The '''Old Man Trick''' allows one to capture high-level or glitch Pokémon on the eastern Cinnabar Island strait. It is sometimes called the MissingNo. Glitch.  
+
The '''old man trick''' (also known as the '''Missingno. glitch''', although Missingno. is not the only Pokémon that can be encountered using this trick) 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.
-
This glitch was fixed in some foreign versions of Red and Blue, such as the Spanish versions, making MissingNo. only possible to find through the Mew Glitch instead.
+
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':
 +
 
 +
*The tiles directly east of Cinnabar Island.
 +
*The tiles east of the right-most [[bp:Seafoam Islands|Seafoam Islands]] cave.
 +
*The left-facing shore tiles in a Sea Route 19 [[Glitch City (Red, Blue, Yellow)|Glitch City]].
 +
 
 +
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]].

 +
2. Fly to Cinnabar Island or Fuchsia City. Do not leave Viridian City before doing this.
 +
 
 +
3. If you chose Cinnabar Island, Surf along the eastern coast until you encounter a wild Pokémon. If you chose Fuchsia City, go to the shore tiles right of the east-most Seafoam Islands cave.
 +
 
 +
[[Image:Oldman2.png]]
 +
 
 +
If using a Spanish or Italian version of Red/Blue, remember to walk across the coast using the [[walk through walls trick (ledge method)]], instead of surfing on it, or you'll only get wild Tentacool.
 +
 
 +
== Cause ==
 +
The old man trick 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.
 +
#The player's name is temporarily changed to "OLD MAN" during the old man's catching demonstration, and then changed back to what it was before. In the process, the player's name is stored in memory starting from the 'grass encounter rate' memory address, at $D887. After the battle ends, the value at $D887 is changed back to normal, but what follows it (grass Pokémon and level data) starting from $D888 is not.
 +
 
 +
Saving the player's name here would normally not be a problem, due to the data being updated when you enter a new route, but it is not updated when flying to Cinnabar Island or Fuchsia City, and the first event enables the 'name data Pokémon' to be encountered.
 +
 
 +
=== Encounters ===
 +
In at least the English version of Pokémon Red and Blue, the encounters on the left-facing shore tiles work as such:
 +
 
 +
*The second, fourth, sixth, eighth and tenth characters determine the level of a Pokémon. (the [[identifier]] of the letter is used)
 +
*The third, fifth, seventh, ninth and eleventh characters determine the type of Pokémon species or Trainer for values greater than 199. (the identifier of the letter is used)
 +
 
 +
The characters are case-sensitive.
 +
 
 +
Example:
 +
 
 +
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 Big HEX List], as well as in the table below:

===Default name yields===
 +
If the player's name was selected from one of the choices at the beginning of the game (e.g. RED), extra Pokémon can be encountered that wouldn't appear if they had entered the same name manually.
 +
 
 +
This is because internally extra letters appear in these names after the end (hex:50) characters. The names are actually as they appear in the table below.
 +
 
 +
{| border="1"
 +
!Red
 +
!Blue
 +
|-
 +

 +
|GARY(50)JOHN(50)N
 +
|-
 +
|JACK(50)NEW(7F)NA
 +
|JOHN(50)NEW(7F)NA
 +
|}
 +
 
 +
As none of these names have a no hex:00 character in letters 3, 5, 7, 9 or 11, hex:00 ([[GlitchDex/RB:000|'M (00)]]) cannot be encountered with a default name, at least in the English versions.
 +
 
 +
The next table below shows what default names give what Pokémon.

3. Surf along the eastern coast of Cinnabar Island until you encounter a wild Pokémon.
+
===Extra Pokémon from the German version===
 +
Exclusively to the German version, the letters Ä (hex:C0), Ö (hex:C1), Ü (hex:C2), ä (hex:C3), ö (hex:C4) and ü (hex:C5) can be entered on the 'your name' screen, and these can be used to encounter glitch Pokémon with index numbers from 192-197, but the hex:C2 and hex:C5 glitch Pokémon (may) freeze the game on encounter.
-
[[Image:oldman2.jpg]]
+
===Glitch Trainers===
 +
The glitch Trainers encountered through the old man glitch always have the same rosters.
-
== Additional Information ==
+
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.
-
[[Image:Oldmanmissingno2.png|200px|thumb|right|One of the weird MissingNo. variations. It appears if you have a ''w'' in the right place in your name.]] As the player is Surfing, he should encounter Pokémon that normally wouldn't be seen in the ocean, some of which are over Level 100. Eventually, the player will encounter a Glitch Pokémon called either 'M or MissingNo.
+
Below are the first ten glitch Trainer rosters, thanks to Glitch City Laboratories forums user TheZZAZZGlitch:
-
MissingNo. and 'M are prized mainly because encountering one gives the player 128 of the sixth item on your item list. This trick can therefore be used to give the player almost infinite Master Balls, Rare Candies, etcetera, by using it again whenever the supply runs low.

