### Install Dynarmic with CMake package config

Source: https://github.com/zortos293/lichii/blob/nx2/src/dynarmic/CMakeLists.txt

Installs the dynarmic target, exports it with the dynarmic:: namespace, generates and installs package config files, and installs headers when DYNARMIC_INSTALL is enabled.

```cmake
if (DYNARMIC_INSTALL)
    include(GNUInstallDirs)
    include(CMakePackageConfigHelpers)

    install(TARGETS dynarmic EXPORT dynarmicTargets)
    install(EXPORT dynarmicTargets
        NAMESPACE dynarmic::
        DESTINATION "${CMAKE_INSTALL_LIBDIR}/cmake/dynarmic"
    )

    configure_package_config_file(CMakeModules/dynarmicConfig.cmake.in
        dynarmicConfig.cmake
        INSTALL_DESTINATION "${CMAKE_INSTALL_LIBDIR}/cmake/dynarmic"
    )
    write_basic_package_version_file(dynarmicConfigVersion.cmake
        COMPATIBILITY SameMajorVersion
    )
    install(FILES
        "${CMAKE_CURRENT_BINARY_DIR}/dynarmicConfig.cmake"
        "${CMAKE_CURRENT_BINARY_DIR}/dynarmicConfigVersion.cmake"
        DESTINATION "${CMAKE_INSTALL_LIBDIR}/cmake/dynarmic"
    )

    install(DIRECTORY src/dynarmic TYPE INCLUDE FILES_MATCHING PATTERN "*.h")
endif()
```

--------------------------------

### Run compatibility report tests with preview and screenshot options

Source: https://github.com/zortos293/lichii/blob/nx2/docs/compatibility-report.md

Runs the compatibility report test binary with a synthetic dialog using fake transport. The preview preloads synthetic experience text for visual inspection; the screenshot option uses offscreen platform. Do not submit synthetic fixtures to the live website.

```sh
build/compatibility-report/compatibility_report_tests --preview
QT_QPA_PLATFORM=offscreen build/compatibility-report/compatibility_report_tests \
  --screenshot /tmp/compatibility-report.png
```

--------------------------------

### Enable EDEN_DKB_INDIRECT_READBACK and launch eden.exe

Source: https://github.com/zortos293/lichii/blob/nx2/docs/bananza-diagnostics.md

Run in PowerShell for a second run focused on the black image. This copies actual GPU indirect arguments instead of potentially stale guest-memory copies. It adds render-pass breaks and transfer barriers, so use the first run for timing comparisons. If enabling readback changes the symptom, report that fact; the readback is diagnostic, not a rendering fix.

```powershell
$env:EDEN_DKB_INDIRECT_READBACK = "1"
& .\eden.exe
```

--------------------------------

### Run adapter with --call for single requests

Source: https://github.com/zortos293/lichii/blob/nx2/docs/nx2/debug-mcp.md

Uses native Windows Python to run the adapter. --call sends one request, prints JSON result, and saves PNG to --out. On failure prints {"error": ...} and exits with status 1.

```bash
PY=/c/Users/Zortos/AppData/Local/Programs/Python/Python314/python.exe
$PY -I C:/lx/src/tools/nx2/debug_mcp.py --server 127.0.0.1:6545 --call '{"method":"status"}'
$PY -I C:/lx/src/tools/nx2/debug_mcp.py --server 127.0.0.1:6545 \
    --call '{"method":"screenshot","params":{"height":1080}}' --out C:/lx/shot.png
$PY -I C:/lx/src/tools/nx2/debug_mcp.py --server 127.0.0.1:6545 \
    --call '{"method":"reject_shaders","params":{"hashes":["3ddfb1d7621c4755"]}}'
$PY -I C:/lx/src/tools/nx2/debug_mcp.py --server 127.0.0.1:6545 \
    --call '{"method":"input_sequence","params":{"steps":[{"right_stick":[1,0],"frames":60},{"frames":30}]}}'
```

--------------------------------

### Configure Eden build with CMake

Source: https://github.com/zortos293/lichii/blob/nx2/NX2_NOTES.md

Configures the Eden build using CMake with Ninja and MSVC. Uses a short intermediate directory strategy to avoid PDB path length issues (C1041). Disables Qt, web service, room, tests, Werror, and update checker.

```shell
cmake -S . -B build -G Ninja -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_INTERMEDIATE_DIR_STRATEGY=SHORT -DENABLE_QT=OFF -DYUZU_CMD=ON -DENABLE_WEB_SERVICE=OFF -DYUZU_ROOM=OFF -DYUZU_TESTS=OFF -DENABLE_WERROR=OFF -DENABLE_UPDATE_CHECKER=OFF
```

--------------------------------

### Set Visual Studio startup project based on ENABLE_QT

Source: https://github.com/zortos293/lichii/blob/nx2/CMakeLists.txt

Sets the default startup project in Visual Studio to 'yuzu' when ENABLE_QT is enabled, otherwise 'yuzu-cmd'.

```cmake
if(ENABLE_QT)
    set_property(DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} PROPERTY VS_STARTUP_PROJECT yuzu)
else()
    set_property(DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} PROPERTY VS_STARTUP_PROJECT yuzu-cmd)
endif()
```

