Emulators: Retroarch


Recommended Posts


RetroArch is a modular multi-system emulator system that is designed to be fast, lightweight and portable. It has features few other emulator frontends have, such as real-time rewinding and game-aware shading.


  • Real-time rewinding.
  • Switching between emulator cores seamlessly, and ability to install new libretro cores.'


Copy the entire folder RetroArch-XBox1 to your harddrive.

ROMs go into the roms directory, or some subdirectory in the RetroArch-XB1 directory.

About libretro

Libretro is the API that RetroArch uses. It makes it easy to port games and emulators to a single core backend, such as RetroArch.

For the user, this means - more ports to play with, more crossplatform portability, less worrying about developers having to reinvent the wheel writing boilerplate UI/port code - so that they can get busy with writing the emulator/porting the emulator/game.


For each emulator core, RetroArch makes use of a library API that we call libretro.

Think of libretro as an interface for emulator and game ports. You can make a libretro port once and expect the same code to run on all the platforms that RetroArch supports. It's designed with simplicity and ease of use in mind so that the porter can worry about the port at hand instead of having to wrestle with an obfuscatory API.

How to use

On first startup, RetroArch will select one of the dozen or so emulator/game cores. The name of the core currently loaded will be shown at the top side of the screen.

You can now select a data file (ie. a game executable and/or a ROM) that this core supports and load it in the Filebrowser.

To select a different core - go to Core in the Main Menu. Select a core and then press A to switch to the emulator/game core.

Selecting a ZIP file will temporarily unzip that file to the harddrive. The temporary file will be deleted as soon as the game gets unloaded and/or when you quit RetroArch.

Note: If you find that RetroArch no longer works for whatever reason, try removing retroarch.cfg from the Retroarch-XB1 folder, then start up again.
