Line 1: {{Arbitrary code execution}} ~~{{Major glitches}}~~ {{Summary page}} {{PRAMA\|glitch-pokedex-ace}} '''Glitch Pokédex sortings''' are invalid Pokédex listing sortings found in {{GSC}}. ~~Like~~The ~~valid~~2nd ~~sortings~~generation ~~including~~of pokémon games allow the player to select three different modes to order pokémon within the pokédex. These modes include "New Pokédex mode", "Old Pokédex mode" and "A to Z mode",. ~~there~~When ~~are~~a ~~glitch~~specific ~~Pokédex~~mode ~~sortings~~is ~~which~~selected, ~~affect~~the orgame ~~are~~will ~~interpreted~~save bythe value of the ~~game~~last inselected ~~unintended~~mode in ~~ways~~memory. ~~Like~~When ~~with~~the ~~many~~pokédex ~~[[:category:glitch~~is ~~things\|glitch~~selected ~~things]]~~from the start menu, ~~glitch~~the game uses a jumptable to select which sorting function should be used. By changing the value of the last selected mode, it's possible to index this jumptable out of bounds. Because of this, certain modes ~~Pokédex~~are ~~sortings~~able ~~can~~to [[arbitrary code execution\|execute arbitrary code]], such as glitch mode 09's execution of $FA20 (Echo RAM for $DA20) in Crystal. ==Technical details== When opening the pokédex, the game will retrieve the last selected dex mode from wLastDexMode and use that to retrieve a pointer from Pokedex_OrderMonsByMode.Jumptable. {\| class="wikitable" !

With glitches, the [[duplicate key items glitch]] can be used to set up the expanded Balls pocket, where the glitch Pokédex ~~sortingcan~~sorting can be modified from the balls beyond ball 12. Another way of accessing arbitrary code in {{GSC}} is through the [[Coin Case glitch]] (in English Gold/Silver only) or [[Glitch item#TMs and HMs outside of the correct pocket\|TMs and HMs outside of the correct pocket]]. The glitch TM/HM method is ideal because TMs and HMs can be forced into the PC items; also available through the expanded Balls pocket. In Gold and Silver, modifying address C6D8 on the option screen (list of available Pokédex modes) will allow the player to access glitch sortings in a different way to the above method.