--------------------------------

### Run eden-cli with GDB stub

Source: https://github.com/zortos293/lichii/blob/nx2/docs/Debug.md

Run the emulator with GDB stub enabled. Replace <path to your config file> and <path to game> with actual paths.

```bash
./build/bin/eden-cli -c <path to your config file (see logs where you run Eden normally to see where it is)> -d -g <path to game>
```

--------------------------------

### Build yuzu-cmd and tests

Source: https://github.com/zortos293/lichii/blob/nx2/docs/bananza-diagnostics.md

Builds the yuzu-cmd and tests targets in parallel using Ninja.

```sh
cmake --build build --target yuzu-cmd tests --parallel "$(nproc)"
```

--------------------------------

### macOS: Install additional MoltenVK dependencies

Source: https://github.com/zortos293/lichii/blob/nx2/docs/Deps.md

Installs additional dependencies required to run with MoltenVK on macOS.

```sh
sudo pkg install git cmake ffmpeg6 zlib llvm18
```

--------------------------------

### Configure and build with Aftermath SDK enabled

Source: https://github.com/zortos293/lichii/blob/nx2/docs/STARFOX_AFTERMATH_DIAGNOSTIC.md

Sets the process-local NSIGHT_AFTERMATH_SDK environment variable, then creates and runs a modified configure script that changes the build directory to C:/lx/build-aftermath and adds -DENABLE_NSIGHT_AFTERMATH:BOOL=ON. Finally builds with cmake --build C:/lx/build-aftermath --parallel 12. Requires the SDK headers (include/GFSDK_Aftermath_GpuCrashDump.h) in the SDK directory; the ordinary Windows build does not define HAS_NSIGHT_AFTERMATH.

```sh
export NSIGHT_AFTERMATH_SDK='C:/lx/deps/nsight-aftermath-2026.3.0'
sed \
  -e 's@-B C:/lx/build @-B C:/lx/build-aftermath @' \
  -e 's@-DCMAKE_BUILD_TYPE=RelWithDebInfo@-DCMAKE_BUILD_TYPE=RelWithDebInfo -DENABLE_NSIGHT_AFTERMATH:BOOL=ON@' \
  C:/lx/configure.sh > C:/lx/configure-aftermath.sh
bash C:/lx/configure-aftermath.sh
cmake --build C:/lx/build-aftermath --parallel 12
```

```

--------------------------------

### Deploy Qt DLLs and plugins for Windows

Source: https://github.com/zortos293/lichii/blob/nx2/src/yuzu/CMakeLists.txt

Copies Qt DLLs and plugins next to the executable on Windows when not using bundled Qt. Uses windeployqt, generating a qt.conf file and a POST_BUILD command. Warns if windeployqt is not found.

```cmake
if (WIN32 AND NOT YUZU_USE_BUNDLED_QT)
    # Copy the Qt DLLs and plugins next to the executable. WINDEPLOYQT_EXECUTABLE was never set, so
    # this step ran the emulator itself with windeployqt's arguments and failed every build that
    # uses an installed Qt (the Windows release workflow).
    if (TARGET Qt6::windeployqt)
        set(WINDEPLOYQT_EXECUTABLE "$<TARGET_FILE:Qt6::windeployqt>")
    else()
        find_program(WINDEPLOYQT_EXECUTABLE NAMES windeployqt6 windeployqt
                     HINTS "${QT_HOST_PATH}/bin" "${QT_TARGET_PATH}/bin")
    endif()
    file(GENERATE OUTPUT "$<TARGET_FILE_DIR:yuzu>/qt.conf"
         CONTENT "[Paths]\nPrefix=.\nPlugins=plugins\n")
    if (WINDEPLOYQT_EXECUTABLE)
        set(YUZU_EXE_DIR "$<TARGET_FILE_DIR:yuzu>")
        add_custom_command(TARGET yuzu POST_BUILD COMMAND ${WINDEPLOYQT_EXECUTABLE} "$<TARGET_FILE:yuzu>" --dir "${YUZU_EXE_DIR}" --libdir "${YUZU_EXE_DIR}" --plugindir "${YUZU_EXE_DIR}/plugins" --no-compiler-runtime --no-opengl-sw --no-system-d3d-compiler --no-translations --verbose 0)
    else()
        message(WARNING "windeployqt not found: copy the Qt DLLs next to the executable yourself")
    endif()
endif()
```

Source: https://github.com/zortos293/lichii/blob/nx2/docs/bananza-diagnostics.md

Use CMake 3.31 or newer and a Clang version that accepts -mtls-dialect=gnu2. The cloud check uses Clang 20 because Ubuntu's Clang 18 rejects that flag. ENABLE_WERROR=OFF is required for pre-existing Clang warnings in the audio tests.

