This is the core runtime component for Committee of Zero's MAGES engine game patches for the Nintendo Switch, based on LanguageBarrier. RegionalDialect requires the Atmosphère custom firmware, allowing for asset access redirection, hooking of game engine functions to enable rendering changes, and many more features.
As we try to support all games and any possible patches with a single binary, extensive external configuration is required (in particular, the hooks here won't function without the signatures pointing to their targets). See the root patch repositories (or patched game installations) for details.
CMake and the devkitPro toolchain along with the switch-dev tools and libraries are required to build RegionalDialect. Additionally, a Dockerfile is also provided to build without needing to install the toolchains.
Ensure the DEVKITPRO environment variable is set to the devkitpro toolchain location.
Run cmake to build
cmake --preset Release . && cmake --build . --preset Release
The
CMakePresets.jsonfile contains configuration for the build, parameters can be overridden with command line cache variables, or through a localCMakeUserPresets.json, keep in mind that presets must not share names. For instance, you can add the following to one of the configure presets to override the title ID to use Chaos;Head NoAH.
"cacheVariables": {
"TITLE_ID": "0100c17017cbc000"
}
Build the docker image
docker build -t regiondialect-build .
Run the container and mount it to the project directory, you can substitute <PROJECT_DIRECTORY> with ${PWD} on PowerShell and %cd% on bash
docker run --rm -it -v <PROJECT_DIRECTORY>:/workspace regiondialect-build bash
Run cmake to build
cmake --preset Release . && cmake --build . --preset Release
Add in the flag -DTITLE_ID=<game_id_here> to generate a npdm with the corresponding game's title ID.
Once built, copy the subsd9 file into the exefs directory corresponding to the game. A gamedef.json and main.npdm file tailored to the specific game is also necessary for the mod to function.
