Final Fantasy VII - W-Item Trick

Equip W-Item Materia to any character in any weapon or armor slot. Go into battle and select W-item to open your item list. Move your cursor to the item you wish to duplicate and use it on your character. After this you need to chose a second item so go to any item you wish and select so the cursor hovers over your character but do NOT use it - instead press cancel and keep repeating the process of confirm, cancel, confirm, cancel. You will notice the item you originally used will start duplicating itself in your inventory. In the video above I wanted to duplicate Tranquilizers so I went to W-Item and selected Tranquilizer and used it on Cloud then selected my second item which happened to be a Hyper and pressed confirm but when the cursor hovered over Cloud I CANCELLED IT and repeated this process over and over.
