With the release of version 3.1 of the GameShark for GameBoy Color, InterAct began including a booklet titled "The Ultimate Pokémon Code Book" with the devices. This booklet contains a compendium of codes for the red/blue/yellow/pinball/TCG games.
It seems a number of the codes which were
first featured in my FAQs managed to make their way onto the GameShark site and
into this booklet. You can tell where these codes first came from since the
code descriptions are variants on my own (rather lousy) wording. A few scans of
such parts of the booklet are shown below.
