About

SNESRecomp is a general-purpose static recompiler for the Super Nintendo (Super Famicom). It translates 65816 machine code into C, compiles it into a native executable and links it against a shared SNES hardware runtime that models the PPU, APU, DSP, DMA and cartridge mapping, with an interpreter tier for code that cannot yet be resolved statically. The README calls it a framework rather than a collection of ROMs, and says it is alpha software.

How it differs from the original

Projects built on it are described as supporting true widescreen views, Adaptive View, versioned mod packages, MSU-1 audio, cross-platform builds, launchers and save states. The README lists Super Mario World, The Legend of Zelda: A Link to the Past and Mega Man X as public game projects, each in its own repository.

Getting started

The README says to use only a ROM image obtained legally, as SNESRecomp does not include ROM data. A released command-line tool can generate a project from a ROM, and the generated source is then built with CMake, Ninja and a C compiler. The result is only a starting point, since turning a game into a playable native port still needs game-specific work.

Known issues & limitations

The framework and its game projects are alpha, and maturity varies by game.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game.

Features

Projects can use versioned mod packages with independently toggleable features and typed options.
The framework supports save states in projects built on it.

Licensing & legal

The README states the original code is under the PolyForm Noncommercial License 1.0.0, with third-party components keeping their own licenses.

Additional notes

Generated code: The README says the generated C is derived from the ROM and should not be redistributed without permission.
