To change the background music, start a new game as ZELDA,all Caps.

Go to the tree with the monkey in level 1.  When he throws them, hit

them with your sword.  Items like rupees,guardian acorns, a piece of

 power, and nothing in them will ever harm you in any way.           

To fly, you must have the Boomerang and the Rooster.  Throw the 

Boomerang and pick up the rooster.  Then the boomerang will hover

below you.  You cannot get attacked by normal enimies, but you 

 can attack them!!!                                               

To build a missle, place the arrows in one hand and bombs in the

 other.  To fire, press A+B stimultaneously.                     

Play the crane game and grab the two rupees by placin the crane's

shadow on the upper left hand of the conveyer belt.  Wait until the

 item you want is about halfway between the upper and lower right hand

corners.  You can go back and repeat the process.  It's a lot better

 than stealing.                                                    

Well all of the rest of the codes are basically the same!
