I don’t know if this is a waste of a good harmonica or a waste of a good NES cartridge but what you see before you is a harmonica hidden inside an honest-to-goodness NES game. The best part? They cost less than the $80 copy of Adventures of Link that the rental place around the corner from my house was selling back in 1988: $34.
Bring back those old memories of blowing into your faulty game cartridges with this Zelda II The Adventure of Link harmonica!
Imagine the look of surprise on your friends faces when they see you blow into this and realize it is not an ordinary game. Then you can really impress them when you begin to play the Legend of Zelda Overworld theme!
