About this project
C decompilation of the arcade program and sound driver, with a playable SDL2 reference port. It is the foundation for the separately distributed segasonic-port.

Compatibility
The SDL2 port is documented as built/played on Windows. Other desktop builds and Switch/ARM handheld work are not treated as verified just because they appear in the roadmap.

Known limitations
v1.0.1 fixes extraction output. Re-extraction overwrites edited assets, so back them up. Author-reported reference comparisons are not an AllRecomps gameplay test or a measured completion percentage.
