Sm64
This project is a game source code decompilation effort that reconstructs a functional C source code representation of a commercial game from its original binary. It provides a compilation system designed to produce binary ROM files that are bit-for-bit identical to original commercial releases.
The project utilizes a containerized toolchain environment to ensure consistent compilation of legacy game source code across different operating systems. This pipeline transforms the decompiled C source into hardware-compatible binaries for the Nintendo 64.
The workflow encompasses C-based source reconstitution, cross-compiler target mapping for MIPS architecture, and the integration of static assets. Integrity is maintained through binary verification, comparing the hashes of newly built binaries against original ROMs to ensure byte-perfect matching.
