RetroArch is the reference frontend for the libretro API. Popular examples of implementations for this API includes video game system emulators and game engines as well as more generalized 3D programs. These programs are instantiated as dynamic libraries. We refer to these as "libretro cores".

libretro is an API that exposes generic audio/video/input callbacks. A frontend for libretro (such as RetroArch) handles video output, audio output, input and application lifecycle. A libretro core written in portable C or C++ can run seamlessly on many platforms with very little to no porting effort.

While RetroArch is the reference frontend for libretro, several other projects have used the libretro interface to include support for emulators and/or game engines. libretro is completely open and free for anyone to use.

RetroArch attempts to be small and lean while still having all the useful core features expected from an emulator. It is designed to be very portable and features a gamepad-centric and touchscreen UI. It also has a full-featured command-line interface.

In some areas, RetroArch goes beyond and emphasizes on not-so-common technical features such as multi-pass shader support, real-time rewind (Braid-style), video recording (using FFmpeg), run-ahead input latency removal, etc.

RetroArch also emphasizes being easy to integrate into various launcher frontends.


RetroArch has been ported to the following platforms:

  • DOS
  • Windows
  • Linux
  • Emscripten (WebAssembly and JavaScript)
  • FreeBSD
  • NetBSD
  • OpenBSD
  • Haiku
  • Solaris
  • macOS (PPC, x86-32 and x86-64)
  • PlayStation 2
  • PlayStation 3
  • PlayStation Portable
  • PlayStation Vita
  • Original Microsoft Xbox
  • Microsoft Xbox 360 (Libxenon/XeXDK)
  • Nintendo GameCube
  • Nintendo Wii
  • Nintendo Wii U
  • Nintendo 3DS/2DS
  • Nintendo Switch
  • Nintendo NES/SNES Classic Edition
  • Raspberry Pi
  • Android
  • iOS
  • Blackberry

Dependencies (PC)

There are no true hard dependencies per se.

On Windows, RetroArch can run with only Win32 as dependency.

On Linux, there are no true dependencies. For optimal usage, the following dependencies come as recommended:

  • GL headers / Vulkan headers
  • X11 headers and libs, or EGL/KMS/GBM

OSX port of RetroArch requires latest versions of XCode to build.

RetroArch can utilize these libraries if enabled:

  • nvidia-cg-toolkit
  • libfreetype2 (TTF font rendering on screen)

RetroArch needs at least one of these audio driver libraries:

  • ALSA
  • OSS
  • RoarAudio
  • RSound
  • OpenAL
  • JACK
  • SDL
  • PulseAudio
  • XAudio2 (Win32, Xbox 360)
  • DirectSound (Win32, Xbox 1)
  • CoreAudio (OSX, iOS)

To run properly, RetroArch requires a libretro implementation present; however, as it's typically loaded dynamically, it's not required at build time.

Dependencies (Console ports, mobile)

Console ports have their own dependencies, but generally do not require anything other than what the respective SDKs provide.


The default configuration is defined in config.def.h. It is not recommended to change this unless you know what you're doing. These can later be tweaked by using a config file. A sample configuration file is installed to /etc/retroarch.cfg. This is the system-wide config file.

RetroArch will on startup create a config file in $XDG\_CONFIG\_HOME/retroarch/retroarch.cfg if it does not exist. Users only need to configure a certain option if the desired value deviates from the value defined in config.def.h.

To configure joypads, use the built-in menu or the retroarch-joyconfig command-line tool.

Compiling and installing

Instructions for compiling and installing RetroArch can be found in the Libretro/RetroArch Documentation Center.

CRT 15Khz Resolution Switching

CRT SwitchRes will turn on, on the fly. However, you will need to restart RetroArch to disable it. With CRT SwitchRes enable RetroArch will start in 2560 x 480 @ 60.

If you are running Windows, before enabling the CRT SwitchRes options please make sure you have installed CRTEmudriver and installed some modelines. The minimum modelines for all games to switch correctly are:

  • 2560 x 192 @ 60.000000
  • 2560 x 200 @ 60.000000
  • 2560 x 240 @ 60.000000
  • 2560 x 224 @ 60.000000
  • 2560 x 237 @ 60.000000
  • 2560 x 256 @ 50.000000
  • 2560 x 254 @ 55.000000
  • 2560 x 448 @ 60.000000
  • 2560 x 480 @ 60.000000

Install these modelines replacing 2560 with your desired super resolution. The above resolutions are NTSC only so if you would be playing any PAL content please add PAL modelines:

  • 2560 x 192 @ 50.000000
  • 2560 x 200 @ 50.000000
  • 2560 x 240 @ 50.000000
  • 2560 x 224 @ 50.000000
  • 2560 x 288 @ 50.000000
  • 2560 x 237 @ 50.000000
  • 2560 x 254 @ 55.000000
  • 2560 x 448 @ 50.000000
  • 2560 x 480 @ 50.000000

Some games will require higher PAL resolutions which should also be installed:

  • 2560 x 512 @ 50.000000
  • 2560 x 576 @ 50.000000

Ideally install all these modelines and everything will work great.

