Nostalgia has hit me, and I have dusted off my old Super Nintendo which luckily still works, and popped in my Final Fantasy II cartridge which also still works! I remember as a kid, there was a way to split a weapon by doing something with it in your inventory during a battle, then running away. It allowed you to create an infinite number of copies, even for weapons that were "unique" in the world, such as the crystal sword, or Edge's Masamune.
This was a cheap way to get some gold by selling duplicate copies of powerful weapons. It was also very useful in providing Edge the Ninja with an unlimited supply of very powerful throwing weapons.
Does anyone remember this trick and how to do it on the SNES version of Final Fantasy II?
Keep in mind, this would have been technically Final Fantasy IV in Japan, but was released at the time as FFII in the U.S. as it was the 2nd U.S. release in the series.
