The Luma's Workshop modding community has successfully completed a 100% decompilation of Super Mario Galaxy, transitioning the game to a native PC port titled Astrocore. This community-led initiative was realized through human coding efforts rather than automated translation tools.
Why it matters
The achievement enables native PC playback of the game by allowing the original source code to run on modern hardware without traditional emulation. This development marks a shift in game preservation, as the community now intends to begin similar work on Super Mario Galaxy 2.
The decompilation project reached 100% completion, successfully converting the original game code into a human-readable format. This effort ensures the code is fully native for PC execution, diverging from prior approaches that relied on hardware emulation.
The players
Luma's Workshop
A community of software modders focused on reverse-engineering and porting console games to PC.
The details
Decompilation is the process of reversing machine-readable binary code back into human-readable source code. By human-coding every line, the developers ensured that the game logic could be recompiled for native PC environments rather than simulating the original console. The project, dubbed Astrocore, aims to modernize how older titles are accessed outside of their original hardware specifications.
Timeline
September 28, 2026: The team finalized the 100% decompilation of the game code.
The Tech Race
The Astrocore project follows the precedent set by the 2020 decompilation of Super Mario 64 by moving from emulation to native source-code ports. This milestone establishes a new path for high-fidelity game preservation where enthusiasts seek to bypass hardware-level constraints through direct code translation.
Users can expect native PC performance once the team releases the finalized port, offering higher compatibility than traditional console emulators. As the project is currently in the cleanup phase, the community is awaiting further instructions on how to install and configure the port on standard Windows systems.
The takeaway
This successful decompilation provides a roadmap for the community to begin work on Super Mario Galaxy 2 after finishing the current project cleanup. Interested users should monitor Luma's Workshop for future announcements regarding the final release build.
