At the File Selection Screen, begin a new player and enter your name as ZELDA (all capitals).
Move the crane directly above the left conveyor belt using the B button. When the item that you want to pick up gets to the very top of the right conveyor belt (but not on the top conveyor belt), tap A. The crane will move down and grab the item.
In the color dungeon, there are tiles that when on them you bounce around and they turn from green to yellow to red and then a hole appears. If you walk over them with a pot in your hands, you will not bounce and will just walk across it, without changing the color of the tiles.
This only works on an item as expensive as the bow, or maybe the shovel if you're quick. Begin paying for the item and save and quit, (a+b+select+start) and then load your game again. You should have more money left (as much as remained when you saved) and you don't have to finish paying.
When you find a chicken in Mabe village, hit it with your sword around 15 times. After, chickens from Mabe Village will start attack you. BEWARE: You can lose all your hearts just from this. To get out of this, go into a different screen.
Beat the game without dying. You will see a picture of Marin in the ending.
Anytime you have the Hookshot equipped, if an enemy comes toward you, or it launches a projectile at you, simply use the Hookshot and as it launches out, the enemy/projectile will go straight through you, and you will take no damage.
You need the Boomerang, and the Rooster you get after Level 5. Throw your boomerang. Now pick up the Rooster. The boomerang will float underneath you, and kill anything you pass over while flying!
Normally you cannot enter dungeon 8 because of the fire thing you need the mirror shield to get around. But, if you have a potion, use the potion when you would normally die from the fire. You will be invincible for 3-4 seconds, in which you can run through the flames! After this, just defeat the dragon thingy and enter level 8!
Have both bombs and arrows ready, then press both buttons at the same time. If done correctly, the bomb should be flying on the arrow.
