Instructions
Make your way through the final level until the fortress starts collapsing. Follow Princess Zelda down two screens while killing all enemies in the way. Kill the dozen guards that appear on all sides of you.
Follow the Princess down another screen. Throw another Link over the pit on the right to break the pot. Climb down the ladder that appears.
Kill the enemies that appear and follow the Princess down the next screen. Enter the door and collect a Roc Feather. Go back out and climb a ladder up to the top.
Jump across to the door in the upper right corner. Stand on the switch under the pot so the Princess can cross over the ledge that appears; make sure she doesn't fall through. Enter the door and collect a Blue Bracelet.
Return to the door where you collected the Roc Feather. Exit the door on the right and hit the switch under the pillar to allow the Princess through the pillar. Go back in the door and come out the other side to fall down a ledge.
Jump right across two blocks and hit the switch. Run back and kill the enemies that appear. Follow the Princess down another screen.
Grab the Hero's Bow from the left side and kill the two enemies on the ledges. Talk to the Princess twice and kill the Iron Knuckle that appears. Follow the Princess until the floor collapses.
Line up your Links either vertically or horizontally and hit Ganon with your swords as much as possible. Avoid the beams of lights Ganon shoots from his trident; every time one hits you you'll have to kill a few more enemies to return to the fight. Watch for him to start throwing his trident in a boomerang arc and attack him heavily when he releases it until he collapses.
Watch the cut scenes, then stand in a horizontal line to guard the Princess. Keep her safe from the green ball Ganon is throwing. Knock the green ball back at Ganon five times with your sword.
Wait for the Princess to shoot her ball of light at Ganon. Charge up your Hero's Bow and shoot the ball of light as it comes between you and Ganon to end the level and the game.
