This article lists GameShark codes for the main handheld Pokémon games up to Generation II. They also work for Xploder GB.
To find identifiers (the value for '??' or 'xx') for glitch Pokémon, items, moves or letters, use the Big List. Users are welcome to put these in the code archives too.
Please report any broken codes on the respective article's talk page, or on the forums.
Codes from Pokémon games later than Generation II are currently not allowed.
