Glitch: Difference between revisions

There are many different glitch types that are found to be the types of several glitch Pokémon and moves. The majority of them are used for very few Pokémon or moves.

There are several locations which can only be reached by way of a glitch or hack in the games. One of the most well known glitch locations is [[Glitch City]]. Other examples of this are areas in the [[Sevii Islands]] that are retrievable via their [[index number]] pointer, however, do not have any other data. [[Sevii Isles 8 and 9]] are the only index number areas which have actual map data. There are also other beta locations such as the [[beta Safari Zone]].

Placeholder items are often left in the game's code to prevent it from crashing if the data is accessed, such as the [[Teru-sama]] item in [[Generation II]]. Other generations likewise have placeholder items, with most appearing at the end of the item list, though a few, likely those removed during development, appear in the middle.

Often, placeholder items will be changed into real items ([[key items]] or otherwise) in later games of a generation. The [[GS Ball]], [[Clear Bell]], and {{key|II|Egg Ticket}}, which only appear in {{game|Crystal}}, are programmed into the games' [[List of items by index number (Generation II)|internal list]] where Teru-samas existed in {{game|Gold and Silver|s}}, and will, if they are hacked to be held by a Pokémon being traded to the earlier games, transform.

Thus far, glitch items that become real items from a later game only appear in [[Generation II]] and [[Generation IV]], as all items not present in {{game|Ruby and Sapphire|s}} that were reintroduced in {{game|FireRed and LeafGreen|s}} and newly-introduced in {{game|Emerald}} appear at the end of the list. They would cause a copy of Ruby or Sapphire to crash when it is selected, as they are beyond its item list. Generation II is the only generation in which all new items replace glitch items in the middle of the item list, thus not causing a permanent problem if transferred, as the {{DL|Legendary artifacts|Griseous Orb}} is the only item in Generation IV that is programmed at the same index number that a glitch item is present at in {{game|Diamond and Pearl|s}}, while the other items introduced in {{game|Platinum}} and reintroduced in {{game|HeartGold and SoulSilver|s}} are after the end of the Diamond and Pearl list, and thus crash the game if the glitch item in their place is selected in a game they do not exist in.
