What was done #
Nebula is a native Windows recompiler for Super Mario Galaxy. This fork adds Cloud90 Game Link, allowing TikTok live events to trigger in-game effects like inverted controls, screen modifiers, and enemy spawns.
Nebula is a native Windows recompiler for Super Mario Galaxy that translates PowerPC machine code into C++ for execution on modern hardware. The project utilizes a recompiler, a C++ runtime, and a C# installer. The author reports that the game is playable, though some lighting and bloom effects differ from the original, and performance may vary on weaker hardware. The project documentation credits Anthropic's Claude for writing the recompiler, runtime, installer, tests, and documentation, while noting that the original game logic and physics remain untouched. The Nebula Cloud90 fork introduces integration with the Cloud90 Live platform, enabling streamers to trigger in-game events via TikTok interactions. These events include gameplay modifiers like inverted controls, screen effects, and spawning enemies such as Goombas, Bob-ombs, Boos, and Magikoopas. The implementation uses site hooks within the game's runtime to interface with Cloud90 services. Development of these features is documented in the project's commit history, which frequently credits Claude Opus 5.5 as a co-author. Users must provide their own copy of the USA version of Super Mario Galaxy (RMGE01, revision 0) to build the game modules. Nebula Cloud90 Repository
