Pokémon Stadium Finally Runs Natively on PC Thanks to a New Recomp

After Super Mario 64, The Legend of Zelda: Ocarina of Time and Paper Mario, Pokémon Stadium is now joining the growing list of Nintendo 64 games ported natively to PC using the so-called "recomp" technique. Named SS Anne, the project is developed by programmer Matt Stanley (aka mstan) and relies on the open source N64Recomp framework, which converts the original cartridge's machine code into native code that a modern PC processor can run directly, without any emulation layer.

The current build, numbered v0.4.2-beta, keeps the most beloved features of the original game: the GB Tower and full Transfer Pak support are both functional, letting players connect a real Game Boy cartridge to a Transfer Pak hooked up to the PC to transfer a Pokémon team. The project also brings sharper models and several fixes compared to the original N64 release.

Claude, the contributor splitting the recomp community

What's drawing particular attention is that mstan has said he used Anthropic's AI assistant Claude to help with parts of the development, going as far as listing it as a contributor to the project on GitHub. This is still a rare practice in the famously demanding world of decompilations and recomps, where several developers worry that heavy reliance on AI could produce code that is "more janky and unpredictable", still requiring careful human review before release.

To try it out, you'll need a legal copy of the US Pokémon Stadium ROM (MD5 hash ed1378bc12115f71209a77844965ba50): the project contains no copyrighted files of its own. The GitHub releases page offers a ready-to-use Windows executable, while the main repository details the step-by-step setup process in its "Quick start" section.
