Fans working through Luma’s Workshop have previewed AstroCore, an unofficial native port of SUPER MARIO GALAXY for computers, but the project remains in development with no public download available.
“Fundamentally, I think a Mario game is the type of game that’s really not about completing the game, but rather about having fun just playing,” said original SUPER MARIO GALAXY director Yoshiaki Koizumi in Nintendo’s 2007 Iwata Asks interview about the Wii game, not in a response to the new fan project. His historical comments do not suggest Nintendo supports AstroCore.
The distinction matters as headlines introduce the project to readers who might assume a finished PC version has arrived. ScreenRant’s September 29 report describes the fan effort as an upcoming port and says no specific release date has been announced. Nintendo originally released the game for Wii in 2007.
The project’s own website makes its present status clear: development continues, and the public cannot yet download it. That is different from the team finishing its decompilation work, which reconstructs the original game’s code into a form developers can work with.
According to Luma’s Workshop’s FAQ, AstroCore uses the completed decompilation rather than an automated recompilation process. The developers describe their porting work as manually reworking that foundation to create software for computers.

The planned platform list extends beyond Windows PCs to macOS, Linux, SteamOS and Android, using a compatibility layer called Aurora. Those are the team’s stated targets, not a list of platforms on which a public release has already been tested.
The developers also aim to support a wide range of controllers, including the original Wii Remote and Nunchuk, with customizable button mapping. They list texture-pack and modification support, while reserving more information about those features and possible online multiplayer for later announcements.
SUPER MARIO GALAXY 2 remains a future goal rather than a completed second port. The FAQ says its decompilation effort will begin soon and that AstroCore will add support once that work has progressed far enough, while warning that the project may take time.
Luma’s Workshop also addresses questions about generative AI. It says the reverse-engineering team did not use AI, that humans wrote the actual decompilation code and that AstroCore’s programming will be AI-free; those statements describe the developers’ account of their work.
The website states that AstroCore does not include unmodified game assets and expressly disclaims affiliation with or endorsement by Nintendo. Neither that statement nor the project’s technical approach establishes permission from Nintendo, and this report makes no legal judgment about the project.
Families do not need to wait for the fan project to revisit these adventures on current Nintendo hardware. Nintendo released SUPER MARIO GALAXY and SUPER MARIO GALAXY 2 for Nintendo Switch on October 2, 2025, with enhanced resolution, adapted controls and additional content, plus further visual enhancements on Nintendo Switch 2.