Super Resolutions

The default super resolution is 2560. It is displayed just under the CRT switch option, which can be found in video settings. This can be changed within the retroarch.cfg. The only compatible resolutions are 1920, 2560 and 3840. Any other resolutions will be ignored and native switching will be activated.

Native Resolutions

If native resolutions are activated you will need a whole new set of modelines:

These modelines are more accurate giving exact hz. However, some games may have unwanted results. This is due to mid-scanline resolution changes on the original hardware. For the best results super resolutions are the way to go.

CRT resolution switching & MAME

Some arcade resolutions can be very different from consumer CRTs. There is resolution detection to ensure MAME games will be displayed in the closest available resolution but drawn at their native resolution within this resolution. Meaning that the MAME game will look just like the original hardware.

MAME ROMs that run in a vertical aspect like DoDonPachi need to be rotated within MAME before resolution switching and aspect correction will work. Do this before enabling CRT SwitchRes so that RetroArch will run in your desktop resolution. Once you have rotated any games that may need it turn CRT SwitchRes on.

  • Niche issue when streaming RA using some shader presets

    Niche issue when streaming RA using some shader presets

    First and foremost consider this:

    • Only RetroArch bugs should be filed here. Not core bugs or game bugs
    • This is not a forum or a help section, this is strictly developer oriented

    This is probably exceptionally low priority and something i'll have to live with. Still - I wanted to make sure it was put out there. As of a few versions back, I am no longer able to stream RA properly, at least in the means I have for a long time now. Unfortunately I'm a serial updater, and ive had a good week off of playing, so i cant say exactly what or when caused the regression.

    The short of it is this.

    I have content directory shader presets set up. In this case, for beetle psx hw. I load a game from said playlist, config override kicks in and positions window properly/places within overlay, and shader preset kicks in which ties into the configured sizing present in the config.

    this has stopped working if I am streaming and if im using my go-to shader that I have set up (ctr guest dr venom.) I stream via steam BPM via steam link app and if I load retroarch and load any playlist which uses that shader, I get a black screen with audio. This also happens with several other higher end crt shaders.

    If i come back to my pc, the image is on the screen, but is without color. If i remove the shader preset, all is fine. If i load a basic shader such as Geom's as a preset, that works fine as well.

    One other oddity. If i load a game via command line/shortcut direct from steam, it works fine. ONLY if i load it via retroarch itself does it fail.

    Im not sure if something a few versions back changed the priority or order these things were drawn or loaded - but definitely puts a damper on my vastly preferred means of playing.

    at current my options are command line shortcuts/launching of any game i want to play that uses that shader. The removal of those shader presets entirely from ~30 playlists and go with something basic like geoms, and resize all my config files to accomodate. Or, play exclusively from my pc.

    This could very well stem elsewhere, however I did try several different gpu drivers just in case. Also tried removing curve to eliminate that as being a potential variable as i know royale fails when curve is added to the picture.

    The strange part is, if i remove the preset, and load it manually after the game is loaded - it works just fine as well. its purely giving me hell when loaded automatically via content directory preset.

    Expected behavior

    The game to display alongside overlay AND shader, instead of overlay + black screen + audio.

    Actual behavior

    See above.

    Steps to reproduce the bug

    1. Launch retroarch via (presumably) a steam link - or in my case the steam link app.
    2. Load a game from a playlist that uses crt-guest-dr-venom
    3. note everything loads, (can see overlay, audio is playing) the gameplay area is black.

    Bisect Results

    I cant say exactly, as ive been not playing (but updating) for the past week or so. But its very recent.

  • Video width and height are switched when a vertically-oriented game is loaded

    Video width and height are switched when a vertically-oriented game is loaded


    With vertically oriented games, Retroarch switches the emulator-provided width and height. For example, if the width/height is supposed to be 320x240, RA will switch this to 240x320. This only occurs with vertically oriented games. I tested this in both MAME and FBA using the Windows 64 bit version of RA.

    Expected behavior

    The game to be displayed using the correct resolution (width/height).

    Actual behavior

    The height and width is switched when a vertically oriented game is loaded.

