All maps in [[Generation IV]] are broken up into square "sections" or "chunks" 32 tiles by 32 tiles across. At any given time, only four sections are loaded and visible: the section the player is currently in as well as two sections orthogonally away and one diagonally away, depending on which {{wp|Quadrant (plane geometry)|quadrant}} of the current section the player is in. (For example, if the player is standing in the northwest quadrant of their current section, the sections to the north, west, and northwest will be loaded.) "Load lines" exist halfway across each section at the boundaries between quadrants, so named because when the player crosses over one, the sections in that direction are loaded into memory, while the sections behind the player are unloaded. Through this, the overworld appears seamless.

Using the [[Bicycle]] in the fourth gear, however, can cause the player to move too fast for the game to load the areas properly, especially if one changes direction several times while near the intersection of two load lines, thus loading and unloading multiple sections over and over nearly simultaneously. Doing so triggers a {{wp|race condition}} bug, causing sections to load improperly. The effects can vary from a [[game freeze]], invisible walls, a completely black area, a completely white area, a change in the {{wp|Z-axis}} location, or even a completely different section fully loading in the wrong place.

The distortion caused by tweaking can be solved easily by crossing a load line away from the distortion, causing it to unload. When the section is loaded again, it will be normal. It can also be solved by looking at a different menu screen such as the Pokédex; upon closing out of the menu, the areas will be properly reloaded.

While tweaking using the bicycle in the fourth gear is the most common method to perform tweaking, the same effects can also occur using only the third gear, although its applications are not as versatile. It is even possible for some limited effects to occur simply by running (as well as {{m|Surf}}ing in {{v2|Platinum}}, which is at the same speed), mainly invisible walls and Z-axis changing rather than more drastic changes.

===Shortcuts===
===Shortcuts===
Depending on the layout of a section, it may be possible to tweak in such a way so as to load a walkable area (either black or visible) onto a section that does not normally contain walkable surfaces. This allows for a number of shortcuts, such as skipping [[Tohjo Falls]] and therefore {{HM|07|Waterfall}} in {{game|HeartGold and SoulSilver|s}} by loading a walkable area onto the section where the [[ledge]] on [[Route 27]] would normally be. In sections containing buildings that are blocked off by NPCs, it is possible to enter them by tweaking a Z-axis change, allowing the player to walk under or over the tile the NPC would normally occupy. Three examples of minor shortcuts or sequence breaks using this method include obtaining access to [[Mystery Gift]] in {{game2|Diamond|Pearl|Platinum}} before the first badge by bypassing the clown blocking the [[Jubilife TV]] front door, completing [[Azalea Gym]] before [[Slowpoke Well]] by bypassing the [[Team Rocket]] Grunt in front of the Gym (though this by itself does not allow Slowpoke Well or Rocket Executive [[Proton]] to be skipped entirely, since the game does not trigger the {{p|Farfetch'd}} event that gives the player {{HM|01|Cut}} unless Proton has been defeated), and gain access to the [[Goldenrod Gym]] early, which is a crucial part in glitched speedruns.

Traveling a multiple of 65,536 steps in the void will cause the game to no longer display only black, but rather start copying the map data of normal areas due to an overflow{{fact}} after attempting to load data past {{wp|4294967295#In_computing|4,294,967,296}} bytes (each map tile takes up 65,536 bytes).

As part of the paths to access Darkrai and Shaymin, the player is required to save the game in the void, so the same risks associated with the [[Surf glitch]] occur here, such as becoming trapped without a method of escape. It is also possible for, in the worst possible circumstance, the game to immediately freeze upon loading the save file, forcing a new game to be started. This can be tested for however by opening and closing an option on the menu such as the bag (usually referred to as a Black Screen Of Death test), as the game will freeze upon closing the selected menu option, preventing your save from being damaged.

