# Skies of Arcadia Legends: matching GameCube decompilation

> The Skies of Arcadia Legends project reconstructs C source for the USA GameCube release and builds a byte-identical main.dol from a user-provided disc image. It tracks function-level matches, uses objdiff for comparison and documents compiler behavior affecting Sega's Ninja graphics library; some matched library code is imported with attribution.

## Requirements & limits

- **Prerequisites:** An existing copy of the GEAE8P Rev 0 USA game disc image is required.
- **Prerequisites:** Python and Ninja are required for the build; Linux and macOS builds also use wibo.
- **Limits:** The author reports 74.75% of code bytes matched with stock compilers; the work remains in progress.
- **License:** CC0-1.0 license for the repository's own work; imported library source retains documented upstream provenance.
