'''Missingno. glitch' redirects here, for the glitch Pokémon or 'placeholder entry', see [[Missingno.]]''
 
The '''old man trickglitch''' (also known as the '''Missingno. glitch''', although Missingno. is not the only Pokémon that can be encountered using this trickglitch) is a well-known derivative of the [[left-facing shore tile glitch]] in {{RB}}, that allows one to capture high-level or [[glitch Pokémon]], based on the player's name, as well as [[glitch Trainer]]s.
 
It is performed by watching the old man of [[bp:Viridian City|Viridian City]]'s catching demonstration, using Fly to go to [[bp:Cinnabar Island|Cinnabar Island]] or [[bp:Fuchsia City|Fuchsia City]] and then surfing on one of the following 'left-facing shore tiles':
Line 14 ⟶ 13:
*The left-facing shore tiles in a Sea Route 19 [[Wrong warp Glitch City|Safari Zone wrong warp Glitch City]].
 
== Code changes ==
The previous Pokémon list glitch seemingly does not exist in all the Japanese versions, or Pokémon Yellow, as the tiles east of Cinnabar Island and east of the Seafoam Islands cave apparently never give wild Pokémon.
 
This glitch was partially fixed in the Italian and Spanish versions of Red and Blue, as [[bp:Tentacool|Tentacool]] appear if the player surfs on a left-facing shore tile. This can be worked around with by walking on the tiles; not surfing, by using the [[walk through walls trick (ledge method)]]; which is a derivative of the [[Safari Zone exit glitch]].

== Cause ==
The old man trickglitch is a combination of two events.
 
#In English and European versions, surfing (or walking on, if necessary) on one of the shore tiles described in the introduction of this article brings up the previous list of Pokémon in the grass.
Line 62 ⟶ 81:
The name 'Abwayax' would give a level 'b' (161) [[Missingno.|Kabutops Fossil Missingno.]] ('w', hex:B6), a level 'a' (160) Ghost Missingno. ('y', hex:B8), a level 'a' (161) Aerodactyl Fossil Missingno. ('x', hex:B9) and a level 80 (hex:50) [[GlitchDex/RB:000|'M (00)]], due to 50 and 00 characters normally directly following a valid name entry name.
 
The identifiers of the characters can be found on the [http://glitchcity.info/biglist.htm[The Big HEX List]], as well as in the table below:

===Glitch Trainers===
Since the old man glitch allows fighting trainers on the "wild encounter" code path, the enemy parameters are not properly initialized. Hence:
The glitch Trainers encountered through the old man glitch always have the same rosters.
* The glitch Trainers encountered through the Old man glitch always have the same rosters as [[TrainerDex/RB:000|Trainer class 0]].
 
* The roster loaded depends on the roster number of the last trainer fought.
The roster loaded depends on the memory address D05D. Normally this value is 00, but encountering a Trainer writes that Trainer's roster value to it. This value is kept after battle, so more than one type of old man trick Trainer can be battled.
 
Below are the first ten glitch Trainer rosters, thanks to Glitch City Laboratories forums user TheZZAZZGlitch:

== Item duplication ==
''See also: [[Infiniteinfinite itemsitem glitches (disambiguation)]]''.
 
The old man trickglitch is arguably the easiest and most reliable way of encountering [[Missingno.]] and [[GlitchDex/RB:000|'M (00)]]. As their invalid [[Glitch Pokédex flag|Pokédex flag]] (#000 but effectively #256) means that encountering or capturing Missingno. and 'M adds a quantity of 128 to the sixth item in the player's bag if the quantity is less than 128, it is ideal for duplicating items, such as Rare Candies and Master Balls.
 
== Item conversionmutation ==
''See also: [[item conversionmorphing glitches (disambiguation)]]''.
 
The old man trickglitch can be used to convert the fourth item into a few other items if the player has a name that lets them encounter a Trainer, and the identifier of the fourth item is not $1X, $3X, $5X, $7X, $9X, $BX, $DX, or $FX. This requires fighting a Rocket on Silph Co.'s 11F first.
 
The Trainer has level 250 Pokémon, and may use a [[Super Glitch]] inducing move, so a high level Pokémon with a one-hit KO move, X Speeds and an X Accuracy is recommended as it's otherwise impossible to defeat all of their Pokémon in one hit, and after the Super Glitch effect happens, the Trainer can send out the Pokémon that just fainted.
