RetroArch is a front end for various emulators ported over to the [[libRetro]] library. Each core is a specific emulator, for a specific set of hardware. While not the actual emulator, its become a common theme amongst people to say they run RetroArch to play their games, instead of the actual emulators in [[libRetro]].

RetroArch runs programs converted into dynamic libraries called libretro cores, using several [[user interface]]s such as command-line interface, a few [[graphical user interface]]s (GUI) optimized for [[gamepad]]s (the most famous one being called XMB, a clone of Sony's [[XrossMediaBar|XMB]]), several input, audio and video drivers, plus other sophisticated features like dynamic rate control, audio filters, multi-pass [[shader]]s, [[netplay]], gameplay rewinding, cheats etc.

RetroArch has been ported to many platforms. It can run on several PC operating systems ([[Microsoft Windows|Windows]], [[OS X]], [[GNU/Linux]]), home consoles ([[PlayStation 3]], [[Xbox 360]], [[Wii U]], etc.), handheld consoles ([[PlayStation Vita]], [[New Nintendo 3DS|Nintendo 3DS]], etc.), on smartphones ([[Android (operating system)|Android]], [[iOS]], etc.), embedded systems ([[Raspberry Pi]], [[ODROID]], etc.) and even on web browsers by using the [[Emscripten]] compiler.

 +
== History ==
 +
Formerly known as SSNES, initially based on pseudonymous programmer [[higan (emulator)|byuu]]'s ''libretro'' predecessor ''libsnes'', it began its development in 2010 with Hans-Kristian "themaister" Arntzen committing the first change on [[GitHub]]. It was intended as a replacement to [[Higan (emulator)|bsnes]]'s [[Qt (software)|Qt]]-based interface but it grew to support more emulation "cores". On April 21, 2012, SSNES was officially renamed to RetroArch to reflect this change in direction.
 +
 
 +
RetroArch's version 1.0.0.0 was released on January 11, 2014 and at the time was available on 7 distinct platforms.
 +
 
 +
On February 16, 2016, RetroArch became one of the first ever applications to implement support for the [[Vulkan (API)|Vulkan]] graphics API, having done so on the same day of the API's official release day.
 +
 
 +
On November 27, 2016, the Libretro Team announced that, alongside [http://www.lakka.tv Lakka] ([[OpenELEC|LibreELEC]]-based RetroArch [[operating system]]), RetroArch would be on the [[Patreon]] crowdfunding platform to allow providing bounties for developers who fix specific [[software bug]]s and to cover the costs for [[Matchmaking (video games)|matchmaking]] servers.
 +
 
 +
On December, 2016, GoGames – a company contracted by video game developer and publisher [[Sega]] – approached the RetroArch developers with the intention of using their software in their SEGA Forever project but ultimately the cooperation did not come to fruition due to licensing disagreements.
 +
 
 +
In April 2018 Input Lag Compensation was added.
 +
 
 +
== Features ==
 +
Its major features include:
 +
* Advanced GPU [[shader]] support - A multi-pass post-processing shader [[Pipeline (computing)|pipeline]] allows efficient use of [[image scaling]] algorithms, emulation of complex [[CRT display|CRT]], [[NTSC]] video artifacts and other effects;
 +
* [https://github.com/libretro/libretro.github.com/raw/master/documents/ratecontrol.pdf Dynamic Rate Control] to synchronize video and audio while smoothing out timing imperfections;
 +
* [[FFmpeg]] recording - Built-in support for [[lossless]] video recording using FFmpeg's [[libavcodec]];
 +
* Gamepad [[abstraction layer]] called Retropad;
 +
* [[Gamepad]] auto-configuration - Zero-configuration needed from the user after plugging a gamepad in;
 +
* [[Peer-to-peer]] [[netplay]] that uses a [[rollback]] technique similar to [[GGPO]];
 +
* Audio [[Digital signal processor|DSP]] plugins like an [[Equalization (audio)|equalizer]], reverb and other effects;
 +
* Advanced savestate features - Automatic savestate loading, disabling SRAM overwritting, etc.;
 +
* Frame-by-frame gameplay rewinding at the press of a button;
 +
* Button overlays for [[touchscreen]] devices like smartphones;
 +
* [[Thumbnail]]s of game [[Video game packaging|boxarts]];
 +
* Low input and audio lag options;
 +
* Automatically build categorized playlists by scanning directories for games/ROMs;
 +
* Multiple interfaces including: [[Command-line interface|CLI]], XMB (optimized for [[gamepad]]s), GLUI/MaterialUI (optimized for touch devices) and RGUI (available everywhere);
 +
* [[ROM image|Game ROM]] scanner - Automatically constructs [[playlist]]s by comparing the [[Hash function|hashsums]] of a [[Directory (computing)|directory]]'s files against databases of hashsums of known good game copies.
 +
* Libretro [[database]] of cores, games, cheats, etc.
 +
* [[OpenGL]] and [[Vulkan API]] support.

