Equipment bugs

The Equipment Bugs is a series of bugs found in various games in the series, most notably in the original Final Fantasy and in Final Fantasy IV Advance.

Final Fantasy
In at least some of the releases of Final Fantasy there is a useful cheat or glitch that can be used on the equip weapon screen. It has been seen on the Aniversery Edition but as of yet has not been confirmed in older releases.

Uses
Because of the function of this cheat, it has many uses beyond the obvious:
 * Equip units with weapons/armor they would not normally use.
 * Generate new weapons/armor from armor/weapons that you already have.
 * Duplicate weapons or armor from equipment already (or not) in your inventory (as a side benefit infinite gil early in the game).

How it is done

 * 1) First go to the configurations and turn Cursor to Memory.
 * 2) Go to Equip on Warrior. Select the slot you want to select the equipment FROM.
 * 3) Place another unit (doesn't matter who) next to warrior and select where the equipment will go TO.
 * 4) Return to Warrior. The cursor shoud be on the previously selected space.
 * 5) Press R/L and X at the same time in the direction of the receiving character.

In depth effects
Weapon to weapon:Enables weak units to wield Warrior's weapon set. This enables one to give Barbarian Sword to a White Mage. Armor to Armor:Enables weak units to equip heavy armor. Enables one to give Maxamillion to White Mage. Armor to wrong armor:Enables one to put stronger armor on the "wrong" body part. Same Maxamillion on White Mage's head. Weapon to armor:Enables one to spawn and equip an armor without actually having said armor in one's inventory. Give White Mage Knight's Armor from Warrior's standard Hammer. Armor to weapon:Enables one to spawn a weapon from an armor in one's invantory. Give Barbarian Sword to White mage spawned from Steel Gloves.

Misc.
Important things to note:
 * Equiping non-Shield armor as a Shield may result in the game freezing if it is used to guard. This results from the armor's lack of a sprite.
 * Easy Gil can be aquired by buying the "Hammer", and then spawning "Knight Armor"s at the beginning of the game.
 * Each Weapon has a coinciding Armor. One weapon will always spawn the same armor and in turn that armor will spawn that weapon.
 * Because there are more Armor pieces than weapons, some pieces spawn Unique Knives. In all cases, these are called "Knife", have unique stats and lack a sprite, perhaps making them claws.

Final Fantasy IV

 * Weapon bits do not have any effect (affects FF4A US and Jap 1.0 versions), which affects the following equipment


 * Asura's Rod (no Holy elemental)
 * Tiger Fangs (no Paralysis)
 * Dragon Claw (no Holy elemental, no dragon multiplier)
 * Loki's Lute (no multipliers applied)
 * Mist Whip (no Holy elemental, no paralysis)
 * Assassin Dagger (no Death)
 * Piggy's Stick (no Piggy)
 * Rising Sun (not a Wind elemental)
 * Requiem Harp (no drain effect)
 * Gigant Axe (no Poison)
 * Perseus Bow (not a Wind elemental)

The bug here is that all weapons beyond item #261 (0x105, Fiery Hammer) or effectively weapons starting from item #288 (0x120, Nirvana) are considered "armor". Weapons with elemental attack properties are considered elemental resistances. Weapons with elemental status attacks are considered status resistances. Weapons with racial multipliers are considered racial resistances.

This bug was fixed in the Euro and Jap 1.1 versions.
