Infinite ball glitch

The Colosseum Master Ball glitch is a glitch in Pokémon Colosseum that enables the player to re-use the Master Ball, or any other type of Poké Ball, as many times as he wants. Essentially what this means is that the player needs only to buy one of each kind of Poké Ball during the game.

The glitch is performed by selecting a Poké Ball with the player's first Pokémon's turn and, with the second Pokémon's turn, switching the type of Poké Ball chosen with another Poké Ball in the bag (using the Y button). After the Ball is thrown, the Poké Ball pocket will still have the same amount of Poké Balls, as if the Ball just thrown had not been used.

This glitch does not work on Pokémon XD: Gale of Darkness.
