  First public release: a Rust workspace of parsers, decoders, and a dm2
  command-line tool for the assets of Dungeon Master II: The Legend of
  Skullkeep, covering the PC (DOS), Macintosh, Amiga, and Sega CD editions in
  both little- and big-endian byte orders.

  Added

  • dm2 CLI — inspect, extract, convert, repack, render, and edit game
    assets:
    • info — print format metadata for a single asset file.
    • extract — unpack graphics.dat / dungeon.dat into a directory, with
      indexed-PNG transparency detection, font-sheet spacing control,
      console-family lighting (--style / --light), per-language text
      filtering, and additive type filters (--sfx, --music, --palette,
      --font, …).
    • dump — convert a recognised file to JSON.
    • convert — transcode music between formats (HMP↔MIDI, …) and savegames
      between DOS and Mac layouts.
    • repack — reassemble an original install into a target engine's expected
      layout.
    • render — render music to 16-bit audio: Mac via the SoundMusicSys synth
      (22254 Hz), DOS via OPL2/OPL3 (49716 Hz), Amiga via a Paula-faithful
      ProTracker replayer (44100 Hz). WAV to a file, raw s16le PCM to stdout.
    • verify — round-trip parse → emit → byte-compare to prove writer fidelity.
    • save — read and edit savegames.
  • dm2-graphics — parser and writer for graphics.dat (format 3/4/5, LE
    and BE), including image, palette, font, text, and sound-effect payloads.
  • dm2-dungeon — parser and writer for dungeon.dat (LE and BE variants).
  • dm2-saves — parser and writer for savegame files (SkSave.dat,
    sksave.bak), across DOS and Mac variants.
  • dm2-music — decoders for DM2 music and audio: HMI/HMP (DOS), Amiga MOD,
    and the Macintosh classic resource fork ('Midi' SMF, 'snd ' Sound Manager
    samples, plus AppleDouble v2 / MacBinary II unwrappers).
  • mod-audio — ProTracker (Amiga MOD) rendering with Paula-faithful hard
    panning.
  • dm2-ftl — parser for the FTL 68k module container used by the Sega CD
    and Amiga ports (and the DM/CSB console ports), including the zero-run
    HUNK_DATA and nibble-stream HUNK_CODE decompressors and all four
    container checksums.
  • dm2-wav — WAV writing helpers for the audio formats the game shipped.
  • dm2-binrw — workspace-internal binrw glue: trait-bounded
    parse / write / to-bytes helpers shared by the binary parsers.
  • dm2-test-fixtures — workspace-internal test helpers that resolve paths
    against fixtures/ and skip silently when a fixture is absent.
  • Per-crate examples/ demonstrating minimal use of each library crate.
  • Engineering hygiene: CI, cargo-deny supply-chain checks, Kaitai Struct
    format specs, rustdoc pages, and fuzz targets.

  Notes

  • The reusable synth crates opl-audio and sms-audio were split out of this
    workspace and are published separately on crates.io; dm2-tools consumes
    them as external dependencies.