After the discovery of the Darkrai and Shaymin paths, it was believed (though not conclusively proven) that the [[Hall of Origin]] was inaccessible through this glitch, as it is a closed-off indoor area without a single accessible entry warp, thereby making it almost impossible to safely locate in the void compared to outdoor areas and indoor areas with many warps such as [[Turnback Cave]]. It was also known that, unlike Newmoon Island and Flower Paradise, simply finding the Hall of Origin would not allow the player to battle {{p|Arceus}}, due to a set of reasons involving map scripts as detailed [[Hall of Origin#Trivia|here]]. Due to the combination of these two factors, it was believed impossible to catch Arceus through the void glitch for several years.

The [[Pal Park Retire glitch]] was documented soon afterward, allowing the player to manually activate the script that causes the player to challenge Arceus, finally enabling Arceus to be caught. The currently documented method to catch Arceus involves reaching the Hall of Origin map while still in the void; there is currently no documented way to see the full, visible Hall of Origin (the way it appears after using the Azure Flute).

In {{game|Platinum}}, {{game|HeartGold and SoulSilver|s|HeartGold, and SoulSilver}}, the void is filled with invisible walls that will trap the player if they go more than a few steps into the void, making it no longer legitimately<!-- definition: no external devices --> possible to navigate through its areas, though the void itself is still possible to enter. Currently the only known way to bypass these invisible walls and proceed through the void is with a "walk through walls" [[cheat]] code. As a corollary, a "walk through walls" cheat code is the only way to see "Fake Sinnoh" in Platinum, and "Fake Kanto/Johto" at all (in HeartGold and SoulSilver). In addition, in Platinum, Darkrai and Shaymin will not appear in their respective areas unless the player has obtained the proper [[event item]].

The void glitch, when using the wrong warp method, can also force the player through walls when a certain amount of mistakes are made. This is because traversing the void messes with the RAM. An example would be in Diamond and Pearl. Attempting the wrong warp glitch, but opening the Explorer Kit 3 times instead of 1, would teleport the player to his/her bedroom, and when entering any Pokémon center and going up the left escalator to access its upper part, an unknown error will visibly shove the player into the void outside of the PMC. It is unknown why this happens (other than by creating new code in the RAM by using the void) but it appears that visibly, the character simply walks through the wall.

Reason: Look further into the name of the glitch among Japanese fans to see if there is an original term
An example of a successful tweak.

Tweaking is a glitch exclusive to the core series Generation IV games that causes the game to improperly load the graphics of an area. It is also sometimes referred to as holepunching to commemorate its discoverer, a GameSpot forums member by the username of "Holepunch".

Cause

An example of a tweak where a visibly incorrect chunk is loaded. No Pokémon will be encountered here.

All maps in Generation IV are broken up into square "sections" or "chunks" 32 tiles by 32 tiles across. At any given time, only four sections are loaded and visible: the section the player is currently in as well as two sections orthogonally away and one diagonally away, depending on which quadrant of the current section the player is in. (For example, if the player is standing in the northwest quadrant of their current section, the sections to the north, west, and northwest will be loaded.) "Load lines" exist halfway across each section at the boundaries between quadrants, so named because when the player crosses over one, the sections in that direction are loaded into memory, while the sections behind the player are unloaded. Through this, the overworld appears seamless.

Using the Bicycle in the fourth gear, however, can cause the player to move too fast for the game to load the areas properly, especially if one changes direction several times while near the intersection of two load lines, thus loading and unloading multiple sections over and over nearly simultaneously. Doing so triggers a race condition bug, causing sections to load improperly. The effects can vary from a game freeze, invisible walls, a completely black area, a completely white area, a change in the Z-axis location, or even a completely different section fully loading in the wrong place.

The distortion caused by tweaking can be solved easily by crossing a load line away from the distortion, causing it to unload. When the section is loaded again, it will be normal. It can also be solved by a graphic refresh, such as opening any menu that takes up both screens and then closing out.

While tweaking using the bicycle in the fourth gear is the most common method to perform tweaking, the same effects can also occur using only the third gear, although its applications are not as versatile. It is even possible for some limited effects to occur simply by running (as well as Surfing in Platinum, which is at the same speed), mainly invisible walls and Z-axis changing rather than more drastic changes.

