The split-second previews at the end of the video feature clips from an early version of Zelda: Ocarina of Time, back when the game was still called Zelda 64. You can see many locales in this preview that didn't make it into the final game.
The game featured in the split-second previews at the end of the tape called Kirby's Air Ride was never released for the Nintendo 64. A revised version, however, did appear on the Gamecube.
