Which console received the first Western release of Pokémon Stadium?

The first Western release of Pokémon Stadium was on the Nintendo 64.

Pokémon Stadium is a 3D strategy and battle game developed and published by Nintendo. It uses the Nintendo 64’s hardware to present turn-based Pokémon battles in fully rendered arenas, featuring announcer commentary, stadium tournaments, Gym Leader challenges, and minigames.

The Japanese series history is slightly more complicated. A Japan-only game called Pocket Monsters Stadium appeared in 1998, while the Western Pokémon Stadium release followed in 2000. The international game was also released in Japan under a title corresponding to Pokémon Stadium 2, reflecting its position in that market’s naming sequence.

A bundled Transfer Pak allowed players to connect Pokémon Red, Blue, and Yellow cartridges to the Nintendo 64 game. This made it possible to use trained Pokémon from the Game Boy games in Stadium battles. The game supported all 151 original species, unlike the earlier Japanese release’s smaller selection.
