Line 1: {{disambig}} ~~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.~~ '''PP underflow glitch''' may refer to any of the following glitches in [[bp:Generation I\|Generation I]] that allow the player to get 63 PP on a move with three PP Ups applied. ~~'''Moves that cause an auto-select'''~~ ~~This glitch functions by abusing the auto-selection of moves caused by certain moves. The moves that cause this are the following:~~ * Bind * Clamp * Fire Spin * Hyper Beam * Metronome * Mimic * Wrap ~~While these moves are not absolutely necessary for the glitch, it will make performing it considerably easier.~~ ~~'''Requirements'''~~ * 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.) ~~'''Procedure'''~~ ~~#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.~~ ~~'''How it works'''~~ ~~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]].~~ [[Hyper Beam automatic selection glitch]] The amount of PP given to the move after it underflows is determined by the amount of PP Ups that were used on the move. In Generation I, the PP of moves was stored in one byte, in which the first two bits stored the amount of PP Ups used on any move, and the last six stored the amount of remaining PP. So, when a move with 0 PP is used, its value resets to 255, giving the move 63 PP. This value is higher than any attainable without this glitch, as moves in Generations I and II with 40 base PP maxed out at 61, likely due to a lack of data space. If no PP Ups were previously used on the move, the maximum amount will be applied. If PP Ups were previously used on the move, the move will lose one PP Up.
