Master Command and Support Materia glitch

The Master Command/Support Materia Glitch is a glitch specific to Final Fantasy VII and involve pairing any command materia that can't normally be paired with Support materia, namely Double Cut and Slash-All materia. By equipping a Master Command materia with a Support materia, say Added Cut materia, and then having Double Cut or Slash-All equipped somewhere else on the character, whenever the player activates the command from one of the two said materia, whatever Support materia is linked to the Master Command will be used with those commands. In other words, by using this glitch, a player can attack 5 times using 4x Cut from the Double Cut materia, or attack using Slash-All and gain HP back via HP Absorb-Master Command.
