This trick requires the W-Item materia. The materia is obtained after your party parachutes back into Midgar in Disc 3. After entering the subway tunnels in Sector 8, your party may walk away from the screen and encounter the Turks, or walk towards the screen to reach another subway section. Select the second choice and follow the subway tunnel until it ends at a dead end with the W-Item materia.

Equip the materia on the character with the item to be duplicated. When a battle begins, select the W-Item entry on the battle menu, select an unimportant item and use it on any character. On the second item choice, select the item to be duplicated by pressing Circle, then press X to cancel your selection and increase the number of that item in inventory. Repeatedly press Circle followed by X to accumulate 99 of the duplicated item. Note: This will only duplicate item selectable in battle and can not be used to duplicate the various sources, materia, weapons, or armor.

Refill HP

Cast Regen-All on your party, then quickly open the PlayStation lid when all opponents have been defeated. The game will be unable to load the victory screen, and may glitch while the HP for each party member fills. After everyone is at full health, close the lid to resume the game.

Easy Battle Square handicaps

During the "slot machine" handicap sequence, rapidly tap Square in the Battle Square section at Gold Saucer. The slots will slow down, allowing an easier selection of your handicap. Note: This trick will also work in a similar manner with Cait Sith's limit break.

Easy Chocobo races

While racing a Chocobo, hold R1 + R2 to slowly restore energy.

Cast magic three times at an opponent

Have all characters with Reflect status. Then, cast any attack spell on all three of your characters. The spell will bounce three times into the enemy, each with the attack power of a full spell.

Hints

Extra money

Sell a Master level All materia to get 1.4 million Gil. Since another All materia will appear when the original reaches master level, there will be no loss in usefulness.

Prevent back attacks

If a battle begins with a "Back Attack", press L1 + R1 to turn your character around before your opponents get a shot.

Nibelheim safe combination

The combination to the safe in the old mansion in Nibelheim that contains the key to enter the basement (and get Vincent) is Right 36, Left 10, Right 59, Right 97. Note: Push the button used to talk to people to select each number. After opening the safe and fighting the monster inside, a key to the other part of the mansion and Odin summon materia will be found.

Finding Vincent

Take the key from the safe that contained the Odin summoning materia in Nibelheim. After defeating the Boss, Lost Number, walk down into the basement. Open the door that was previously locked (right before enter the room with Sephiroth). Talk with Vincent, after finding him inside the purple coffin. When leaving the room, he will offer to join the party.
