While waiting for Skyward Sword to come out I have sucessfully completed 100%:

• The Legend of Zelda: Twilight Princess
• The Legend of Zelda: Majora's Mask
• The Legend of Zelda: Oracle of Ages (not 100%, because of the password nonsense, but I plan on completing Oracle of Seasons 100% when it gets in the mail with my Seceret to Holodrum password)
• The Legend of Zelda: A Link to the Past
• The Legend of Zelda: Ocarina of Time 3DS
  

Now I'm working on:

• The Legend of Zelda: Oracle of Seasons
