Many people saw Final Fantasy III as the first Final Fantasy to ever be created. The name says which installment it really is, but it was the first game to create a proper fan community. Square-Enix and Nintendo know the perfect way to resurrect a title released in 1990 and change it to suit the modern standards. A once “greatest game ever created for the Nintendo console”, FF III is now packed with Wi-Fi support and decent graphics, considering that the DS is a portable console. FF III features a group of kids set on a quest with the purpose of bringing balance back into their world. That's the moment where the trademark Square-Enix crystals join us once more giving the youngsters a part of their power. It was Final Fantasy VII that started the remake-mania, and now we have FF VII for the PS 3, FF VI for Nintendo Advance and finally Final Fantasy III for the DS. A couple of cheats will hurt nobody and feel free to use those tips and tricks:

Glitches

Dive into Saronia?
YOU MUST HAVE THE NAUTILUS FIRST. SAVE BEFORE DOING THIS.

If you take the nautilus and head to the western side of Saronia (the continent with the castle on it, upper left corner of map, not on the floating continent), there's an area with the most trees on that side. There should be a place between two rivers. If you touch down on the tip of this area that touches the ocean, you can actually dive into it. From there, you can 'bore' into the continent. If you exit into the ocean, it will push you out and you have to dive into the continent again. When tunneling through the continent, you won't encounter any creatures, as far as I can tell.

It is possible to surface at any point within the continent. In fact, you can surface through mountains. Like diving into the continent, entering an area you can normally fly around in will shove you out of the other area and not let you back. With enough skill and dumb luck, you can actually get to Falgabard without the Invincible. Of course, you can't leave after that, but hey, it's still funny.

Item Duplication
In Final Fantasy III, all useable items (not weapons/armors/magic) can be duped using this method, as mentioned, please use at your own risk.

Procedures:
1)Open menu screen via non-battle.

2)Select "Items"

3)Put the item you want to duplicate in the very top left corner in your item list

4)Enter a battle randomly

5)When in battle, go select "Item" on any characters.

6)Your cursor should be at the very top left of the item box, the item you have placed there. Once you're here, hit UP and A button at the same time

7)This will briefly take you to Weapon/Shield list (about 1/2 second). If you see this, the code has worked after you hit "cancel' or B button. Go to your inventory and you will notice that the item quantity has been added by one.

With this method, you are able to duplicate any demishable items, even items you can't by such as Chocobo's Rage, Elixir, Phoenix Down.

Secrets

How to obtain access to secret dungeon
In the Nintendo DS version of FF III, there is a secret dungeon that contains a secret boss harder than the last boss, in order to obtain access:

1)Send a total 7 mails to another PC (one or multiple) using Mog Net.

2)Send 4 mails using Mog Net to the NPC: The 4 Elderly

3)Send 4 mails to King Arusu and after reading the fourth one, you'll unlock a quest

4)Go ride on the airship that can go underwater

5)Head for the floating island and once finding it, go exactly east..

6)You will eventually see a shadow in the waters, once you do go underwater to enter the cave

7)Soon after entering the dungeon, you will meet the secret boss

*This boss is notorious and mean. It does a total of 4 attacks per sound and also uses Meteo. Please be at a very high level before attempting this fight.

How to obtain secret job: Onion Swordsman
Back in the original Famicom FFIII, Onion Swordsman was the first job you start as (unlike Freelance from the DS version), but you can play this job in the Nintendo DS version as well by unlocking it. Onion Swordsman is one of the most powerful jobs with the Onion Equipment + past level 90's.

How to obtain:
1)Register someone else's (or multiple) communication ID under Mog Net.

2)Send message to another PC 7 times

3)Send and receive 4 messages from Topapa, on the fourth one you will receive a message to do a mini-quest.

4)Go to Uoul (First town in the game)

5)Talk to Topapa

6)Go to the cave up north of the cave

7)At the drop hole, you will have an event and then will be proceeded to fight 3 bombs

8)After the battle, you will obtain a piece of crystal, which will unlock Onion Swordsman
