Pokémon Stadium 2

Pokémon Stadium 2, known in Japan as Pokémon Stadium Gold & Silver, is a strategy video game developed and published by Nintendo for the Nintendo 64. It is the third game in the Pokémon Stadium series, following prior releases Pocket Monsters Stadium and Pokémon Stadium. It features all 251 Pokémon from the first and second generations of the franchise, and allows for players to battle either with other players or against computer-controlled opponents. Like its predecessor, Pokémon Stadium 2 is compatible with the Transfer Pak accessory, allowing players to use Pokémon trained in the three original Game Boy Pokémon games (Pokémon Red, Blue, and Yellow) and the three Game Boy Color games (Pokémon Gold, Silver, and Crystal).
