Diamond Weapon glitch

Diamond Weapon Glitch is a glitch which makes Diamond Weapon-boss in the Final Fantasy VII to disappear from the World Map, altough it will ruin the players save file.

When the Diamond Weapon wakes and starts walking towards Midgar, the player has to stop it and fight against it. If the player enters the menu and saves their game exactly when the battle against Diamond Weapon is going to start, and then loads their game normally, the Diamond Weapon vanishes from the map. This altough makes it unable to finish the game, as Sister Ray is never launched, and the barrier over the Northern Cave still remains, making it impossible to fight against Sephiroth.
