Line 1:
'''Partially unused''' or '''semi-glitch things''' are a side effect of how data in the Pokémon games is retrieved. Functions that retrieve data may simultaneously load valid but unused data leftover from development, as well as [[glitch]] data which was never intended to be added there.
==Examples==
Line 14:
===Items===
{{Main|Unused items}}
*[[
*The item versions of the BoulderBadge through to EarthBadge have valid names and effects, but do not appear as actual items and may be considered as glitch items. However, they appear in a different form for the list of badges at the badge man's house in Cerulean City; where instead selecting them brings up a description for that badge. The BoulderBadge and CascadeBadge act like throwing bait and throwing a rock in the Safari Zone respectively (affecting the opposing Pokémon's catch rate), while the rest bring up Oak's message that it isn't the time to use the item.
*The unused PP Up copy may also be considered as a glitch item, and brings up Oak's message that it isn't the time to use it. It also has a different price at the Poké Mart (worth 9800 Pokédollars instead of 0).
Line 21:
*The unused inventory version of a Game Corner Coin. In the source code leaks, it was called the パチンコダマ (Pachinko Ball).
*The set of unused rank names and badges, such as かいがらバッヂ (ShellBadge) or プチマスタ (Petit Master) are a [https://tcrf.net/Development:Pok%C3%A9mon_Red_and_Blue/Miscellaneous_Data#Badges_and_Ranks leftover from development] (their names are corrupted/[[mojibake]] outside of the Japanese versions), but unintentionally can be forced as glitch items beyond the index number of the last valid non-TM/HM (Max Elixer; 0x53) with invalid effects because the data structures for the names are close together (this also applies to the names of floor destinations beginning with [[B2F]], strings from the new name screen such as [[ItemDex/RB:176|JACK]], etc.)
*The [[Teru-Sama]] (カビチュウ) are remnants of unused items but may also be considered as glitch items. There are 32 different Teru-Sama in Gold/Silver, and four of them became Pokémon Crystal exclusive items; Clear Bell (hex:46), the GS Ball (hex:73), the Blue Card (hex:74) and the Egg Ticket (hex:81). Its international name may be a reference to Western-release programmer [[bp:Teruki Murakawa|Teruki Murakawa]] and the Japanese honorific [[
*There are duplicates of [[TM04 (useless)|TM04]] and [[TM28 (useless)|TM28]] in Generation II without any uses, only to give, toss or sell them for 19660 Pokédollars. The item descriptions match the real TMs. Their index numbers are located just after the real TM04 and TM28 items.
*TM51-TM55 from Generation I (which have the effects of HMs Cut through to Flash as disposable TMs) have their names as a result of a subroutine to generate TM and HM names based on the index number. HM08-HM13 also exist in Generation II.
Line 29:
*[[Juggler (unused Trainer class)]]'s name was originally ジャック (Jack) during a period of development when he was a Trainer known as Shinjuku Jack (a reference to Takayuki Haneda, pseudonym "Shinjuku Jacky"; who mained Jacky Byran in the game [[wikipedia:Virtua Fighter|Virtua Fighter]] by [[wikipedia:Sega|Sega]]) before all references to Jack were removed (except as a pre-set name) and the Trainer in his place became the unused Juggler copy. However, a list of Trainer Classes in Japanese mentioning Jack where the unused Juggler would have been remains in the final versions of Pokémon Gold and Silver Versions.
*A similar situation to the Juggler also applies to the [[Chief (unused Trainer class)|Chief]]. Furthermore, some extra unused information can be retrieved from his Japanese name Silph's Chief or Silph's Manager (シルフのチーフ), possibly suggesting he was linked to the Silph Co. before being cut from the game. In the source code leak, the Chief also used Blaine's newer design (like in the final games) instead of the Scientist sprite although this did not survive by the time the final ROMs were released. (At the time, the actual Blaine [https://tcrf.net/File:PokemonRGBY-BlaineOriginal.png had his own cut design], which can still be seen in the manuals of the final game)
*[[Prof. Oak (unused Trainer class)|Prof. Oak]] is another unused Trainer class in Generation I. He has three rosters (and they only differ based on the final form of the starters; Venusaur, Charizard or Blastoise) at levels even higher than the Pokémon League Champion, which has lead to speculation that he was the original champion, or served a similar late game (or even post game) role. Professor Oak however is sometimes discussed together with Pokémon glitches, because he can be accessed with the name character {{MN}} in the [[old man glitch]] (as the third, fifth, seventh, ninth and eleventh character in the player's name) or Special stat 226 [[Trainer escape glitch]]. Often he is fought with the wrong roster rather than with one of his three valid ones.
**When battling any Trainer using a glitch, the player must specify the roster if they want to fight a specific team, and the later the Trainer class index number the more this is necessary to avoid teams of glitch Pokémon, because beyond the last valid roster, Trainers will use Pokémon from the rosters of the next Trainer class, before all valid rosters are exhausted (for instance, in the Ditto glitch sub-glitch of the Trainer escape glitch this is used by altering the Attack stage of the transformed opponent (7 by default and can be 1 (-6)-13 (+6)); for instance, 6 Growls would allow the player to access that Trainer's roster 1.
***In the old man glitch however, the set of rosters for all Trainers are brought up from Trainer class 256 (using a roster index number for Trainer 256 matching the index number of the last fought Trainer) instead. As Trainer 256 is far beyond the last valid Trainer Lance (Trainer 47), fighting valid rosters this way is typically inviable (though there are exceptions such as [[arbitrary code execution]]). Players often call Trainers accessed through glitches simply [[glitch Trainer]]s, especially if they are using glitch Pokémon or a roster with an index number exceeding their last possible roster (more strictly, it could be argued Lance with glitch Pokémon isn't technically a glitch Trainer but a real Lance using a glitch roster which may include glitch Pokémon). There are further situations for encountering valid Trainers but with unintended rosters, such as encountering a Trainer after the [[ZZAZZ glitch]] (forcing the Cable Club roster), or how the [[TrainerDex/RB:052|first roster of Trainer 0x34]] is taken from $A5A5 in the SRAM (save file), rather than a constant location in ROM.
===Maps===
*Some partially unused glitch maps, such as [[AreaDex/RBY:011|Map 0x0B]] (actual unused data include potential placeholder data (such as the music for map 0x0B matching Viridian City), the unused Fly flag for going to map 0x0B, the hidden [[AreaDex/RBY:111|Max Elixer]] in [[AreaDex/RBY:111|unused but glitched map 0x6F]]).
