Case study

OpenMCM2: a Motocross Madness 2 engine reimplementation

OpenMCM2 reimplements Motocross Madness 2 in Rust for macOS, Windows, and Linux using files from the user's own game copy. It decodes archives, terrain, scenes, models, textures, and other game formats, and reconstructs riding physics and AI from study of the original. The author reports that some physics comparisons still differ.
