# Third-party notices

The homebrew game, project additions, emulator and compiler runtimes have
different licenses. The game's MIT license does not relicense `core.wasm` or
any third-party source. Original notices must be retained.

## Web distribution

| Component | Source / version | License and distributed notice |
| --- | --- | --- |
| Snes9x / ndssfc derived emulator, including ZSNES-derived code | https://github.com/chegewara/snes9x_esp32/tree/804b8bdad6c49d3831dc2e537af943b9583e0940/components/snes9x | Mixed upstream terms, including Snes9x non-commercial terms and GPL-2.0-or-later notices. Exact upstream text: `licenses/Snes9x.txt`; distributed as `Snes9x-LICENSE.txt`. Do not describe the entire core as MIT or solely GPL. |
| PVSnesLib (linked into the homebrew ROM) | https://github.com/alekmaul/pvsneslib — release 4.6.0 | MIT; `softwares/iron-ring/licenses/PVSnesLib.txt`, distributed as `PVSnesLib-LICENSE.txt`. |
| Emscripten JavaScript runtime (including its Node-derived path helpers) | https://github.com/emscripten-core/emscripten/tree/4.0.23 | MIT / University of Illinois-NCSA; original `web/licenses/Emscripten-LICENSE.txt`, including Node contributor notices. |
| musl C library bundled with Emscripten | https://github.com/emscripten-core/emscripten/tree/4.0.23/system/lib/libc/musl | MIT and additional per-file notices, preserved in `web/licenses/musl-COPYRIGHT.txt`. |
| LLVM libc++, libc++abi, compiler-rt and unwind support bundled with Emscripten | https://github.com/emscripten-core/emscripten/tree/4.0.23/system/lib | Upstream LLVM notices (Apache-2.0 with LLVM exceptions and included legacy notices); see `web/licenses/libcxx-LICENSE.txt`, `libcxxabi-LICENSE.txt`, `compiler-rt-LICENSE.txt`, `libunwind-LICENSE.txt`. |

`web/package.py` copies every `web/licenses/*.txt` file into the same asset
directory as this notice, with those filenames unchanged. `SHA256SUMS` lists
their distribution paths. These are verbatim upstream copies, not new grants.
`web/licenses/GPL-2.0.txt` supplies the unmodified GPL version 2 text referenced
by the emulator notices, obtained from
https://www.gnu.org/licenses/old-licenses/gpl-2.0.txt. The upstream option to
use a later GPL version remains unchanged; this does not remove the separate
Snes9x terms.

Core source, local changes and build instructions are supplied in
`core-source.zip`, beside this notice and the WebAssembly files. Use the
"Source code" link at https://hawkymisc.github.io/ai-comm-fighters/ to download
the archive corresponding to that release. The development repository remains
private; neither repository access nor Git history is required. The archive's
`README.md` and `rebuild.sh` provide standalone build instructions. The adjacent
`BUILD-INFO.json` identifies the archive, embedded ROM and output hashes.

The fixed upstream is fetched by `src/tools/fetch_upstream.sh` and modified by
`src/tools/snes9x-xtensa.patch` and `src/tools/snes9x-CMakeLists.txt`.
`web/CMakeLists.txt` compiles that source list with `web/bridge.cpp`,
`macos/Emulator.cpp` and the repository's host compatibility headers.

## Project content and other targets

- `src/LICENSE` covers the CoreS3 port additions and explicitly excludes the
  fetched Snes9x component. `CoreS3-LICENSE.txt` is its distribution copy.
- `softwares/iron-ring/LICENSE` is the homebrew game's license, distributed as
  `Iron-Ring-LICENSE.txt` (copyright 2026 hawkymisc). The source archive includes
  the same game ROM already supplied inside the WASM, as a rebuild input. This
  independent game has its own license; it is not emulator source. Private
  production art, reports, and past ROMs are not included in the archive.
- `softwares/puzzle-pack/LICENSE` covers the separate Puzzle Lab homebrew and
  shared asset helpers. The Web build embeds only the selected AI-comm Fighters
  ROM, not the Puzzle Lab games or SDK example ROMs.
- ESP-IDF, the M5Stack BSP, ESP codec and USB/HID components are firmware-only
  dependencies. Versions and component licenses are obtained through
  `src/dependencies.lock` and `src/main/idf_component.yml`; they are not linked
  into this WebAssembly build. Review their individual upstream notices when
  distributing firmware. Local SDKs and fetched dependencies are Git-ignored.
- PVSnesLib, Pillow, NumPy, SciPy, the Emscripten SDK and browser-test tools are
  development dependencies fetched separately. Only the runtime portions
  listed above are distributed with the Web game.
