Play Pokemon Stadium Advanced (Beta 1.1) Online

Pokemon Stadium Advanced (Beta 1.1) is an unreleased Game Boy Advance title, a portable adaptation of the Nintendo 64 battling sim. It was developed by Nintendo, though it never saw a commercial release, existing only as a prototype from that transitional period when developers were pushing the GBA's hardware to handle more complex, console-like experiences.

You don't control a trainer directly; instead, you select from preset teams of Pokémon and manage their moves in turn-based battles. The main objective is to defeat your opponent's team through strategic type matchups and clever use of abilities. Signature mechanics include the direct port of the N64 battle animations, which are noticeably compressed but retain their charm, and the implementation of all standard status conditions and move effects from the core series. The pacing is brisk, focused purely on combat without the exploration of a mainline RPG, and the difficulty can spike depending on the pre-built team matchups. It feels like playing a condensed, portable version of a friend's couch multiplayer session.
