I couldn't find this on the site, so I guess I'll start it. The Pokemon Colosseum infinite Master Ball glitch is a glitch in Pokemon Colosseum where you need a Master Ball and another Poke Ball (in this example, I'll use a Great Ball). After you get a Master Ball, use it during you first Pokemon's turn. On the second Pokemon's turn, switch the Master Ball's slot with the Great Ball's. When you use the Master Ball, the quantity of the Great Ball will decrease instead of the Master Ball's, thus, giving you infinite Master Balls as long as you have another Poke Ball in another slot. I'm not sure if it works in xD, though, because my xD barely works anymore, but I think it did.