1. When creating the map of which Pokémon appears where, the programmers made a mistake. The strip of land making up the Cinnabar Island Strait was programmed to be a place where wild Pokémon could appear, but they forgot to specify WHICH Pokémon could appear there! Whenever you enter a new area, the data for "What Pokémon appear where" is overwritten with the specific data for that area. However, because no data is specified for the Cinnabar Island Strait, the previous data will remain, enabling you to evidentially catch Pokémon there from the last area you visited (this is what causes the [http://bulbapedia.bulbagarden.net/wiki/Kanto_Safari_Zone Safari Zone] trick to take place).
+
The old man trick 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.
-
2. When you watch the Old Man's demonstration, the picture and text change from your name to "Old Man". For this to happen, the programmers changed the variables given to your name so the picture and text can show up as "Old Man". These are stored in the byte containing the data for "What Pokémon appear where" as this was the place the programmers would be a safe place to store them until the demonstration finishes, and they would be overwritten when you entered a new place anyway, but when you go directly from the Old Man's demonstration to the Cinnabar Island Strait, the data won't be overwritten as it should, leaving your name's variables in the "What Pokémon appear where" byte. None of these variable's HEX Values make sense, so it would fit that the Pokémon encountered there would not make sense. The game brings up an empty HEX Value so Missingno appears.

Latest revision as of 17:09, 29 July 2014

Bulbapedia also has an article about Old man trick.
Wild MISSINGNO. appeared!

'Missingno. glitch' redirects here, for the glitch Pokémon or 'placeholder entry', see Missingno.

The old man trick (also known as the Missingno. glitch, although Missingno. is not the only Pokémon that can be encountered using this trick) is a well-known derivative of the left-facing shore tile glitch in Pokémon Red and Blue, that allows one to capture high-level or glitch Pokémon, based on the player's name, as well as glitch Trainers.

It is performed by watching the old man of Viridian City's catching demonstration, using Fly to go to Cinnabar Island or Fuchsia City and then surfing on one of the following 'left-facing shore tiles':

  • The tiles directly east of Cinnabar Island.
  • The tiles east of the right-most Seafoam Islands cave.
  • The left-facing shore tiles in a Sea Route 19 Glitch City.

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 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.

Contents

Requirements

  1. A Red or Blue Version Pokémon game that has been played up to Cinnabar Island or Seafoam Islands.
  2. A Pokémon that knows Fly.
  3. A Pokémon that knows Surf.

Steps

1. Talk to the Old Man at Viridian City who shows you how to catch Pokémon. Say no to his question and watch his demonstration.

Oldman1.png

2. Fly to Cinnabar Island or Fuchsia City. Do not leave Viridian City before doing this.

3. If you chose Cinnabar Island, Surf along the eastern coast until you encounter a wild Pokémon. If you chose Fuchsia City, go to the shore tiles right of the east-most Seafoam Islands cave.

If using a Spanish or Italian version of Red/Blue, remember to walk across the coast using the walk through walls trick (ledge method), instead of surfing on it, or you'll only get wild Tentacool.

Cause

The old man trick is a combination of two events.

  1. 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.
  2. The player's name is temporarily changed to "OLD MAN" during the old man's catching demonstration, and then changed back to what it was before. In the process, the player's name is stored in memory starting from the 'grass encounter rate' memory address, at $D887. After the battle ends, the value at $D887 is changed back to normal, but what follows it (grass Pokémon and level data) starting from $D888 is not.

Saving the player's name here would normally not be a problem, due to the data being updated when you enter a new route, but it is not updated when flying to Cinnabar Island or Fuchsia City, and the first event enables the 'name data Pokémon' to be encountered.

Encounters

In at least the English version of Pokémon Red and Blue, the encounters on the left-facing shore tiles work as such:

  • The second, fourth, sixth, eighth and tenth characters determine the level of a Pokémon. (the identifier of the letter is used)
  • The third, fifth, seventh, ninth and eleventh characters determine the type of Pokémon species or Trainer for values greater than 199. (the identifier of the letter is used)

The characters are case-sensitive.

Example:

The name 'Abwayax' would give a level 'b' (161) 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) '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 Big HEX List, as well as in the table below:

Default name yields

If the player's name was selected from one of the choices at the beginning of the game (e.g. RED), extra Pokémon can be encountered that wouldn't appear if they had entered the same name manually.

This is because internally extra letters appear in these names after the end (hex:50) characters. The names are actually as they appear in the table below.

Red Blue
RED(50)ASH(50)JAC BLUE(50)GARY(50)J
ASH(50)JACK(50)NE GARY(50)JOHN(50)N
JACK(50)NEW(7F)NA JOHN(50)NEW(7F)NA

As none of these names have a no hex:00 character in letters 3, 5, 7, 9 or 11, hex:00 ('M (00)) cannot be encountered with a default name, at least in the English versions.

The next table below shows what default names give what Pokémon.

Name Level 1 Pokémon 1 Level 2 Pokémon 2 Level 3 Pokémon 3 Level 4 Pokémon 4 Level 5 Pokémon 5
RED 132 Mewtwo 80 Golduck 146 Missingno. (hex:87) 80 Missingno. (hex:89) 128 Golbat
ASH 146 Missingno. (hex:87) 80 Missingno. (hex:89) 128 Golbat 138 Missingno. (hex:50) 141 Snorlax
JACK 128 Golbat 138 Missingno. (hex:50) 141 Snorlax 150 Missingno. (hex:7F) 141 Golduck

Extra Pokémon from the German version

Exclusively to the German version, the letters Ä (hex:C0), Ö (hex:C1), Ü (hex:C2), ä (hex:C3), ö (hex:C4) and ü (hex:C5) can be entered on the 'your name' screen, and these can be used to encounter glitch Pokémon with index numbers from 192-197, but the hex:C2 and hex:C5 glitch Pokémon (may) freeze the game on encounter.

Glitch Trainers

The glitch Trainers encountered through the old man glitch always have the same rosters.

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:
