The Legend of Zelda: cheat codes & tricks
Verified NES name and controller codes, followed by useful tricks. Controller instructions refer to the original two-controller NES setup.
ZELDA name code

Register a new file with the name ZELDA to begin directly in the Second Quest. Its dungeons and item locations differ from the First Quest. Choose another name when you want the normal adventure.
Controller code: save without dying
Connect two NES controllers. Press Start on controller 1 to open the inventory, then press Up and A together on controller 2. Choose Save from the Continue/Save/Retry menu. This returns to file selection after saving your progress.
Continue after a Game Over
Choose Continue to retain your equipment and progress. You restart with three filled hearts at the overworld starting point, or at the dungeon entrance if defeated inside a dungeon. This is the ordinary continue option, not a cheat code.

Level 1 door trick

In the First Quest, enter Level 1, immediately leave, then re-enter. The locked northern door in the entrance room opens without spending a key. This is a small dungeon trick, not a button code or an unlimited-key unlock.
