Editing Data resetting

'''Data resetting''' is a [[glitch]] in [[Microsoft's version of Chip's Challenge]] allowing data stored on a virtual 32nd row of the [[grid]] to affect gameplay. It is commonly an element of [[insane level]]s. Data resetting is not emulated by [[Tile World]], and does not exist in [[Lynx]] or in [[Chip's Challenge 2]].

Each coordinate [x, 32] corresponds to a byte of information. A byte can store any number from 0 to 255 and is adequate for a piece of information such as the x-coordinate of Chip.

However, some data, such as the time limit of a level, require two bytes of information, as two bytes can store any number from 0 to 65535. These bigger pieces of data will take up two consecutive squares, [x, 32] and [x + 1, 32] where x is an even number. In this case, [x, 32] stores the low-order byte of the data, and [x + 1, 32] stores the high-order byte of the data. Resetting [x, 32] will only reset the low-order byte, and resetting [x + 1, 32] will only reset the high-order byte.

* '''[0, 32]''' and '''[1, 32]''' store the level number.

* '''[2, 32]''' and '''[3, 32]''' store the number of levels in the set.

* '''[4, 32]''' and '''[5, 32]''' store the time limit of the level.

* '''[6, 32]''' and '''[7, 32]''' store the number of chips required in the level.

* '''[8, 32]''' and '''[10, 32]''' store the x- and y-coordinates of [[Chip]].

* '''[12, 32]''' stores Chip's sliding state: 1 if he is on any [[sliding tile]] and 0 if he is not.

* '''[14, 32]''' stores the current keystroke's buffer state: 1 if a keystroke is in buffer (more than one keystroke has been attempted within one turn) and 0 if it is not.

* '''[18, 32]''' and '''[20, 32]''' store the x- and y-directions of the keystroke. Note that one of these must always be zero.

* '''[22, 32]''' stores Chip's [[Death message|autopsy report]]:

* '''[24, 32]''' and '''[26, 32]''' store Chip's x- and y-directions when he is sliding. One of these is always zero, and both are zero when Chip is not sliding.

* '''[28, 32]''' stores the amount of monsters in the monster list before the player starts playing the level.

* '''[30, 32]''' and '''[31, 32]''' store the coordinates of the initial position of the first monster in the [[monster list]].

In order to reset data stored in a square [x, 32]:

* The buried north clone block will move north, wrapping around the map, and appear at [x, 31] as a normal block.

* The data stored at [x, 32] will be reset to 0.

* The buried tile in the lower layer of [x, 0] will be replaced with a tile with the index equal to the data formerly occupying [x, 32]. This index is written in the infobox on the respective tile's page.

Resetting the data at [0, 32] will cause Chip's Challenge to read the current level as level the first multiple of 256 before the actual level number. If the actual level number is less than 256, then the current level will be read as 0. In this situation, no [[Chip's Challenge scoring|level bonus]] is awarded on completion, the next level is read as level 1 on completion or moving forwards, and attempting to restart or going back a level will cause the [[Termination Glitch]], as Chip's Challenge cannot load a level 0 or -1. This type of level is known as a [[warp station]], and was developed as a substitute for a [[dummy level]].

Resetting [8, 32] will make Chip warp to the left side of the screen, and with [10, 32] he will warp to the top of the screen. Resetting [12, 32] will make Chip stop sliding, even on ice, though some other [[object]] will have to trigger the [[red button]]. Resetting [22, 32] will make Chip invincible for the next turn, allowing him to pass through [[destructive obstacle]]s.

The result of such behavior also includes changing the tile itself, to create items out of nowhere. If Chip's x-coordinate was 21 and the data at [8, 32] is reset, an [[exit]] will be buried at [8, 0]. Note that most data resets are limited, as they only reach up to one. The level number and Chip's coordinates are generally the most useful.

A peculiar effect occurs when performing data resetting in level 49 of a level set. Recall that 49 is the index of a clone machine. Therefore [0, 32], which stores the current level's number, will store (effectively) a clone machine. Performing the steps to reset [0, 32] will in fact not reset the level number as it does in any other level. It will instead clone the block to [0, 31] as if there were a clone machine ''underneath'' the buried block at [0, 0].

The same effect can be achieved if the level set has exactly 49 levels. In this case, [2, 32] will hold the number 49 for any level in the level set.
