### Dolphin Emulator data files - GPL-2.0-or-later

Copyright (c) 2003+ Dolphin Emulator Project.
Source: <https://github.com/dolphin-emu/dolphin> - license at
<https://github.com/dolphin-emu/dolphin/blob/master/COPYING>

Two data sets from Dolphin's `Data/Sys` tree are redistributed here under GPL-2.0-or-later:

| File(s) | Upstream path | Notes |
| --- | --- | --- |
| `runtime/assets/dsp/dsp_coef.bin` | `Data/Sys/GC/dsp_coef.bin` | Free DSP polyphase-resampling coefficient ROM written by the Dolphin team. 4096 bytes, SHA-256 `D7741279C2E8EC5C5FB318F8FBDD6DE6BF583520D288E836A5383233A4238179`. The runtime verifies this hash at build time. |
| `runtime/assets/wii/shared2/wc24/**` | `Data/Sys/Wii/shared2/wc24` | Dolphin's unmodified default WiiConnect24 bootstrap tree, used to seed a newly created per-user NAND on first run. It is byte-identical to the upstream directory. `nwc24dl.bin` contains Dolphin's default task list, which references Nintendo endpoints shut down in 2014; `nwc24msg.cfg` contains Dolphin's placeholder account fields, not a real user's account data. |

Neither contains Nintendo executable code or game assets; both are redistributed under
GPL-2.0-or-later from Dolphin's `Data/Sys` tree.

SHA-256 hashes for the WiiConnect24 bootstrap tree:

Dolphin was also used extensively as a behavioural reference during development of this project's
hardware and IOS high-level implementations.

### Dolphin Emulator Riivolution code - GPL-2.0-or-later

Copyright (c) 2021 Dolphin Emulator Project.
The runtime's Riivolution patch handling is a port of Dolphin's
`Source/Core/DiscIO/RiivolutionParser.{h,cpp}` and the external-path resolution rules of
`Source/Core/DiscIO/RiivolutionPatcher.cpp`, adapted in
`runtime/include/hle/riivolution_contract.h` and `runtime/src/hle/storage/riivolution.cpp`
(both marked `SPDX-License-Identifier: GPL-2.0-or-later`).
Source: <https://github.com/dolphin-emu/dolphin>

### pugixml - MIT

Copyright (c) 2006-2025 Arseny Kapoulkine.
The Riivolution XML reader uses pugixml 1.15, vendored in
`runtime/third_party/pugixml` from commit `ee86beb30e4973f5feffe3ce63bfa4fbadf72f38`.

### Crypto++ 8.9.0 - Boost Software License 1.0 / public domain

Copyright (c) 1995-2019 Wei Dai and contributors.
The runtime uses Crypto++ for SHA-1 and sect233r1 ECDSA key derivation and signing. Its portable
sources are vendored in `runtime/third_party/cryptopp`; assembly implementations are disabled.

### toml11 4.4.0 - MIT

Copyright (c) 2017 Toru Niina.
The runtime configuration reader and scalar string writer use the single-header distribution,
vendored in `runtime/third_party/toml11`.

### libco - ISC (valgrind.h: BSD-style)

Copyright byuu and the higan team.
Non-Windows builds use libco's symmetric stackful coroutines in place of Win32 Fibers for guest
OSThread scheduling (`runtime/src/fiber_manager.cpp`). Vendored in full (all non-Windows
CPU-architecture backends - amd64, x86, arm, aarch64, ppc, ppc64v2, plus the portable sjlj
fallback - though this project's x86_64-only target only ever compiles amd64.c) in
`runtime/third_party/libco` from commit `e18e09d634d612a01781168ad4d76be10a7e3bad`.

## Fetched at build time and redistributed in release builds

These are pinned in `aurora-main/extern/CMakeLists.txt`, `aurora-main/CMakeLists.txt` and
`aurora-main/cmake/AuroraDawnProvider.cmake`. They are not stored in this repository; the build
downloads them, and release installers carry the resulting binaries. Their license texts are
included in the installer's `licenses/` folder.

compilation can run on a machine with nothing preinstalled. These tools are redistributed
unmodified, with their license texts, in the installer's `licenses/` folder.

## Reference material

Not code, but the documentation this project depends on:

- [WiiBrew](https://wiibrew.org/wiki/) - Wii hardware and IOS documentation.
- [Custom Mario Kart Wiiki (Tockdom)](https://wiki.tockdom.com/) - Mario Kart Wii file formats and
  modding documentation.
- [Retro Rewind](https://wiki.tockdom.com/wiki/Retro_Rewind) by ZPL - the mod distribution this
  project can build as a static profile. No Retro Rewind content is redistributed here; users
  supply their own copy.
