# atolm: a matching decompilation of Panzer Dragoon Saga

> atolm reconstructs selected Panzer Dragoon Saga program segments as C source and compares compiled bytes with originals extracted from the user's USA Disc 1. Its research identifies the Hitachi SHC compiler family and documents differences between the available Release31 compiler and the likely original build. The author reports byte-matched units while tracking attempted and unattempted code separately.

## Requirements & limits

- **Prerequisites:** A legally obtained US Panzer Dragoon Saga disc is required for extraction and full comparison.
- **Prerequisites:** Building requires Linux with Docker, GNU make, Python 3 with PyYAML, and the Hitachi SHC toolchain fetched by the project's setup process.
- **Limits:** The available SHC Release31 compiler may leave some functions unmatched because of version differences.
- **License:** No licence file in the repository.
