Super Glitch

The subject of this article has no official name. The name currently in use is a fan designator; see below for more information.

---

Super Glitch is the nickname for a large amount of volatile glitch moves that exist in hexadecimal slots A6 to C3 in Pokémon Red and Blue. These moves generally have either no name, a number of glitchy symbols as a name, or the name of a Pokémon in one's party as its name. Super glitch effects can also occasionally be caused by the move --.

Effect

Super Glitch can cause some rather strange effects. The most famous scenario is a chain of events starting with the music slowly fading out before stopping altogether known as the 'TMTRAINER effect'. The opponent's name then changes to "TMTRAINER" followed by several lines of glitch dialogue, and the HP of his or her Pokémon would rise to a very large value which is often larger than the amount of total HP that the opponent Pokémon has, which causes the HP bar to stretch and wrap around the screen. It will display that the enemy Pokémon is poisoned, but the game will state that it is frozen solid, followed by the enemy Pokémon becoming hurt by a burn. This burn will often deplete all of the enemy Pokémon's health, causing the giant HP bar to loop several times before all the HP is depleted, causing it to faint. If the battle is won before the game freezes, the glitch Pokémon that used Super Glitch may grow to a random level (sometimes even exceeding level 100). Also, sometimes many random Pokémon not part of the player's team evolve right after a battle. On such cases, Pokémon that cannot evolve can evolve into themselves.

On occasion, a player may return to the game after a battle in which Super Glitch was used, but everything will be severely messed up. It will appear as if some Pokémon are poisoned in the player's team as every few steps a Pokémon faints. However, these Pokémon have glitchy names and were never part of the player's team before the battle. Some positions of the map will be glitchy and volatile, as if parts of Glitch City merged with the regular map. The player's name will have changed to a scrambled string of symbols. The player will be unable to view his or her Pokémon (if the Pokémon option is selected in the menu, a blank screen will show from which one can't escape) and hence it becomes impossible to Surf or Fly. Pokémon will disappear out of the Pokédex after taking a few steps. The music everywhere (except in battle) becomes eerie and glitched. The game may unexpectedly freeze at any point. The player may also randomly get stuck.

Super Glitch's index number only changes the probability of the move causing glitch effects, and it does not change the obtained effect itself - the effects are the same for every Super Glitch index and for every Super Glitch-related move.

Cause

Super Glitch moves have no defined names, so the game looks for them past the actual move name list, and takes an unpredictably chosen RAM fragment as the name of the move. The problem occurs when the game tries to display such a name on the screen - the programmers assumed that each move name always ends with an end of string symbol, so the copy operation continues until it is found. The random move name that is picked from the memory may not have such a symbol, so the game copies too many bytes, overwriting important memory areas behind the text buffer.

In the memory layout of the game, a screen buffer is located directly after the text buffer. The screen buffer is a memory fragment where the game saves how your screen looked like before opening a full-screen menu - it exists so the screen contents can be restored after the menu has been closed. Opening any full-screen menu causes the buffer to be replaced with the current screen contents. It means that the values Super Glitch writes depend on what was recently displayed on the screen, and by opening any full screen menu and refreshing the screen copy, it is possible to control how Super Glitch corrupts the RAM. Also, the number of characters the move names before the Super Glitch have will offset the location where memory corruption starts.

The starting location of Super Glitch's memory corruption can be calculated from an equation: StartingLocation = D0E1₁₆ + MoveLengths + NumberOfMovesBeforeSuperGlitch.

To find the memory address where the n-th screen tile will be written, use the formula: StartingLocation + n.

Issues and prevention

As the Super Glitch corruption is caused by viewing the name of the move, if a Pokémon as much as attempts to learn the move—as many Glitch Pokémon do—the RAM may be corrupted. This can be avoided by standing on a certain tile on the ground floor of Celadon Mansion and opening the Start Menu. Having last opened the menu there—taking care not to touch it afterwards—the player can view Super Glitch move names without any adverse effects on the game. This is very useful as it allows a careful player to train Pokémon that learn the move, while avoiding the RAM corruption

Misconceptions

Something important to note is that it is the move that is dangerous, not its users. For example ゥ .4, which knows Super Glitch as a starting move, is mistakenly believed to be extremely dangerous to one's game and save file. However, ゥ .4 as a species is no more dangerous than Missingno. or 'M (00). In fact, a ゥ .4 acquired by trading a p^P_K^M_Np' ' from Pokémon Yellow will pose no threat whatsoever to the game, and a ゥ .4 that has forgotten Super Glitch is completely safe. Though obviously, a wild ゥ .4 will still pose a significant threat, as it will know Super Glitch.

Trivia

• Super Glitches have a tendency to change player's Pokémon into HEX 7F MissingNos, change big amount of moves to Waterfall, and give some Pokémon level 127. It happens because tile 7F is the space character, which is widely used on screen to display textboxes and aligned lists.
• The only factor preventing the player from saving the game after using Super Glitch is the corrupted name. So with enough luck, Super Glitch may bring a name with an end of string symbol, and the player would be eventually able to save the corrupted data.
• There exist special overworld locations, which after being converted to on-screen tiles, may terminate the Super Glitch name and render it harmless. Such a spot is located 3 steps below stairs in Celadon Condominiums 1F.
• Contrary to popular belief, using a Super Glitch move isn't any more destructive than selecting it in the fight menu.
• Super Glitches may sometimes reveal certain unused data portions, like beta battle systems in Pokémon Yellow or the NORTH/WEST boxset.
• Super Glitch index A6 is especially dangerous, since its invalid name points to a constant memory location, which always causes memory corruption. Index A7 however, will always display in-battle as "qq" and will not cause any side-effects, while it will cause memory corruption while viewed in the overworld.
