Slot 2: 100% Save in Hero Mode, name Link.
Slot 3: Save previous to the Zant fight, it's based off the Slot 1 save, which means it is almost a 100% save as well, but missing the Heart Container you get from Zant.
NOTE: Both Slot 1 and 2 saves include the bonus Wallet which you get from beating the Cave of Shadows all the way to the end (the 9999 wallet).
