BS The Legend of Zelda: Inishie no Sekiban/Week 4/The Final Battle

This game, like Majora's Mask, actually has two endings.

The Good Ending
You solemnly put the Master Sword in its pedestal to rest once more, and... you vanish! You have gone back into your own world from whence you came. You saved all of Hyrule, and they did not even know your name. Sasharhala Zelda takes one last look back, and then she too departs.

The Bad Ending
Simply run out of time in Week 4 and you see your fainted body outside the witch's hut. The message says something like "What happened? You ran out of time! I guess you gave it your best shot."
