Bulbapedia also has an article about Tweaking.
Through the use of the bicycle, a player takes advantage of how map data is loaded within Pokémon Diamond and Pearl from a successful attempt of forcing the game to reload map data incorrectly.

In Pokémon Diamond and Pearl, the term 'Tweaking' or 'Holepunching' refers to when the game unsuccesfully loads nearby map data which was previously not present on the screen. Within these games maps are broken up into 32x32 squares which are only visible at any one time. When the player moves out of this region an extra nine squares are loaded at the edge of the screen in order to replace the older tiles. However, when the player is moving at relatively higher speeds in between the points at which extra map data is loaded the game will occassionally fail to reload the map data effectively.

This glitch is very similar to a much older glitch which only existed in older builds of the Japanese versions of Pokémon Diamond and Pearl which was known by many fans as the "Darkrai and Shiemi glitch", as a slight bug in the map of Elite Four Aaron's room allowed the player to surf through the door and run across the blank space that occupy other in-game maps. As a result of this players could not only get to nearby areas such as the Hall of Fame room but with meticulous planning they could also access Fullmoon Island and Flower Paradise in order to catch Darkrai and Shaymin (whose name was at that time not officially translated into English and was simply romanised by fans as 'Shiemi'). However, after the release of later versions of Pokémon Diamond and Pearl Nintendo had fixed the Surf through Elite Four door Glitch after many players complained about becoming stuck in "the void." After a fairly long time period of disappointment from some fans of the Surf through Elite Four door Glitch a few months after English versions of Pokémon Diamond and Pearl the Tweaking glitch was first discovered in areas such as Jubilife City and the route below Solaocean Town for when the player uses the bicycle in a small square along the middle of the map where the tiles at the bottom of the screen are reloaded.

When the Tweaking glitch has been performed successfully the player will hopefully be able to travel through a black or white "void" so that he or she can access a desirable location, however sometimes the player cannot access the void and occassionally the game may freeze. If the player wants to return the map data to normal however, they can either cross an area outside of the 'void, use the moves Fly, Dig or Teleport if possible, enter a building or other warp, use the underground kit and move back to the main map interface, view another in-game interface such as the Pokémon screen presuming that the player is outside of the void or simply turn the game off, presuming that the player has not saved the game after performing this glitch.

The Tweaking Glitch is harder to perform in the newer Generation IV games, namely Pokémon Platinum and Pokémon Heartgold and Soulsilver as Nintendo have decided to use a new engine for how the game manages map data. It is also notable that currently Arceus cannot be safely obtained through the use of both the Tweaking Glitch and the Surf through Elite Four door Glitch because the location where Arceus exists occupies an entirely different layer on the main map interface, however segments of the Hall of Origin have been found through the use of this glitch.

Requirements for the Tweaking Glitch (for a player who wants to catch Darkrai and Shaymin)

  1. A bicycle in order to activate 'the void'
  2. An explorer kit in order to reload map data.
  3. A Pokétch (highly reccommended)
  4. A berry Pokétch in order to restore any glitched graphics (reccommended)
  5. A Step Counter application for the Pokétch (highly reccommended)
  6. Any Pokémon with a move such as Fly, Dig or Teleport incase the player becomes trapped (reccommended)
