Super Smash Bros. Melee just crossed the finish line most preservation projects only dream about: 100% decompiled into C code after six-plus years, producing a binary that matches the original GameCube main.dol byte-for-byte. The doldecomp/melee GitHub repo and decomp.dev tracker confirm the milestone hit recently, with the US v1.02 version (SHA-1 08e0bf20134dfcb260699671004527b2d6bb1a45) now fully rebuilt from source. OpenAI's Astra model gets credited for helping close the final gaps on a project that had already clawed its way past 95% in the months prior.

This isn't a playable PC port or an official re-release—it's source code you compile back into the exact same 3.88MB executable, using assets you already own from a legitimate disc. The payoff sits in the details: modders and researchers now have human-readable C instead of raw assembly, which is the real unlock for future tools, ports, and deep engine work. Other GameCube decomp successes like Twilight Princess and Pikmin show the pattern—once the code is open, the scene moves fast.

Nintendo will pretend this changes nothing. The competitive community that kept Melee alive for 25 years just gained the technical foundation to keep it running long after the last working GameCube dies. Six years of stubborn reverse engineering beats another round of corporate nostalgia bait.
