The following secret can be classed as cheating!

Ever wanted to know how to get 99 of all usable items in battle? Then here is a quick guide in how you can get hold of this "glitch" in the game.

REQUIREMENTS

For the Unlimited Items glitch, all you need is the W-Item command materia which you can get from the Midgar Train Tracks in disc 2.

LET'S GET RICH!

Once you have got hold of the W-Item command materia you will now need to equip it to any character who is in your party. Doesn't matter about which growth rate you get since I find that W-Item is only useful for this.

Now you need to get into a battle, it is advised to be fighting easy monsters since your not going to be able to issue commands unless you want to take forever to increase your items. Once in battle wait for the character with W-Item equipped and select W-Item for the command list. Select any old item that you are not going to increase through this session, then when you can select the second item choose the one that you wish to duplicate. Instead of double selecting, select the item then press cancel, keep on doing this and you should see the item increase by one each time.

You can do multiple items per battle, but you can only duplicate one item at a time.
