Super Mario Galaxy fully decompiled: a native PC port in the works
By Tgames · · 1 min read
2026 update: the decompilation is already behind an unexpected port, on the Game Boy Advance; read on in our news story Super Mario Galaxy ported to the Game Boy Advance, gravity included.
This is a first for the Wii. The collective SMGCommunity completed, in late September 2026, the 100% decompilation of Super Mario Galaxy, at the end of the Petari project: the game's machine code has been turned back into readable C++ source code, which when recompiled gives back the original game exactly.
Why it matters
A decompilation is not an emulation. Instead of simulating the Wii, you have the game's own code, which opens the door to native ports: the game then runs directly on the target machine, without the emulation layer and without its flaws.
AstroCore, the PC port
Right after that, the group Luma's Workshop announced AstroCore, an unofficial native PC port: 60 frames per second, higher resolutions, extended draw distance, support for mods and texture packs. The developers insist on one point, in an age of automatic tools: the work is “100% coded by humans”. No release date has been announced, the team speaks of a release “soon”, and is already moving on to Super Mario Galaxy 2.
Worth keeping in mind
A port of this kind does not contain the game's assets: you will have to supply the files taken from your own disc, as with the ports of Zelda: Ocarina of Time or of Mario 64 before it. That is what sets these projects, which survive, apart from those that distribute the complete game and vanish under the complaints.