    Steps to reproduce the bug

    1. load any vertically oriented game in either FBA or MAME using Windows 64 bit version of RA (example: DonPachi)
    2. under video settings, enable integer scale.
    3. set "custom aspect ratio width/height" to 1x.
    4. look at "custom aspect ratio width/height" to see that it says 240 for width and 320 for height. This is the reverse of what it should be; it should be 240 for height and 320 for width.

  • Vulkan video driver in fullscreen on GeForce Driver 387.92 causing black screen

    Vulkan video driver in fullscreen on GeForce Driver 387.92 causing black screen


    With the new nVidia GeForce 387.92 video driver, the RetroArch Vulkan video driver only displays a black screen when starting any emulator. This only occurs in fullscreen mode. If you run in Windowed mode or alt-tab out of RetroArch and back in, then you'll get an image again (unless you change a resolution setting in the emulator causing the video driver to initialize).

    nVidia's driver release notes say the following relating to the issue:

    Implemented improved behavior for full-screen Vulkan swapchains using VK_KHR_win32_surface.

    This optimization will cause more events that trigger an out-of-date swapchain, such as when entering or leaving full-screen mode (typically by pressing Alt+tab). Applications that do not properly respond to the VK_ERROR_OUT_OF_DATE_KHR return code may not function properly when these events occur. See the WSI Swapchain section of the Vulkan specification.

    Other users reporting the issue here:

    Expected behavior

    Video to be displayed normally.

    Actual behavior

    Screen goes black when starting any emulator

    Steps to reproduce the bug

    1. Install nVidia Geforce Driver 387.92
    2. Start any emulator in-game
    3. Experience the black screen
    4. Exit Fullscreen or simply alt-tab out and back in to get the image back

    Bisect Results

    Only occurs with 387.92 and up nVidia driver. Rolling back to 385.69 works fine.

I tap the home button and it's running in the background, switch to it, and I'm returned (once again) to my icons.

    [Feature Request] "Quit RetroArch" menu option for iOS


    RetroArch on iOS does not have the Quit option in the main menu.

    Not sure if the option missing is a technical feature implemented over the years, but at least on modern iOS I can quit gracefully by hitting ESC twice on a keyboard. Can the same quit hook be used for the menu option?

    What ends up happening is I change some settings and inevitably forget to save the config manually, quit via the application switcher (which is NOT GRACEFUL), and it doesn't auto save the config (works when pressing ESC twice)

    Expected behavior

    Being able to exit RetroArch via the menu (either via touch or controller)

    Actual behavior

    Option is missing.

    This PR adds new hotkeys for directly saving and loading into save states. More details:

    • The savestate_max_direct_slot setting determines the highest slot that can be used with the hotkeys. For example, if this value is 1, hotkeys for directly saving and loading slots 0 and 1 can be used. This defaults to -1, which disables the feature.
    • Similarly, the options and bindings for the direct slots won't show up in the Hotkeys menu if the slot is greater than savestate_max_direct_slot.
    • None of the new hotkeys are binded by default.

  • Add environment callback to get the rate retro_run is called

    Add environment callback to get the rate retro_run is called


    In my endeavor to add automatic performance scaling to a non-multi-threaded DOSBox core I ran into the problem that a core cannot feasibly distinct between these 3 scenarios:

    • The core uses too much CPU time
    • The user has activated slow-motion
    • VSync is active and limiting the call-rate of retro_run

    Only the first of these scenarios actually require the core to lower it's automatically scaling performance requirements. Without this extension I cannot properly support the features used in the other two scenarios while automatic performance scaling is active.

    So this PR adds a new environment callback RETRO_ENVIRONMENT_GET_THROTTLE_STATE to ask the frontend about some details on what the actual rate it tries to call retro_run() and why.

    The relevant sections of the API are as follows:

                                               /* struct retro_throttle_state * --
                                                * Allows an implementation to get details on the actual rate
                                                * the frontend is attempting to call retro_run().
    enum retro_throttle_mode
       /* During normal operation, rate will be equal to the core's FPS. */

       /* During fast forwarding.

       /* During slow motion. Rate will be less than the core's internal FPS. */
       /* Rewinding recorded save states. Rate can vary depending on the rewind
        * speed or be 0 if the frontend is not aiming for a specific rate. */
       RETRO_THROTTLE_REWINDING         = 4,
       /* While vsync is active in the video driver and the target refresh rate is
        * lower than the core's internal FPS. Rate is the target refresh rate. */
       RETRO_THROTTLE_VSYNC             = 5,
    struct retro_throttle_state
       /* The current throttling mode. */
       enum retro_throttle_mode mode;
       /* How many times per second the frontend tries calls retro_run.
        * Depending on the mode, it can be 0 if there is no known fixed rate.
        * This won't be accurate if the total processing time of the core and
        * the frontend is longer than what is available for one frame. */
       float rate;

