Rusted Iron Ring

Low-level library for exploring From Software games files.

This project is mainly to play with the Rust language, Nom parser, FFI, etc; if you need an actually used and tested library, see SoulsFormats (C#) or soulstruct (Python). The main target has been Dark Souls 1 PTDE, but checkout the features section below.

Usage

The project contains 2 artefacts:

• ironring, a library with all the projects features implemented.
• rir, an executable to use main lib features from the CLI.

    bhds        Extracts all BHD/BDT content (alphabetically) in a folder
    bhf         Extracts BHF/BDT contents
    bnd         Extracts BND contents
    dat         Extracts King's Field IV DAT contents
    dat-pack    Packs files in a King's Field IV DAT
    dcx         Extracts and decompress DCX data
    hash        Calculates hash for a string
    help        Prints this message or the help of the given subcommand(s)

Features

Format support

Type	Games	Features
BHD5/BDT	DS1	Load, extract
DCX	DS1	Load, extract, repack (untested)
BND3	DS1	Load, extract
BHF3	DS1	Load, extract
DAT	KF4	Load, extract, repack
PARAMDEF	DS1	Pretty-print
PARAM	DS1	Pretty-print, optionally with a PARAMDEF

Formats typically found within DCX files can usually be decompressed on the fly.

Repacking is mostly not supported, maybe one day. It is not that useful when using UDSFM and Yabber, but if you really need it you can check out SiegLib.

Misc

• Encrypted archive name hasher.
• There is a demo Python binding for some name_hashes features in the bindings/python dir, that uses PyO3 and thus requires nightly rustc to build.
• There are a few scripts useful for some testing/modding tasks.
