GoKawiilUnofficial PC port of Super Mario Galaxy released by developer keepvaibin
A developer known as keepvaibin has released an unofficial, native PC port of Super Mario Galaxy, built with help from Anthropic's Claude AI but containing no Nintendo code or assets. The port runs on Windows 10 and up, needs only 8GB of RAM, supports ultrawide aspect ratios, upscaling and multiple controller types, and requires users to supply their own copy of the original game. It remains a work in progress, with some known bugs including frame drops in certain areas and audio skipping under heavy CPU load.

The release adds to a growing pattern of fan-made PC ports of Nintendo titles, such as past Zelda: Ocarina of Time conversions, which could keep pressure on Nintendo's control over how its games are played outside official hardware. Because the port lacks Nintendo's authorization, it may face takedown action, as has happened with similar unofficial projects in the past. The use of AI assistance in development also points to how such tools are increasingly lowering the barrier for large-scale fan reverse-engineering efforts.
- An unofficial PC port of Super Mario Galaxy from keepvaibin is downloadable now, requiring only a legally owned copy of the original game.
- It runs on modest hardware, achieving 60 FPS at 1440p even on a laptop with integrated graphics.
- The project used Anthropic's Claude AI during development and joins a wider trend of unauthorized PC ports of Nintendo classics.
