The Super Mario Galaxy community crossed a technical milestone long treated as a horizon: the Wii game's code is now 100% decompiled. The announcement came from Super Hackio and Luma's Workshop, the team behind Petari. In parallel, the same group started Astrocore, a native PC port that the team says is written entirely by humans.
Decompilation is not copying Nintendo's binary. It reconstructs, in C++, a readable equivalent of the original program from the executable. That lets the game be studied, modded and, in Astrocore's case, recompiled to run natively on a PC instead of only through an emulator. Assets remain Nintendo's property. Players must supply files from their own copy.
What changed
Super Hackio confirmed the 100% mark in a video published on September 27, 2026 and pointed to the Astrocore site. The Petari team on the SMGCommunity GitHub org is expected to clean up and then focus on Super Mario Galaxy 2, the Garigari project.
The codebase is far larger than Super Mario 64, decompiled in 2019. Community reports put Galaxy at about seven times more code. The team stresses there was no vibe coding and no automated generation of the port.
What Astrocore promises
A decompilation-based port opens the door to an unlocked frame rate, higher resolution and mods that can touch game logic. Wider co-op and new levels are community speculation, not an official roadmap.
The project site states that Mario, Luigi and related images belong to Nintendo and that there is no company endorsement. Nintendo has not issued a public statement on Astrocore so far.
