Sound test:  Successfully complete both games to unlock the sound test option.

Final Fantasy 1: Bonus puzzle game:  Enter the ship, hold A and press B(55). Arrange the tiles in order from 1 to 15 to collect 100 Gold.

Final Fantasy 1: Defeating Chaos:  Chaos, the last Boss, is very difficult to defeat. Use the Blood Swords that were obtained at Pavel's house, etc. and he will die in two hits.

Final Fantasy 1: Blood Swords:  To get the second most powerful Blood Sword, go to Pavel's house after you are halfway through the game. He will give you all of his treasures.

Final Fantasy 1: Dead Link:  Go to the town of Elfheim. There is a group of three gravestones near the White Magic shop. If you search the one on the left, it reads "Here Lies Link".

Final Fantasy 2: Concentration card mini-game:  After getting the snowcraft, use it north of Salamand. During the game in the snow area, hold A and press B(22).

Final Fantasy 2: Recommended party:  To get an very good party, train Firion in Swords, Guy in Axes/Black Magic, Maria in Spears/White Magic, and Leon in Swords. On the Soul Of Rebirth, train Minwu (Mindu) in Staves/White Magic, Scott (Gordon) in Swords/ Black Magic, Josef in Fist, and Richard (Gerath) in Swords.

Final Fantasy 2: Mastering:  To master any weapon or magic, use it every turn of every battle and equip two of the weapons (for example, two swords, two shields, two axes, etc.). You will get to level 16 easily.

Cheaper inn prices:  Use Cure on your entire party until your life is full. The inn will then just charge you for MP healing.

Evil Eye:  Magic spells are expensive. However, there is one particular monster that is capable of making it easy for your economy, and helps to level up very quickly. In the Cavern of Ice, directly in front of the chest which contains the Levistone treasure, you can find the Evil Eye (HP 162, Gil 3,225, experience 3225, weakness: none). You should be able to defeat it with a couple of good hits. Every time you defeat it, just walk away a step and return to the spot where it appears to fight it again. Repeat this for easy money and experience. It is rather easy to complete this short dungeon, and the Evil Eye willnot give you much trouble. No investments (such as Ether) are required.

Earthgift Shrine:  This dungeon is easy to complete. However, the Bosses found at the end of it might not be so easy to defeat if you are not prepared. Every time you defeat a boss, you will be kicked out of the dungeon and must complete it again in order to fight the other Bosses Also, once you defeat them, they will be there again the next time. They all like to use Quake; it is a good idea to be protected against it (Ribbon, Nulldeath).

Echidna (lower right): HP 4,800, X-potion (fully restores HP), weakness: none.

Cerberus (lower left): HP 4,000; Kotetsu (small katana usuable by Warrior/Knight-Red Mage/Red Wizard-Thief/Ninja), weakness: none.

Ahriman (upper right): HP 5,000, Dry Ether (fully restores MP), weakness: none.

Two-Headed Dragon (upper left): HP 4,500, Bard's Tunic (a light loose-fitting tunic usable by anyone), weakness: none.

Whisperwind Cove:  Once you enter this dungeon, you will have to travel across an insane parallel universe filled with bizarre events and new powerful creatures. This crazed-out dungeon consists of 40 floors where you will encounter mini side quests such as the Fairy Town of Feyhem, the dwarf trading adventure "Monsters Have Feelings Too", save a little town from the phantom train, a giant beaver game, the fallen kingdom, and mage town. Every ten floors or so, you will encounter a Final Fantasy 6 Boss in some of the most difficult battles in the game. The following are their identies, weaknesses, and item given. Do not expect any gil or experience from any of them.
Typhon (Mr. Chupon): HP 10,000, Genji Helm (heavy helm usable by Warrior/Knight - Thief/Ninja), weakness: ice.

Orthros (Ultros): HP 17,000, Rune Staff (casts Healara, usable by White Wizard), weakness: fire and lightning.

Phantom Train: HP 9,999, Megalixir (fully restores party's HP and MP), weakness: fire and dia.

Death Gaze: HP 30,000, Lightbringer (sword that casts Holy, usuable by Red Wizard), weakness: fire and dia.

Because of all the trouble that this dungeon represents, once you complete it, the mighty Ultima Weapon (sword bound to its wielder's HP usuable by all the higher classes) is awarded to you. Additionally, several nice pieces of equipment will be found. It is recommended that you to attempt this dungeon with your characters at level 60, at least. You should also have 99 Ether and Turbo Ether and all the maximum level spells. Throughout the whole thing, there are only a few chances to go back to the surface and very little places to heal. You will need lots of magic and items.
