Super Mario Galaxy 2: selected gravity behavior and format reconstruction

Super Mario Galaxy 2: selected gravity behavior and format reconstruction implements host-side C++ versions of selected CubeGravity, PlanetGravity and PointGravity operations. It provides bounds-checked readers for Yaz0, RARC, U8, BCSV/JMap, Wii FST and selected J3D metadata, with synthetic-input tests.

How evidence classes are assigned

Requirements & limits

Prerequisites: CMake 3.20 or later and a C++20-capable compiler are required.
Prerequisites: The optional game-data test and asset scanner require a user-supplied extracted DATA directory.
Limits: The shared source lacks the complete runtime; J3D support is partial, and the separate macOS preview has a fresh-launch error.
License: No licence file in the repository for the original native modules, tests and scripts; runtime patches carry their upstream notices.
