# Third-Party Licenses

This file inventories every third-party component JoeyLib depends on,
either at runtime (linked into the produced binaries) or at build /
test time. Components are grouped by role; within each group entries
list the platforms that consume the component, the upstream URL, and
the license.

When upstream license terms change, update the corresponding row here.

---

## Runtime libraries (linked into joeylib output binaries)

These ship as part of, or are linked into, an executable built by
JoeyLib. License compatibility for these matters most.

- **License:** MIT
- **Role:** ProTracker / Amiga MOD replayer + SMIX SFX overlay. Linked
  into AUDIO binaries on the chunky-display platforms.

  by Jesse Blue (NinjaForce). Treated here as free for use; consult
  upstream before commercial redistribution.
- **Role:** Apple IIgs Ensoniq DOC `.NTP` module replayer + SFX
  streamer. Merlin32-assembled into `ntpplayer`, which ships on the disk
  next to each IIgs program and is loaded at run time.

---

## Build-time toolchains (NOT linked, used to produce binaries)

These run on the developer's machine to compile / assemble / link
JoeyLib for each target. They are not redistributed inside the
produced game binaries.

### llvm-mos (clang / llvm-mc / link816 w65816 toolchain)

- **Used on:** Apple IIgs
- **URL:** <https://github.com/llvm-mos/llvm-mos>
- **License:** Apache License 2.0 with LLVM Exceptions (the upstream
  LLVM license).
- **Role:** clang C compiler targeting the 65816, plus llvm-mc for
  assembling hand-written `.s` files and link816 for producing OMF
  S16 executables. Driven by `make/support/iigs/clang-build.sh`; the
  toolchain root is located via the `LLVM816_ROOT` environment
  variable.
- **Installed at:** `toolchains/opt/llvm816/` (installer component `llvm816`)

### Merlin32

- **Used on:** Apple IIgs
- **URL:** <https://brutaldeluxe.fr/products/crossdevtools/merlin/>
- **License:** Freely distributed by Brutal Deluxe Software
  (Olivier Zardini, Antoine Vignau). Source published with no
  formal open-source license header -- Brutal Deluxe's "open source
  philosophy" but copyright is retained. Treat as "free to use,
  redistribute as part of a build chain; ask before forking
  commercially."
- **Role:** 65816 cross-assembler. Builds NinjaTrackerPlus.
- **Installed at:** `toolchains/opt/merlin32/` (installer component `merlin32`)

### Bebbo m68k-amigaos GCC toolchain

- **Used on:** Amiga
- **URL:** <https://github.com/AmigaPorts/m68k-amigaos-gcc>
- **License:** GNU GPL v2 (gcc, binutils, libnix); per-component
  copyrights listed in upstream `README.md`. Includes assets covered
  by individual permissive notices (Roadshow, fd2pragma public
  domain, ira freeware, etc.).
- **Role:** AmigaOS HUNK-format gcc + binutils + libnix used to
  compile the Amiga port and link against PTPlayer.
- **Installed at:** `toolchains/opt/amigaGcc/` (installer component `amigaGcc`)

### vasm

- **Used on:** Amiga (PTPlayer only)
- **URL:** <http://sun.hasenbraten.de/vasm/>
- **License:** vasm custom license -- (c) Volker Barthelmann; free for
  non-commercial use, plus an explicit **commercial-use exception
  for M68k + AmigaOS targets** (see vasm distribution README). Other
  commercial use requires written permission. JoeyLib's only
  remaining vasm invocation is `ptplayer.asm` on the Amiga path,
  which falls under the M68k+AmigaOS exception.
- **Role:** Assemble third-party `ptplayer.asm` (Frank Wille's
  Devpac/vasm-syntax source). Our own `.s` files are GAS syntax and
  go through `m68k-amigaos-as` (binutils, GPL) instead.

  sub-project), `toolchains/opt/amigaGcc/bin/vasmm68k_mot`

- **URL:** <https://tho-otto.de/download/mint/>
  (gcc upstream: GNU; mintlib: <https://github.com/freemint/mintlib>)
- **License:** GNU GPL v2 (gcc, binutils); mintlib is a mix of GPL
  and permissive (per-file headers).
- **Role:** GEMDOS-native gcc + binutils + mintlib used to compile
  the Atari ST port.