    (I appended | RETRO_ENVIRONMENT_EXPERIMENTAL because RETRO_ENVIRONMENT_GET_FASTFORWARDING also has it, not sure if that is needed or not)

    If this environment callback is available, it can be used instead of RETRO_ENVIRONMENT_GET_FASTFORWARDING. A core can be backwards compatible by using something like this:

    	retro_throttle_state throttle = { RETRO_THROTTLE_NONE };
    	if (!environ_cb(RETRO_ENVIRONMENT_GET_THROTTLE_STATE, &throttle))
    		bool fast_forward = false;
    		if (environ_cb(RETRO_ENVIRONMENT_GET_FASTFORWARDING, &fast_forward) && fast_forward)
    			dbp_throttle.mode = RETRO_THROTTLE_FAST_FORWARD;

    This is my first PR that modifies libretro.h so I'm open to any feedback or request for change.

    No sound in recorded or streamed video stream


    While recording to a local file, or streaming, there is no sound included in the video stream.

    Expected behavior

    Sound included in the stream.

    Actual behavior

    Both recording to a local file, as well as streaming to twitch, seems to work perfectly, except for the little annoyance of there being no sound produced in the stream.

    The sound in the game itself, while playing, is there.

    I'm using pulseaudio, and this is what ffprobe has to say about a recorded file:

    [Feature Request] APNG support

    While somewhat infrequently used in general, apng support would allow users to add motion screenshots for their games, animated backgrounds, and -potentially- animated achievement icons down the line (I won't be pursuing implementation of that unless support can be added). I inquired on Discord and apparently it -appears- it should be simple to implement. Of course, as with anything involving the menu code, I realize that may be far from the truth.

  • [3DS] Vertical games rotate the top screen the wrong way

    [3DS] Vertical games rotate the top screen the wrong way

    First and foremost consider this:

    • Only RetroArch bugs should be filed here. Not core bugs or game bugs
    • This is not a forum or a help section, this is strictly developer oriented


    This is easiest seen with the Beetle Cygne core for WonderSwan, since with that core you can press the select button to rotate the screen.

    This has also been reported with Final Burn cores:

    Screenshots from WonderSwan, before and after pressing select: landscape portrait

    Expected behavior

    Vertical screen is right side up.

    Actual behavior

    Vertical screen is upside down.

    Steps to reproduce the bug

    1. Open up content for the Beetle Cygne core for WonderSwan.
    2. Press the select button.

    Bisect Results

    No idea.

  • New feature: Use gamepad combo to quit Retroarch

    New feature: Use gamepad combo to quit Retroarch


    This is my first Retroarch PR, so please be kind and thorough in code review!

    I built a home arcade with Retroarch. It has no keyboard, just arcade-style joysticks and buttons. I found my young kids couldn't quite understand how to quit Retroarch with the buttons.

    I found the "toggle menu with gamepad combo" feature, and tried to teach my kids how to navigate to the quit option from there, but they couldn't figure it out.

    I tried setting up AutoHotKey to map various joystick buttons to the ESC key on the keyboard, but it's fairly flaky and doesn't handle joysticks being plugged/unplugged (we have Bluetooth gamepads that we use from time to time).

    So, this PR builds on the existing "toggle menu with gamepad combo" feature and:

    1. Refactors the existing "toggle menu" logic and gamepad combo-related enums so they can be reused for non-menu-toggling features
    2. Moves the static timers for the "hold start" / "hold select" combos out into input_driver_state_t so they can be used separately for the "toggle menu" feature and other features which use a gamepad combo
    3. Adds a new config option and menu entry to quit Retroarch with a gamepad combo

    I tested this on macOS 11.5.2 and confirmed both the "hold start" and "hold select" options worked for quit and for toggling the menu.

    Related Issues

    This is another way to address #2670.


    @jdgleaver was kind enough to inspire me in #12534 to contribute, so thanks to them, and maybe they can take a look as well.

  • [FEATURE REQUEST] Pause to Retroarch frontend when Bluetooth controller is empty

    [FEATURE REQUEST] Pause to Retroarch frontend when Bluetooth controller is empty

    This is something I have been wishing for some time. When a Bluetooth controller disconnects the game should pause to the Retroarch frontend. This is the default behavior of the PlayStation for example. I don't think that any special message from the controller like "I am dying" is required to implement this. Just enter the frontend when the connection is lost - may it be an empty battery or connectivity issues. I think this should also happen for any controller losing connection for fairness when being in a multiplayer session. Best would be only controllers that are actively being used in the current game, but I think that will be harder to detect.
