So if I wanted 99 Ultima Weapons, I would put in this code:

02099F90 00630471

One short code gives you 99 powerful weapons.

Note: Make sure you have an item in your first slot that you don't want, or put the item in first slot that you want 99 of. Make sure you do this before entering in the codes, if not then you will lose that item forever if you save.
