Glitch City is a term used by Pokémon gamers to refer to a hidden fictional city caused by a bug that occurs in the Pokémon video game Red, Blue and Yellow versions. The term Glitch City is not to be confused with Blue Hell - a more general term that refers to a non-existent area in any interactive game.
Finding Glitch City
- Go to the Safari Zone and walk around about 150 steps. (this will prevent having to walk/Surf up and down continuously later)
- When asked "Leaving early?" say No.
- In the Safari Zone, save the game, turn it off and turn it back on again.
- The man will ask if you want to join a Safari Game. Say no.
- Fly anywhere (for the Glitch City that is easiest to walk around in, fly to Cinnabar Island's east coast)
- Move for 500 steps, and then "Ding-dong!" will appear
- Leave the Safari Building and you will be in Glitch City
There is more than one Glitch City, and one can find them by going somewhere other than Cinnabar (like Cycling Road or Victory Road).This means that a player can create different glitch cities depending on where they are when the timer sounds. The Seafoam Islands and a few routes allows the player to move around; however, in most other Glitch Cities, the player will be surrounded by objects with a solid property (such as a post outside of Glitch City), and unable to walk around.
When a player views the Town Map while in Glitch City, the map will say that they are in the area they were in prior to entering Glitch City.
The most common Pokémon found in the Glitch City accessed through the Cinnabar coast are Tentacool. A player can also fish for Pokémon in Glitch City.
Going too far to the left or right will often get the player stuck in an invisible wall. If one presses Start, often the graphics and pixels of the city will change briefly.
In Pokémon Yellow the player may also see Pikachu running in random places.
The area in which the surfing part of the glitch takes place has some sort of 'unspecified' designator given by the designers which makes numerous glitches happen (including Missingno. and 'M. However, if the player is not on the Cinnabar coast and in the water just off shore when the Safari Zone "Ding-Dong" occurs, the player will be sent to the same Glitch City that that player would've been sent to if he/she had been on the coast. Also, the Glitch City "Ding-Dong" can take place anywhere (see "Location" section above) even though in some places such as Viridian City, an actual glitched city will not occur.) The music in the Glitch City accessed through the Cinnabar Coast is the same music theme as the one played on routes.
In Glitch City, pixels and graphics from different parts of the game are mixed up (see picture). The land and water can also be mixed up so sometimes it appears that the player is standing on water or surfing on land. This is usually caused by using a fishing rod or pausing the game (which causes parts of Glitch City to change). If the whole city turns to water (which is sometimes possible), the player can keep surfing forever until the player gets stuck or the game automatically shuts off. (However, a player should not surf for long distances while in Glitch City, because it can corrupt a player's game.) In the Yellow version, if one goes to the right, they will find a row with 3 9's. If they walk into this, Pikachu will disappear. When he/she walks out of it, Pikachu will follow their "recorded" path back to them.
In the Glitch City accessed through the Cinnabar Coast, in some cases players are able to surf in northern direction until they reach the barrier that normally prevents them to leave Sea Route 20 northward. When reached, however, the graphics become even more glitchy and the entire game freezes. If this is done while playing Pokémon Stadium, it will say the game has been corrupted, but the game is actually not corrupted (Pokémon Stadium just interprets it as being corrupted).
Because invisible walls that trap the player exist on the western side of the city, going north is usually the only way to escape the "normal" Glitch City. If a player goes to the westernmost "checker-board" water pattern in the city, and goes left of it one square and then right one square, this will enable the entire city to become water (when the player presses "start") and allow the player to swim north until they reach the barrier that normally cannot be crossed (causing the game to freeze). Once the player is far enough north, before reaching the northern border the player can swim east or west for a long period of time until the game freezes.
The reason the game freezes when heading too far north, east or west is because the player is surfing outside of the map and into a location that does not exist in the game's memory; as a result, the game cannot function. The only safe way out is by heading due south. It also happens in places that do exist but are completely altered. For example, when the player is able to surf considerably far north and then surfs west, they will reach where Cinnabar Island should be. However, because the game is in a glitched state it does not recognize the Island and when the player tries to go where the Island is, it will freeze. (The reason flying out of Glitch City successfully ends the Glitch is because those places are in different parts of the game's memory.)
Although the Cinnabar Island Glitch City is most famous, others are also notable. If a player goes to Cycling Road instead of the Cinnabar Coast to do the Glitch City trick, they will go to a Glitch City where they are always automatically walking downward. This is because normally the bicycle the player is on in Cycling Road automatically goes downward. Also, if said player tries to get on their bike it will say "You can't get off here," which is the normal message displayed when a player is trying to get off their bike on Cycling Road. It should be noted that a player goes to the southern-most point of cycling road where it is not sloped, that player will be sent to a different glitch city where they can't move at all. While doing the Glitch City glitch, if the player goes to Victory Road instead of Cinnabar Island, the Glitch City created will contain statues from the Indigo Plateau/Victory Road. In the Yellow version, if the player goes to Route 13 while doing the Glitch City trick, the player will be transported to a Glitch City where any move the player makes will send him or her to the Saffron City gym. Once he or she leaves the gym, the player will be in a completely different Glitch City.
The only way out of Glitch City is to fly out, so if one saves the game, one should make sure there is a Pokémon that can fly out. As a precaution, players going to Glitch City should never save the game in Glitch City, even if they have a Pokémon that can fly out. (For example, if any player saves the game in Glitch City and they realize they do not have a Pokémon that can fly out, they will be stuck in Glitch City forever.)
The Glitch Cities found in the Yellow version are different to those that are found in the Red and Blue versions.
The reason that this glitch takes place is, when a player performs the glitch to leave Safari Zone, the game still has its timer on. When the timer ends, it sends the player to the gatehouse. The reason for glitch cities is because the warp in the Safari Zone Gate are values FF. This tells the game to teleport the player to the last city or route he/she was at. Another part of the Warp is a "Warp-to", which tells the game which warp on the map to warp the player to. Each map has a certain number of warps, and the warp in the memory tells the game to take the player to the fourth warp in the map. Although, some routes/cities don't have 4 warps, in fact, some routes have no warps. So when the game is told to take a player to a warp that doesn't exist, it gets confused, and takes them to a glitched area.
Prevention of Glitch City in later games
The Safari Zone was not included in the Gold, Silver and Crystal versions -- regardless of whether or not it was deliberately removed because of Glitch City (which has lead to much speculation but nothing is known for sure), the removal of the Safari Zone nonetheless prevents Glitch City from occurring the way it does in the Red, Blue and Yellow versions. However, there is a method of getting to a glitched area that is very similar in appearance to Glitch City. The player must use a GameShark to encounter a ?????. When it is defeated or captured, the player will be in the "GSC Glitch City".
In Pokémon Ruby, Sapphire, and Emerald, the player must exit the Safari Zone by using the Start menu and selecting "Retire." A warden also goes outside and blocks the door, so the player cannot return to the Safari Zone lobby while using the Safari Zone.
A way to reach the closest thing there is to Glitch City in Pokémon Gold and Silver without using the GameShark is to listen to the cry of any Machop (including the Pokédex and the ones in Goldenrod Mart) then immediately use the coin case. It is also possible to use this trick with another Pokémon to make the coin case say Coins: Which move? instead of Coins: (number of coins). Once a player activates this glitch, the game will automatically "reset" and the opening sequence will be glitched up and the colors inverted at certain points. Once the player begins gameplay, the buildings are all blue and red, the ground is multi-colored, and the battle screen colors are different. The game will also be much slower than usual.
