• Windows with Visual Studio 2017 Update 3
• Linux with a modern C++17 friendly compiler
• 64 bit
• OpenGL 4.5
• CMake v3.2+

• None, this is an in-development project and user support is not provided.

The latest Windows AppVeyor build is available from:

• https://ci.appveyor.com/project/exjam/decaf-emu/build/artifacts?branch=master

This project makes use of submodules, please ensure you have cloned them properly using:

• git submodule update --init

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.
