Legend of Zelda Cheats (Nes)

Enter level 1 in the first quest. You should see a locked door. Immediately exit the
dungeon, then reenter it. The locked door should now be open.

In the second quest, the dungeon maps aren''t always accurate.  First of all, you might be
able to enter a place on the map where no rooms are shown.

  Also, some ares in the dungeons can only be accessed by walking through the wall.  If
there is one room in a dungeon in which you haven''t been, and you can''t open a portal
with a bomb, try walking through a wall by pressing against it.  If it works, you''ll
hear the secret music and you''ll pass right through it.

If you want to play the second level of Zelda, call your player 'Zelda'.
