Final Fantasy III Hints & Cheats

Hold Up-Left + Select + Start and Power On the console. At the black screen, release the Select button to see the hidden message.

After you defeat the Death Wizard, return to Argas Castle. Switch your white mage to the front of your party and open the locked doors. In one of the doors is another white mage. Talk to him to get elixirs.

After you beat the giant turtle, change your party's jobs and enter the cave again after leaving to get more treasure. Inside is your first spell and several good weapons. There are a few spots in the cave that obviously look like dead ends, but are actually fake walls filled with treasure chests.

Requirements: Sight and a white magic user

Give Sight to a character that can use it along with the spells you want to duplicate. In the Magic menu remove the spells that you want duplicated and use Sight without leaving that menu. Now you should still have the spells in the Magic menu and a copy in the Item menu. For unlimited Gil copy and sell expensive spells.

Have 4 dragoons or less as your party and have one of them get poisoned. Then have everyone jump. This should make them all stay in the air, out of harm's way, but still taking damage from the poison.

In Canaan, after saving Cid's grandma/wife, Cid will jump out of the way revealing a secret storage room. If you keep talking to him after the first jump, he will continue to jump each time you talk to him. Eventually he will jump out of him house into the darkness of the night. Like a ninja.