  GPL v2; DJGPP runtime libraries (libc) are mostly public-domain or
  permissive -- see DJGPP `readme.1st`.
- **Role:** 32-bit protected-mode gcc cross-compiler producing
  COFF binaries that run on 386+ DOS via DPMI.
- **Installed at:** `toolchains/opt/djgpp/` (installer component `djgpp`)

### CWSDPMI

developer's machine. Not part of any redistributed artifact. Installed by
`./install.sh install emulators`.

### MAME

- **Used on:** Apple IIgs (apple2gs driver) and Sharp X68000 (x68k driver)
- **URL:** <https://www.mamedev.org/>
- **License:** GNU GPL v2+ (GPL-2.0-or-later) plus a 3-clause BSD
  alternative for some components.

  the patches in `installer/patches/mame/` (installer component `mame`).

### Hatari

- **Used on:** Atari ST
- **URL:** <https://www.hatari-emu.org/>
- **License:** GNU GPL v2
- **Installed at:** the distribution package on Debian and Ubuntu; on Fedora,

### DOSBox Staging

- **Used on:** DOS

- **Used on:** Atari ST (TOS replacement for Hatari)
- **URL:** <https://emutos.sourceforge.io/>
- **License:** GNU GPL v2
- **Installed at:** `toolchains/firmware/atarist/emutos-512k.img` (installer
  component `emutos`)

---

## System ROMs and disk images (used for testing only)

These are **not** part of JoeyLib distribution. `./install.sh`
places them in `toolchains/firmware/` for emulator-side testing only; see
the source of each before shipping anything that depends on them.

### Downloaded by the installer

- **Apple IIgs MAME ROM sets** (`apple2gs`, ROM 03, `apple2gsr1`, ROM 01,
  and `a2ssc`, the Super Serial Card): Apple Inc. proprietary firmware, from
  the archive.org MAME 0.240 split set. Component `iigsFirmware`.
- **Apple IIgs System 6.0.4** (`System.Disk`): Apple Inc. proprietary OS, from
  the Apple II archive (<https://mirrors.apple2.org.za/>). Component
  `iigsFirmware`.
- **CFFA2 card firmware** (`cffa20eec02.bin`): freely redistributed by
  dreher.net (<https://dreher.net/>). Component `iigsFirmware`.
- **X68000 IPL-ROM and Human68k 3.02 system disk**: from Sharp's own free
  release (2000), published by the X68000 LIBRARY
  (<http://retropc.net/x68000/software/sharp/>). Component `x68kFirmware`.

### Never downloaded (supplied by the user or the project's own bundle)

Installed with `./install.sh import PATH`, or from the bundle a
project hosts (`JOEY_BUNDLE_URL`); matched by the checksums in
`installer/files.sha1`.

- **Amiga Kickstart 3.1 ROM**: Cloanto / Amiga Corp. proprietary, sold today
  (Amiga Forever). Required by the Amiga test gates; `joey-run` falls back to
  FS-UAE's AROS without it. Component `kickstart`.
- **Amiga serial.device 37.4** (Workbench 3.1's `Devs/serial.device`):
  Cloanto / Amiga Corp. proprietary, part of Workbench 3.1 (Amiga Forever).
  Kickstart 3.1 has no serial.device in ROM, so `joey-run` and the Amiga
  serial gate put this copy on the boot drive; `import` also finds it inside
  a Workbench `.adf`. Component `amigaSerial`.
- **X68000 CG (font) ROM**: not part of Sharp's free release. MAME's x68000
  driver needs it. Component `x68kCgrom`.
- **Space Taxi C64 memory image** (`stuff/spacetaxi/raw.bin`): the original
  game's data, from which the example's levels are extracted. Optional.
  Component `staxiData`.

## Maintenance

When adding a new third-party dependency:

1. Append a row in the appropriate section above.
2. Record platform(s), upstream URL, license name, and a one-line
   role description.
3. List where the installer puts it (`toolchains/opt/<component>/` or
   `toolchains/firmware/`).
4. If license terms restrict redistribution, call that out
   explicitly (as we do for Apple ROMs).
