To celebrate the Wii Virtual Console re-release, the Japanese Yahoo! Kids Pokémon page streamed all of the episodes in which Todd Snap appeared from December 14, 2007 to January 14, 2008.
Pokemon Snap originally started development as a Nintendo 64DD game, but was switched to the Nintendo 64 as a cartridge game because of the 64DD's poor sales.
Several of the Pokémon in the game retained their Japanese voices. Because the English voice clips were drawn from the anime, and those Pokémon had not yet appeared in the English dub, voice actors had not yet been chosen for them.
Originally, the game was developed as a non-Pokémon game in which the player simply took photos, with no Pokémon at all. When the motivation for the game became unclear, it was transformed into a Pokémon game.
