The second quest of The Legend of Zelda is what you get by having completed the game once. It is more difficult than the first quest. In this movie, the authors enter ZELDA as the player's name to start the 2nd quest without having to complete the game first.

The authors in this run also enter some of their own code, and don't really complete the game a second time either – yet somehow do. See the authors' notes for more details.

We also have a non-glitched run of this 2nd quest.
