Pyxel - RetroBIOS¶
Technical notes
Retro game engine for Python by Takashi Kitao. The engine is a Python package with a Rust-based extension (crates/pyxel-core, built via maturin). Pyxel programs are either .py scripts that import pyxel or self-contained .pyxapp bundles (zip archives containing a startup script plus assets).
There is no external BIOS, firmware, or retail data to collect. Everything the engine needs ships inside the Python wheel: python/pyxel/: Python API, fonts, shader, examples crates/pyxel-core/: Rust engine (compiled as pyxel_extension) crates/pyxel-platform/: SDL2 wrapper crates/pyxel-wrapper/: Python to Rust glue (PyO3)
Batocera's packaging (package/batocera/emulators/python-pyxel/python-pyxel.mk) installs the wheel into site-packages, drops the examples, and provides a pyxel.keys evmapy layout. The content run by Pyxel is the user's .pyxapp or .py file, which plays the role of a cartridge; those are user content, not pack contents.
The engine refuses nothing on startup; a bare pyxel init plus a user
script is enough to run.
No BIOS or firmware files required. Generated on 2026-10-10T11:26:02Z
