  Added

  • C bundles — tagged releases now attach dm2-ffi-<ver>-x86_64-linux-gnu
    and -x86_64-windows-gnu archives, each with the cbindgen header, the shared
    library, the crate README carrying the Dm2Buffer ownership contract, and
    both licenses. The Linux one is built in the manylinux image, so it needs
    only glibc 2.28. The 30-40 MB static archive is left out: it would grow the
    compressed bundle elevenfold to duplicate what the shared library provides.

  Changed

  • dm2-wasm — prepared for npm. build-npm.sh builds the package for the
    bundler target and publishes it under the name dm2-tools, matching the
    PyPI distribution; the crate ships copies of the two licenses, which
    wasm-pack bundles, build-npm.sh lists in files so npm actually packs
    them, and CI diffs against the originals; and wasm-opt now optimises for
    size (-Oz). CI gained a wasm32-unknown-unknown check,
    since a host build compiles the #[wasm_bindgen] layer inertly and cannot
    catch a break in it.
  • dm2-wasm — no longer published to crates.io (publish = false, and
    0.2.0 deleted there). The bindings target JavaScript, which reaches them
    through wasm-pack output rather than cargo, and the crates.io copy
    documented nothing: docs.rs builds for x86-64, where every #[wasm_bindgen]
    export is compiled out, so the page listed only WasmError. The crate stays
    in the workspace and is built and tested exactly as before. Its unused
    [workspace.dependencies] entry, which carried a version requirement no
    crate consumed, is dropped.
  • Python bindings — requires-python raised to >=3.11. 3.9 went EOL in
    October 2025 and 3.10 follows in October 2026, so the old >=3.9 floor
    advertised runtimes that no longer get security fixes and that the suite
    could not import anyway. Installing already requires a Rust toolchain to
    build the cdylib, so a distro system Python was never the constraint. The
    test helper now parses the manifests with the stdlib tomllib instead of a
    regex. Adds a classifiers list so a PyPI upload carries version, platform
    and Typing :: Typed trove tags.
  • CI — new python job installs the bindings on a standalone CPython 3.11
    (fetched by a pinned, hash-checked uv) and runs their pytest suite, so the
    declared floor and the hatchling cdylib-bundling hook are both exercised.
    Previously nothing in CI touched bindings/python at all.
  • Python bindings — the wheel is now tagged py3-none-<platform> instead
    of cp3XX-cp3XX-<platform>. Nothing links against the CPython C API, so the
    old tag demanded a separate wheel per interpreter minor for no reason; one
    wheel per platform now installs on every supported Python. The build hook
    also clears its _lib staging directory, which previously let a cross-built
    wheel ship a second, wrong-platform library.
  • Python bindings — packaging metadata filled in: [project.urls],
    keywords, and the two LICENSE-* files, which the wheel previously omitted
    despite declaring License-Expression.
  • Release — tagged builds now attach Python wheels:
    py3-none-manylinux_2_28_x86_64 from a new wheel-linux job in the
    manylinux image (auditwheel relabels the linux_x86_64 tag PyPI rejects),
    and py3-none-win_amd64 cross-built with mingw alongside the CLI. Wheels
    only, no sdist — an sdist of bindings/python cannot build, since the
    cdylib it compiles lives in the cargo workspace above it. macOS and aarch64
    Linux wheels are not built; see docs/development.md.
  • Release — the workflow is now two build jobs feeding a publish job
    through Forgejo's upload-artifact action, instead of one job that built
    and published in sequence. Assets are attached only once every build has
    succeeded, so a failure can no longer leave a published tag missing one;
    SHA256SUMS.txt covers the wheels as well as the CLI archives; and a
    workflow_dispatch run leaves every asset downloadable from the run page.

  Fixed

  • Python bindings — bindings/python/pyproject.toml still declared
    0.1.1, so the 0.2.0 wheel carried pip metadata a version behind the
    cdylib it bundles, and the suite's version assertion (hardcoded to the old
    string) failed against it. The package version now tracks the workspace, and
    the test derives both sides from the manifests instead of pinning a literal.
  • Python bindings — tests/test_roundtrip.py annotated a helper with a
    PEP 604 union but omitted from __future__ import annotations, so importing
    the module raised TypeError on the 3.9 and 3.10 that requires-python
    claims to support. The suite only ever ran on 3.11+.

