The Legend of Zelda: Oracle of Ages is the time-themed counterpart to Oracle of Seasons. In it, the Oracle of Ages, Nayru, is possessed by Veran, Sorceress of Shadows. Link must travel throughout Labrynna's past and present to collect the 8 Essences of Time, power up the Harp of Ages, and defeat Veran.
SBD, however, exploits a save glitch, done by resetting the console while saving, in order to reach the credits in record time. Please read the author's comments for more details.
The encodes feature additional inputs as the game transitions to the credits.
