The '''Celadon looping map trick''' is a method of obtaining any glitch item (with the exception of [[ItemDex/RB:255|CANCEL/TM55 (hex:FF)]]). It was documented by TheZZAZZGlitch.

The '''Celadon looping map trick''' is a method of obtaining any glitch item (within the exception of [[ItemDexEnglish/RB:255|CANCEL/TM55 (hex:FF)]]). It wasnon-English documentedEuropean by{{RBY}} TheZZAZZGlitch.
(with the exception of [[ItemDex/RGBY:255|CANCEL/TM55 (0xFF)]]).
 
It was documented by TheZZAZZGlitch ([https://youtube.com/watch?v=98_azamLeh4 video]), and it mainly abuses the fact that the [[Phantom City|phantom quadrant]] of Celadon City is particularly easy to navigate, allowing the player to walk freely on a horizontal line covering a wide range of X-coordinates. As the player's X-coordinate represents an item in the player's [[expanded item pack]], this translates to a wide range of items.
==Preparation==
To perform this glitch, one needs :
* To master the [[expanded item pack]] glitch.
* Have at least (one is best) one X Special (or item with an ID greater than 31).
* Have a stack of 255 items.
* Have two other items (labelled here item #1 and #2).
 
The trick does not work as well in the Japanese versions, as the X-coordinate represents a quantity rather than an item in these versions, and the [[Out of bounds Glitch City (Generation I)|glitch city quadrant]], with the Y-coordinate out of bounds, is usually hard to navigate.
 
==Method==
First, obtain an [[Expanded item pack]] through a method such as the [[Dry underflow glitch]].
[[File:Celadon looping map trick spot.png|frame|right|The spot where the Nugget x1 will appear as item 35.]]
The player should arrange their item pack in this way :
 
The player should then go eastmost ofto Celadon City and open their menu at the bottom row of tiles (at the spot pictured). The player should then open their bag, and swap the X Special x1 (oran item with an ID greater than or equal to hex:33)0x33 with a Nugget x1 somewhere downlower in the menu.

When the player receives the item they wish, it should be swapped again with the Nugget x1 (or an item that the player wants to replace). If the player uses Fly or Teleport, they can safely return to a Pokémon Center without getting trapped.

The player can stand at spots in Celadon City further to the left than the picture above to manipulate item 34 (normally the Nugget x1) to values hex:00 and hex:30, swap it to the regular item pack space and then Fly or Teleport away.
The player should then toss or deposit 253 of the first item stack, then swap the first item with the second(using SELECT), twice.
 
The player does not have to use Celadon City for this glitch, and it is possible to use this method to obtain any item with an ID<(map's X boundary-1).
If done correctly, the quantity of the first item will be adjusted to x0, and the player should be able to scroll the cursor beyond the CANCEL entry.
 
==Caution==
The player should go eastmost of Celadon City and open their menu at the bottom row of tiles (at the spot pictured). The player should then open their bag, and swap the X Special x1 (or item with ID greater than or equal to hex:33) with a Nugget x1 somewhere down.
When the menu doesn't respond due to a glitch item name, it is highly recommended that the player presses B (and not A) at a slow pace, because an accidental B press may close the menu, and a single accidental A press if a [[unterminated name glitch item]] is selected may cause the game to freeze with a chance of corrupting the save file.

If the menu stops responding due to the name of a glitch item, tapping B multiple times should enable it again.
*[[Cycling Road height trick]]
 
The player is now able to walk right and left. The Celadon City map will be able to loop multiple times until x=hex:32 or x=hex:FF. Each right step increases the item ID of the slot where the Nugget was. Each left step decreases the item ID.
 
When the player receives the item they wish, it should be swapped again with the Nugget x1 (or an item that the player wants to replace). If the player uses Fly or Teleport, they can safely return to a Pokémon Center without getting trapped.
 
To keep the item but fix the items pack, the player should deposit the obtained item in the PC, then buy / receive three items to fix the item pack.
 
==Caution==
When the menu doesn't respond due to a glitch item name, it is highly recommended that the player presses B (and not A) at a slow pace, because an accidental B press may close the menu, and a single accidental A press may cause the game to freeze with a chance of corrupting the save file.
