Unused Graphics

Butterfrees Banner

Freeeeeee!

An animation of two Butterfrees holding a banner, found within the main menu graphics. It may have been used to display the names of the locations at one point. In the final game, each location name is on a cloud.

Looks like Metapod wanted to be a Pokémon master too.

Regional Differences

Careful, you'll lose an eye.
This page or section needs more images.
There's a whole lotta words here, but not enough pictures. Please fix this.
  • The NTSC and PAL versions of the game play a slightly different theme for the opening cinematic, the latter including more instruments.
NTSC PAL
  • As with Pokémon Snap, the Pokémon voices in the Kids Club minigames were changed to match the English dub of the anime.
  • American versions of the game had a Gallery feature, which allows players to take pictures of their Pokémon. Strangely, this feature is absent in PAL builds.
  • Since the original Pokémon Stadium was never released outside of Japan, a method to get Surfing Pikachu was added to international versions.
  • International versions replaced the three Nintendo Cups with a Poké Cup from Pokémon Yellow's Colosseum 2.
  • Nidoqueen's "stance" when sent out was altered in the international versions.
  • The number of teams that could be registered was decreased from 12 to 10.
  • Upon launching, Pikachu's voice is heard in international versions. In Japanese version, people's voices were heard instead.
