retrotool-libsfx
Bundled Optiroc SNES toolchain for the retrotool
build pipeline. One wheel, one install, whole stack.
What's inside
Built from vendored upstream sources (git submodules) during wheel construction:
| Tool | Upstream | Purpose |
|---|---|---|
| libSFX | vendor/libSFX |
65816 asm framework (headers + macros, no binary) |
| SuperFamiconv | vendor/SuperFamiconv |
PNG → tiles / palette / tilemap converter |
| SuperFamicheck | vendor/SuperFamicheck |
SNES header + checksum fixer |
| BRRtools | vendor/BRRtools |
BRR audio encode/decode |
| lz4 | vendor/lz4 |
reference LZ4 compressor |
| cc65 | vendor/cc65 |
ca65/ld65 assembler + linker for libSFX projects |
| make_breakpoints | vendor/make_breakpoints |
ld65 symbols → Mesen breakpoints |
retrotool can drive the whole chain from a project.toml or MBXML file.
Users can pick either ca65 (shipped here) or asar (existing retrotool
asm module) as the assembler, per project.
Installation
pip install retrotool[libsfx] # 0.9.0+
Base retrotool stays pure-python; the toolchain is opt-in via this extra.
Setup (development)
git submodule update --init --recursive
cd packages/retrotool-libsfx
python -m pip install build
python -m build --wheel
On platforms where not every submodule builds cleanly (yet), setup.py skips
missing submodules with a warning rather than failing — useful during the
0.8.x → 0.9.0 staged rollout.
Usage
from retrotool_libsfx import (
superfamiconv_binary, superfamicheck_binary,
ca65_binary, ld65_binary, brr_encoder_binary, lz4_binary,
libsfx_include_dir, libsfx_config_dir,
run_superfamiconv, run_ca65, run_ld65,
ToolNotBundledError,
)
run_superfamiconv(["tiles", "-i", "bg.png", "-d", "bg.tiles", "-B", "4"])