  Added

  • dm2-wasm — browser bindings exposing the parser crates to JavaScript
    via wasm-bindgen. All parser crates already compile to
    wasm32-unknown-unknown unchanged, so this is a marshalling layer rather
    than a port: a pure fn(&[u8]) -> Result<_, WasmError> core covered by
    native tests, one unified WasmError whose Display is the JS-facing
    message, and #[wasm_bindgen] passthroughs with camelCase names. Saves and
    dungeons get a byte-exact self-contained JSON round-trip plus the lossy
    read views; graphics, music, and FTL are read-only decoders (header summary
    and image→PNG; detect, HMP→SMF, MOD→WAV, snd →WAV; FTL container info and
    round-trip). Byte order is auto-detected inside the crate.
  • dm2-convert — wasm-free crate holding the conversion functions and
    their unified error, extracted out of dm2-wasm (now a re-export plus a
    wasm-bindgen shim). Adds resource-fork listing and extraction.
  • dm2-ffi — C ABI over the parser crates: a stateless
    Dm2Buffer { data, len, error } return convention with a single
    dm2_buffer_free, 16 panic-guarded exports plus dm2_version, and a
    committed cbindgen-generated header guarded by a drift-check test.
  • Python bindings (bindings/python, pip-installable dm2-tools) —
    ctypes over dm2-ffi with a Pythonic dict/bytes API and a Dm2Error
    exception, a hatchling build hook that builds and bundles the dm2-ffi
    cdylib into a platform-tagged wheel, and a pytest suite mirroring the ABI
    round-trip and read proofs.
  • Savegame JSON — dm2 dump now emits savegame JSON in three flavours:
    gameplay-only by default (typed header, SGB, globals, champions, effects,
    and timers, each with a raw escape hatch), --self-contained to embed the
    full bitstream so the JSON reloads without a dungeon.dat / graphics.dat,
    and --full (with --gdat and --dungeon) for a field-driven dump whose
    record_stream is editable. Both self-contained and field-driven dumps
    reconstruct byte-identical originals, gated over all 4 DOS retail slots and
    all 14 Mac retail saves. Reconstruction is hardened against hand-edited or
    untrusted JSON: typed errors instead of panics, and a 16 MiB allocation cap.
  • dm2 dump --format dungeon-lossless — self-contained lossless
    dungeon.dat JSON. DungeonDump carries every typed section as editable
    fields plus the tile-data-block tail as a base64 seed, so reconstruct()
    needs no external files, and parse → JSON → reconstruct is byte-exact over
    every dungeon fixture in both byte orders (including the FM-Towns JP
    off-by-one tail padding). Format, schema, length, and allocation guards
    return typed errors instead of panicking. The lossy skproject dump is
    unchanged.
  • serde Serialize/Deserialize derives across the dm2-saves
RecordStream graph and every owned section type of the dm2-dungeon
    graph, so both are usable as data models outside the CLI.
  • Forgejo issue templates (feature / bug / research) that preset the type/*
    labels and prompt for area and port.

  Changed

  • Documentation: a Releasing runbook in the development guide covering the
    dependency-ordered publish; the "Known DM2 ports" table moved into
    docs/sources/overview.md as a "Platform families" section; the Sega CD
    in-game SFX location documented as resolved (they are cls3=0x02 dtSnd
    records in graphics.dat, missed by the 6-byte DOS/Mac SFX-framing scan).
  • Documentation and source comments no longer reference untracked working
    directories, so a fresh clone has no dangling pointers. The one
    load-bearing tool that lived there, extract_mac_object_masks.py, moved
    into tooling/oracle-compare/.
  • Corrected the documented Mac champion mask: its field bit widths are the
    same as DOS (HP/MP 10-bit, stamina 14-bit, food/water 16-bit, popcount
    1045), not widened/narrowed as previously claimed, and the -2 shift drops
    damagesuffered, not bodyflag. Three stale rows in the DOS mask table
    (0x29, food, water) were fixed alongside.
  • Dependencies updated.

  Removed

  • ROADMAP.md, in favour of issues and milestones on the project forge.
    Per-format and per-port reference material stays in docs/.

  Fixed

  • A corrupt savegame is now reported with the parser's own diagnostic instead
    of a generic "could not identify" / "not a recognised DM2 savegame". The
    savegame family gate (the looks_like_* header fingerprint) is now
    separated from the full parse, so info, verify, dump, raw-extract,
    and the save subcommands surface e.g. "sksave truncated in map_table:
    need 704 bytes, got 14" for a truncated save. Matches the behaviour the
    magic-bearing families (graphics.dat, FTL, Mac resource forks) already
    had.

  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.
