Apple Silicon wheels for stable-retro without bundled ROM payloads

stable-retro-apple-silicon

stable-retro-apple-silicon is an Apple Silicon focused packaging fork of stable-retro.

This fork is aimed at a simple outcome:

• publishable macOS arm64 wheels
• no bundled ROM payloads in public artifacts
• verified support for Game Boy, NES, SNES, and Sega Master System on Apple Silicon

What This Package Includes

• the stable_retro Python package
• the retro compatibility shim
• Apple Silicon compatible cores for:
  • Game Boy (gambatte)
  • NES (fceumm)
  • SNES (snes9x)
  • Sega Master System (genesis_plus_gx)
• integration metadata, scenarios, and rom.sha hash files

What This Package Does Not Include

Public wheels built from this repo do not ship copyrighted ROM payloads.

In particular, files named rom.* are excluded from wheels and sdists, except for rom.sha, which is retained as metadata for the importer.

Installation

pip install stable-retro-apple-silicon

Supported runtime target:

• macOS 11 or newer
• Apple Silicon (arm64)
• Python 3.9 through 3.12 for published wheels

Importing Your Own ROMs

After installation, import ROMs you already own into the package data layout:

python -m stable_retro.import /path/to/your/roms

Once imported, you can create environments normally:

import stable_retro as retro

env = retro.make("SuperMarioWorld-Snes-v0", render_mode="rgb_array")
obs, info = env.reset()

Verified Platforms In This Fork

The current Apple Silicon release path is verified for:

• Alleyway-GameBoy-v0
• SuperMarioBros-Nes-v0
• SuperMarioWorld-Snes-v0
• SonicTheHedgehog-Sms-v0

These map to the four public cores shipped by this package.

Building Wheels

Local wheel builds use the Apple Silicon safe defaults defined in this fork:

• deployment target: macOS 11.0
• curated core set: gb;nes;snes;genesis
• public package core set: gambatte,fceumm,snes9x,genesis_plus_gx

Typical local build:

python -m pip install --upgrade build
python -m build --wheel

Publishing

This repo is set up to publish wheel artifacts from GitHub Actions.

The intended release flow is:

1. Update stable_retro/VERSION.txt
2. Push to main
3. Create a GitHub release tag like v0.9.10
4. Let the release workflow build and upload the wheel to PyPI

See the repo root PUBLISHING.md for the release checklist.

Notes

• render_mode="human" still requires a real display session.
• render_mode="rgb_array" is the reliable mode for headless validation.
• This fork does not currently promise support for every upstream stable-retro platform on Apple Silicon.
