Overview
- In late September 2026, Luma's Workshop announced it has fully decompiled Super Mario Galaxy and showed a running fan build called AstroCore.
- The developers said they "anticipate a release soon" and are directing interested users to the project's Discord for build previews and updates, while making clear the port is unofficial.
- Decompilation reverses a game's compiled code back into a form that can be rebuilt for new platforms, which lets fan ports run natively on PC and add higher frame rates, widescreen support, custom controls, and mods.
- The project emphasizes human-written code and plans to move the decompilation team to Super Mario Galaxy 2 after cleanup work, but it operates in a legal gray area given Nintendo's history of protecting its intellectual property.
- If released, the port could change how players access the game by removing the need to emulate Wii hardware, but it may also face takedown risks and distribution limits that could keep it unofficial and community-hosted.