Patterns

Tweaking pattern example.png
050Diglett.png This section is incomplete.
Please feel free to edit this section to add missing information and complete it.
Reason: writeup quality; diagonal displacement with fast bike (necessary in HGSS)

In the image to the right, the blue lines represent load lines (thus this is the center of a section) and the numbers represent tiles that the player can walk on. (For example, taking one step east from 1 will bring the player to 2, crossing a load line in the process.)

In all patterns detailed below, the patterns can be flipped and rotated to produce displacements in different directions.

Orthogonal displacement

"3124343" (fast bike): Nicknamed a "zorch" after its discoverer, this was the first reliable tweaking pattern ever discovered. It causes the section east of the player to load as a black area onto the section west of the player. Obsoleted by the later-discovered "shortzorch".

"42121" (fast bike): Nicknamed a "shortzorch", this has the same effect as a zorch.

"31213" (fast bike, HG/SS): Causes the section east of the player to fully (visibly) load onto the section west of the player. This pattern causes a crash in Diamond, Pearl and Platinum because of a difference in bike speeds.

"42131" (slow bike, running and surfing in Platinum and HG/SS): Causes the section east of the player to become either a black, walkable abyss with the same collision and unloaded or partially loaded NPCs (slow bike), an unwalkable but visible abyss with unloaded or partially loaded NPCs (running) or a walkable, visible section with unloaded or partially loaded NPCs (running). Both effects caused by this pattern when running can also be done using the "1242131" pattern.

"421312D21" (fast bike): Causes the section south of the player to fully (visibly) load onto the section north of the player. The "D" in this pattern represents the tile to the right of 2.

Diagonal displacement

"12421" (slow bike): Causes the section northeast of the player to fully (visibly) load onto the section northwest of the player. Possible with only the third gear bike since sections diagonal to the player are farther away and load last, making it easier to interrupt the process.

"1242131" or "13431" (slow bike): Causes the section southwest of the player to visibly load onto the section northwest of the player as well as an unwalkable abyss to the north of the player if you're using the "1242131" pattern.

Exploitation

Shortcuts

Depending on the layout of a section, it may be possible to tweak in such a way so as to load a walkable area (either black or visible) onto a section that does not normally contain walkable surfaces. This allows for a number of shortcuts, such as skipping Tohjo Falls and therefore HM07 (Waterfall) in Pokémon HeartGold and SoulSilver by loading a walkable area onto the section where the ledge on Route 27 would normally be. In sections containing buildings that are blocked off by NPCs, it is possible to enter them by tweaking a Z-axis change, allowing the player to walk under or over the tile the NPC would normally occupy. Three examples of minor shortcuts or sequence breaks using this method include obtaining access to Mystery Gift in Pokémon Diamond, Pearl, and Platinum before the first badge by bypassing the clown blocking the Jubilife TV front door, completing Azalea Gym before Slowpoke Well by bypassing the Team Rocket Grunt in front of the Gym (though this by itself does not allow Slowpoke Well or Rocket Executive Proton to be skipped entirely, since the game does not trigger the Farfetch'd event that gives the player HM01 (Cut) unless Proton has been defeated), and gain access to the Goldenrod Gym early, which is a crucial part in glitched speedruns.

These types of shortcuts are possible in all Generation IV games.

Void glitch

The void glitch is a specific application of the tweaking glitch only useful in Pokémon Diamond and Pearl. First, the player must tweak a black area onto a section that would normally contain buildings, making it possible to walk through their improperly loaded walls. Then, by standing exactly one tile above the entrance to a building, reloading the area, and walking south, the player can end up on the interior map of the building, but in the black void area around the normally accessible portion, similar to the Surf glitch. As with the Surf glitch, it is then possible to navigate through the interconnecting area of this void to normally inaccessible locations, such as Newmoon Island and the Flower Paradise where the event-exclusive Darkrai and Shaymin reside.

