There are two decaf frontends:
- decaf-sdl - Default emulator target using SDL for window creation and input.
- decaf-cli - Command line only which will run games with no graphics or inputs, useful for test .rpx files.
- Use CMake to generate a solution
cmake ../decaf-emu && make- It is suggested (but optional) to use your system's zlib, sdl2 and glbinding
- You can enable building with valgrind with -DDECAF_VALGRIND=ON, this requires valgrind to be installed on your system
- Requires a modern gcc or clang which supports C++17 features
./decaf-sdl play <path to game>
It is recommended to run the emulator from the root git directory so that it is able to access resources/fonts/*. Alternatively, set resources_path in the configuration file to point to the resources directory.
Configuration files can be found at:
- Windows -
%APPDATA%\decaf - Linux -
~/.config/decaf
On Linux, a "Bus error" crash usually indicates an out-of-space error in the temporary directory. Set the TMPDIR environment variable to a directory on a filesystem with at least 2GB free.
