./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.