RetroArch is the reference implementation of the libretro API. It is free, open-source, cross-platform software, licensed under the GNU GPLv3.

It is described as a front-end for emulators, game engines, video games, media players and other applications, designed to be fast, lightweight, portable and without dependencies.

RetroArch runs programs converted into dynamic libraries called libretro cores, using several user interfaces such as command-line interface, a few graphical user interfaces (GUI) optimized for gamepads (the most famous one being called XMB, a clone of Sony's XMB), several input, audio and video drivers, plus other sophisticated features like dynamic rate control, audio filters, multi-pass shaders, netplay, gameplay rewinding, cheats etc.

RetroArch has been ported to many platforms. It can run on several PC operating systems (Windows, OS X, GNU/Linux), home consoles (PlayStation 3, Xbox 360, Wii U, etc.), handheld consoles (PlayStation Vita, Nintendo 3DS, etc.), on smartphones (Android, iOS, etc.), embedded systems (Raspberry Pi, ODROID, etc.) and even on web browsers by using the Emscripten compiler.

History[edit]

Formerly known as SSNES, initially based on pseudonymous programmer byuu's libretro predecessor libsnes, it began its development in 2010 with Hans-Kristian "themaister" Arntzen committing the first change on GitHub. It was intended as a replacement to bsnes's Qt-based interface but it grew to support more emulation "cores". On April 21, 2012, SSNES was officially renamed to RetroArch to reflect this change in direction.

RetroArch's version 1.0.0.0 was released on January 11, 2014 and at the time was available on 7 distinct platforms.

On February 16, 2016, RetroArch became one of the first ever applications to implement support for the Vulkan graphics API, having done so on the same day of the API's official release day.

On November 27, 2016, the Libretro Team announced that, alongside Lakka (LibreELEC-based RetroArch operating system), RetroArch would be on the Patreon crowdfunding platform to allow providing bounties for developers who fix specific software bugs and to cover the costs for matchmaking servers.

On December, 2016, GoGames – a company contracted by video game developer and publisher Sega – approached the RetroArch developers with the intention of using their software in their SEGA Forever project but ultimately the cooperation did not come to fruition due to licensing disagreements.

In April 2018 Input Lag Compensation was added.

Features[edit]

Its major features include:

  • Advanced GPU shader support - A multi-pass post-processing shader pipeline allows efficient use of image scaling algorithms, emulation of complex CRT, NTSC video artifacts and other effects;
  • Dynamic Rate Control to synchronize video and audio while smoothing out timing imperfections;
  • FFmpeg recording - Built-in support for lossless video recording using FFmpeg's libavcodec;
  • Gamepad abstraction layer called Retropad;
  • Gamepad auto-configuration - Zero-configuration needed from the user after plugging a gamepad in;
  • Peer-to-peer netplay that uses a rollback technique similar to GGPO;
  • Audio DSP plugins like an equalizer, reverb and other effects;
  • Advanced savestate features - Automatic savestate loading, disabling SRAM overwritting, etc.;
  • Frame-by-frame gameplay rewinding at the press of a button;
  • Button overlays for touchscreen devices like smartphones;
  • Thumbnails of game boxarts;
  • Low input and audio lag options;
  • Automatically build categorized playlists by scanning directories for games/ROMs;
  • Multiple interfaces including: CLI, XMB (optimized for gamepads), GLUI/MaterialUI (optimized for touch devices) and RGUI (available everywhere);
  • Game ROM scanner - Automatically constructs playlists by comparing the hashsums of a directory's files against databases of hashsums of known good game copies.
  • Libretro database of cores, games, cheats, etc.
  • OpenGL and Vulkan API support.
