# Mickey Saves the Day 3D Adventure: matching decompilation and native ports

> Mickey Saves the Day 3D Adventure reconstructs the game's C/C++ source and builds ports for Apple Silicon macOS and WebAssembly. The author reports checking functions against Visual C++ 5.0 or 6.0 output byte by byte; the ports read game data from a user-supplied German or British English CD image.
