In Arceus's description, the book details the Azure Flute event despite that it was never distributed anywhere in the world.
On page 3 (Professor Oak's Trivia), Team Galactic is incorrectly named Team Galaxy, their Japanese name.
On page 43, the Japanese names for the Gym Leaders and the locations they appear in are used instead of the English ones.
On page 65 and 66, under the "cheat codes", the book claims that a Pokémon's catch rate can be affected by yelling "gotcha!" into the Nintendo DS's microphone or by pressing and holding the A button when the thrown Ball is "just above the Pokémon's head". Both of these claims are false.
