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

There's no map in this place so go up several screens until you find Ganon.

After a bit he will blow the torches out.

You have unlimited magic, so go wild with the Fire Rod! After a couple of hits he goes blue so stick him with an arrow. Then slash and stick. And so on. When he's dead, go back outside, through the teleporter, and go down to the centre area where Zelda and (if you talked to him) the Mole now are.

If you talked to the Mole, he dug up the greatest cache of all--1400 rupees! Go over to the cliff to talk to Zelda then just Turbo-key and enjoy the ending!

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."
