Pokémon Stadium (Japanese)

The first game of the Stadium series, called Pokémon Stadium (Pocket Monster Stadium), was released in Japan in 1998. This version featured only 42 Pokémon instead of all of the 151 Generation I Pokemon, and was not released outside of Japan. This game was originally intended for the Nintendo 64DD format, but as the Nintendo 64DD was a commercial failure, Pokémon Stadium transferred to Cartridge format. There was also a Pocket Monsters Stadium Expansion Disk, a proposed add-on for the Nintendo 64DD, but was never unreleased. The 42 Pokémon included in this version were: Venusaur, Charizard, Blastoise, Beedrill, Fearow, Pikachu, Nidoqueen, Nidoking, Dugtrio, Primeape, Arcanine, Alakazam, Machamp, Golem, Magneton, Cloyster, Gengar, Onix, Hypno, Electrode, Exeggutor, Chansey, Kangaskhan, Starmie, Scyther, Jynx, Pinsir, Tauros, Gyarados, Lapras, Ditto, Vaporeon, Jolteon, Flareon, Aerodactyl, Snorlax, Articuno, Zapdos, Moltres, Dragonite, Mewtwo, and Mew.