```sh
cmake -S . -B build -G Ninja \
  -DCMAKE_C_COMPILER=clang-20 -DCMAKE_CXX_COMPILER=clang++-20 \
  -DCMAKE_BUILD_TYPE=RelWithDebInfo -DENABLE_QT=OFF \
  -DYUZU_CMD=ON -DYUZU_TESTS=ON -DENABLE_LTO=OFF \
  -DENABLE_WEB_SERVICE=OFF -DUSE_DISCORD_PRESENCE=OFF -DENABLE_WERROR=OFF
```

--------------------------------

### OpenIndiana: Create cc wrapper for dependencies

Source: https://github.com/zortos293/lichii/blob/nx2/docs/Caveats.md

Creates a local `cc` wrapper that calls `gcc` and adds it to PATH. Needed for some dependencies that call cc directly (e.g., tz).

```sh
echo '#!/bin/sh -e' >cc
echo 'gcc $@' >>cc
chmod +x cc
export PATH="$PATH:$PWD"
```

--------------------------------

### Install dependencies on Fedora

```

--------------------------------

### Create eden.sh launcher script for EmuDeck

Source: https://github.com/zortos293/lichii/blob/nx2/docs/user/SteamROM.md

Paste this shell script into the eden.sh file created in the EmuDeck tools/launchers directory. It initializes the emulator, finds the Eden AppImage, makes it executable, launches it, and performs cloud sync cleanup.

```bash
#!/bin/sh -e
emuName="eden" #parameterize me

. "$HOME/.config/EmuDeck/backend/functions/all.sh"
emulatorInit "$emuName"

# find full path to emulator appimage
appimage=$(find "$emusFolder" -iname "${emuName}*.AppImage" -print -quit 2>/dev/null)

# make sure the appimage is executable
	chmod +x "$appimage"
	set -- "$appimage" "$@"

echo "Launching ${emuName} with:" "$@"
"$@"

cloud_sync_uploadForced
rm -rf "$savesPath/.gaming"

```

--------------------------------

### Build and test commands for verification

Source: https://github.com/zortos293/lichii/blob/nx2/docs/VideoPlaybackUpstreamAudit.md

Commands to configure, build, and run tests for the port. Uses clang 20 because clang 18 rejects the existing -mtls-dialect=gnu2 flag. The focused H.264 and mapping selection runs eight cases and 1,089 assertions.

```sh
cmake -S . -B build -G Ninja \
  -DCMAKE_C_COMPILER=clang-20 -DCMAKE_CXX_COMPILER=clang++-20 \
  -DCMAKE_BUILD_TYPE=RelWithDebInfo \
  -DENABLE_QT=OFF -DYUZU_CMD=ON -DYUZU_TESTS=ON -DENABLE_WERROR=OFF

    COMMAND
        nproc
    OUTPUT_VARIABLE
        SYSTEM_THREADS)
```

--------------------------------

### Create ZFS dataset with zstd compression

Source: https://github.com/zortos293/lichii/blob/nx2/docs/user/Storage.md

Creates a ZFS dataset named zroot/switch and enables zstd compression. The dataset is then available at /zroot/switch and can be added as a game directory. Ensure proper permissions with chmod 755 /zroot/switch/*.

```sh
sudo zfs create zroot/switch`
sudo zfs set compression=zstd zroot/switch
```

--------------------------------

### Configure CMake for cross-compilation

Source: https://github.com/zortos293/lichii/blob/nx2/docs/CrossCompile.md

Configure the project with CMake using the Gentoo cross toolchain file, setting CROSS_TARGET and disabling OpenGL.

```sh
cmake -S . -B build/aarch64 -DCMAKE_TOOLCHAIN_FILE=CMakeModules/toolchains/GentooCross.cmake -GNinja -DCROSS_TARGET=aarch64 -DENABLE_OPENGL=OFF
```

--------------------------------

### Add license headers with amend commit

Source: https://github.com/zortos293/lichii/blob/nx2/docs/Development.md

```

--------------------------------

### Enable RenderDoc capture on Windows PowerShell

Source: https://github.com/zortos293/lichii/blob/nx2/docs/Debug.md

Sets the ENABLE_VULKAN_RENDERDOC_CAPTURE environment variable to '1' and launches eden.exe so RenderDoc can attach before the Vulkan device is created. The default Windows capture folder is %LOCALAPPDATA%\Temp\RenderDoc.

```powershell
$env:ENABLE_VULKAN_RENDERDOC_CAPTURE='1'
.\eden.exe
```

--------------------------------

### Build Eglantine with CMake and Ninja

Source: https://github.com/zortos293/lichii/blob/nx2/docs/Build.md

Configure and build Eglantine in Release mode using CMake with the Ninja generator. Requires a development environment with dependencies installed.

```sh
cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -G Ninja
cmake --build build
```

--------------------------------

### Build glslang on OmniOS

Source: https://github.com/zortos293/lichii/blob/nx2/docs/Caveats.md

Required on OmniOS because dependencies are missing. Do not use `-t glslang`; it causes installation to fail. Use `--parallel` with caution due to a CMake bug on OmniOS.

```sh
sudo pkg install python-313
git clone --depth=1 https://github.com/KhronosGroup/glslang.git
cd glslang
python3.13 ./update_glslang_sources.py
cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build -- -j `nproc`
cmake --install build
```

--------------------------------

### Manage the Docker container