Traveling a multiple of 65,536 steps in the void will cause the game to no longer display only black, but rather start copying the map data of normal areas due to an overflow[citation needed] after attempting to load data past 4,294,967,296 bytes (each map tile takes up 65,536 bytes). Only the visual data is loaded like this; almost everything can still be walked through just as in the rest of the void. These areas are nicknamed "Fake Sinnoh"DPPt or "Fake Johto/Kanto"HGSS. 'Fake' regions continue to repeat every 65,536 steps and are about an hour apart when traveling on the Bicycle in fast gear.

As part of the paths to access Darkrai and Shaymin, the player is required to save the game in the void, so the same risks associated with the Surf glitch occur here, such as becoming trapped without a method of escape. It is also possible for, in the worst possible circumstance, the game to immediately freeze upon loading the save file, forcing a new game to be started. This can be tested for, however, by opening and closing an option on the menu such as the Bag (usually referred to as a Black Screen of Death test), as the game will freeze upon closing the selected menu option, preventing the save file from being damaged.

Other notable areas known to be accessible through this glitch include the Hall of Fame, Giratina's room in Turnback Cave, Valor Cavern, Acuity Cavern, the second to last room in Team Galactic HQ, Spear Pillar, and any route, town or city in the game either by using Fake Sinnohs or the Battle Tower void.

After the discovery of the Darkrai and Shaymin paths, it was believed (though not conclusively proven) that the Hall of Origin was inaccessible through this glitch, as it is a closed-off indoor area without a single accessible entry warp, thereby making it almost impossible to safely locate in the void compared to outdoor areas and indoor areas with many warps such as Turnback Cave. It was also known that, unlike Newmoon Island and Flower Paradise, simply finding the Hall of Origin would not allow the player to battle Arceus, due to a set of reasons involving map scripts as detailed here. Due to the combination of these two factors, it was believed impossible to catch Arceus through the void glitch for several years. A method to find the Hall of Origin was not discovered until January 2017, by relying on relatively extensive methods to be able to dynamically control the layout of areas in the void[1]. The Pal Park Retire glitch was documented soon afterward, allowing the player to manually activate the script that causes the player to challenge Arceus, finally enabling Arceus to be caught. The currently documented method to catch Arceus involves reaching the Hall of Origin map while still in the void; there is currently no documented way to see the full, visible Hall of Origin (the way it appears after using the Azure Flute).

In Pokémon Platinum, HeartGold, and SoulSilver, the void is filled with invisible walls that will trap the player if they go more than a few steps into the void, making it no longer legitimately possible to navigate through its areas, though the void itself is still possible to enter. Currently the only known way to bypass these invisible walls and proceed through the void is with a "walk through walls" cheat code. As a corollary, a "walk through walls" cheat code is the only way to see "Fake Sinnoh" in Platinum, and "Fake Kanto/Johto" at all (in HeartGold and SoulSilver). In addition, in Platinum, Darkrai and Shaymin will not appear in their respective areas unless the player has obtained the proper event item.

The void glitch, when using the wrong warp method, can also force the player through walls if they complete it wrong. This is because traversing the void messes with the RAM. An example would be in Diamond and Pearl. Attempting the wrong warp glitch, but opening the Explorer Kit 3 times instead of 1, would teleport the player to their bedroom, and when entering any Pokémon Center and going up the left escalator to access its upper part, an unknown error will visibly shove the player into the void outside of the Pokémon Center. This happens because the game erroneously plays the animation of the player leaving the Union Room, causing the player to walk through the wall. This can be fixed by speaking to the receptionist at the Global Trade Station and getting to the prompt where it asks whether the player wants to connect to Nintendo WFC (without actually needing to connect), but going into the GTS should fix the Pokémon Center issues.

Another glitch to be noted of is that if the player hasn't visited the Underground yet, the cutscene in which Roark introduces the player to the Underground plays, which normally would play under certain circumstances, but since the player is in a section of the game where the RAM is stored, the game will freeze due to the fact that it shouldn't be able to play there.

Alternate Jubilife City theme

If the player opens the bag in a location marked as "Turnback Cave", the next "Jubilife City" location will have no music. After that, the next time the player reaches a "Jubilife City" location, an alternate version of the usual Jubilife City theme will play instead. The alternate track will persist if the player travels to the real Jubilife City using Fly.
