PP underflow glitch (disambiguation): Difference between revisions

The [[PP Reset Glitch]] is a [[glitch]] in the [[bp:Generation I|Generation I]] Pokémon games. It allows certain Pokémon to have one of their moves' PP underflow to large values after reaching zero.

This glitch functions by abusing the auto-selection of moves caused by certain moves. The moves that cause this are the following:

* Bind

* Wrap

While these moves are not absolutely necessary for the glitch, it will make performing it considerably easier.

* A Pokémon to use for the glitch, preferably knowing any of the moves listed above. If the Pokémon used does not know any of these moves, it will have to be frozen and defrosted, which requires the opponent to either use a Fire-type move or Haze (Pokémon cannot thaw out on their own in Generation I.)

#Make sure the move that will be used for the glitch is at 1 PP, or a slightly higher number for the trapping moves.

#If the Pokémon used does not know any of the moves listed above, have it become frozen.

#Perform the move. If a frozen Pokémon is used, it will have to thaw out when the move is used for the glitch to occur.

The move's PP will now become 63, regardless of whether PP Ups had been used on the move.

The reason this glitch occurs is that in Generation I, there was no check to prevent a move's usage after an auto-select with 0 PP. This was first added in [[bp:Generation II|Generation II]].
