RALibretro is a multi-emulator that can be used to develop RetroAchievements and, of course, earn them.

The "multi-emulation" feature is only possible because it uses libretro cores to do the actual emulation. What RALibretro does is to connect the emulation to the tools used to create RetroAchievements.

The integration with RetroAchievements.org site is done by the RAIntegration.

1. Go to http://www.msys2.org/ and download the 32 bit version.
2. Follow the installation instructions on the site http://www.msys2.org/.
3. When on the prompt for the first time, run pacman -Syu (NOTE: at the end of this command it will ask you to close the terminal window without going back to the prompt.)
4. Launch the MSYS2 terminal again and run pacman -Su

$ pacman -S make git zip mingw-w64-i686-gcc mingw-w64-i686-SDL2 mingw-w64-i686-gcc-libs

$ git clone --recursive --depth 1 https://github.com/RetroAchievements/RALibretro.git

$ cd RALibretro
$ make

NOTE: use make for a release build or make DEBUG=1 for a debug build. Don't forget to run make clean first if switching between a release build and a debug build.
