To celebrate the 25th anniversary of the series, Nintendo of America originally had planned to release a compilation of games together for the Wii, similar to the collector's edition disc released for the GameCube in 2003. Nintendo of Japan's president Satoru Iwata and Shigeru Miyamoto decided against releasing it, believing it would be too similar to the Super Mario 25th Anniversary collection released in 2010. Retro Studios had two Zelda games in development.
