About snes-rom-image-python
snes-rom-image-python is a Python library designed to handle Super NES cartridge images. It provides functionality to inspect what a dumping device added to a file, interpret header declarations, and modify images by clearing coprocessor declarations or recomputing checksums. The library is built to adhere to Nintendo's SNES Development Manual and has been validated against a library of 7,330 cartridges. It consists of five primary modules: `dump` for analyzing file structure and copier stubs, `identity` for file identification via digests, `rewrite` for header manipulation, `manifest` for identifying file mismatches, and `copier` for managing backup unit or flash cart formats. The package requires Python 3.12 or newer and includes a `doctor.py` script to verify the environment and checkout integrity. It is intended for use as a library and does not provide a standalone CLI for general end-user tasks, though it includes internal testing and diagnostic tools. It is uncertain if the library is intended for use by AI agents, though its modular, programmatic interface is designed for automated analysis of ROM data.
