BS The Legend of Zelda/Quest 2/Dungeon 1

Head north. Kill all the snakes for a Key. Use it on the door and continue north. Grab the Compass. Head north and grab the Map. Kill the bats to open the door, then head west.

In this room kill the small gels and grab the Key. Head north and grab another Key. Watch out for Wall Masters in this room, they'll hurt you and dump you back at the entrance. Head west. Kill the stalfos (one holds a Key). Head north. Kill the boomerang bears (one of them drops some Bombs) and grab yet another Key. Head west and grab the Bombs (they'll vanish if you wait too long). Head north. Kill the Stalfos (one holds a Key) and return south (you can go north, but it's only the Old Man with a tip in Japanese). Head south five times until you reach a room with spikes. Push the left-hand corner of the diamond down and go down the stairs. Grab the Bow and return. Now either get killed by enemies or else work your way back to the entrance.

From the entrance head north, north, west, north, east, north, north, and fight Aquamentus. His weakness is that he moves very slowly, and his fireballs separate after shooting, making it easy to dodge between them. If you still have full health just shoot away at him with your sword, otherwise get in behind him and do your best to attack while dodging. When he's gone grab the Heart Container and head north. Grab the Triforce and you're done.
