Building the project is for users that want to contribute code only. If you wish to build the emulator yourself, follow these steps:
Install the .NET 8.0 (or higher) SDK. Make sure your SDK version is higher or equal to the required version specified in global.json.
Either use git clone https://github.com/GreemDev/Ryujinx on the command line to clone the repository or use Code --> Download zip button to get the files.
To build Ryujinx, open a command prompt inside the project directory.
You can quickly access it on Windows by holding shift in File Explorer, then right clicking and selecting Open command window here.
Then type the following command: dotnet build -c Release -o build
the built files will be found in the newly created build directory.
Ryujinx system files are stored in the Ryujinx folder.
This folder is located in the user folder, which can be accessed by clicking Open Ryujinx Folder under the File menu in the GUI.
