Defeat Ganondorf the Easy Way
The final boss Ganondorf is by far the most challenging fight you'll encounter in "Twilight Princess." If you're having trouble defeating him, you can employ the following cheat. Instead of equipping a sword, pull out your fishing rod. After waving it around, Ganondorf will be inexplicably stunned. Use this opportunity to whack him until he wakes from his daze. Repeat and defeat.
Dungeon Saves
To increase the game's challenge, Nintendo prohibited saves while inside dungeons. This means you can't save immediately before boss fights. Using a simple glitch, however, you can work around this. While in a dungeon, use Oocoo, a bird-like character you'll find there, to teleport outside. Save the game. Even after you restart, you can now use Oocoo to teleport back to exactly where you were.
Easy Money
Ever look up and notice a flock of birds flying by? Nintendo didn't include them in "Twilight Princess" just for atmospheric effect. Using your boomerang, kill them off one by one. Once you've cleared the sky, 50 rupees will drop to ground.
Guidance
It is sometimes unclear what you're suppose do to advance the story in "Twilight Princess." If you're feeling stuck, go to the fortune teller by Agatha Castle and ask for your fortune. Although she seems to be babbling nonsense, this is actually Nintendo's way of helping you along--in a not-so-helpful manner. Try reading her fortune backward. You'll then know where to go next. Sometimes, she even tells you how to find an extra heart piece.
