Map distortion glitch item

Map distortion glitch items are glitch items found in Pokémon Red and Blue.

These glitch items are capable of causing a map distortion effect after they are viewed in the player's inventory, provided that the player is both in a grassy area and has a player name that is at least four characters long.

These include many of the glitch items with IDs between 0x74 and 0xC3, especially item 0x87, known as ####PkMnぉゥ# #ゥ #ゥC ##.

The cause of the corruption is likely due to a name length overflow caused by the game attempting to print grass tiles in the item's name as control characters, which both have the index number 0x52.
