XInput controller autoconfig is built into the application, with other controller types available as external profiles.*Per-core and per-game configuration overrides*Built-in [https://docs.libretro.com/guides/crtswitchres/ <abbr title="On Windows OS you need CRT Emudriver OR EDID editor tool such as 'Custom Resolution Utility'.">Custom resolution/CRTSwitchRes</abbr>] and refresh rate for video output, with exclusive fullscreen mode and monitor index for multi-monitor setups.*Dynamic rate control for smooth audio and video, even when the game's output rate differs from your system's. Especially obvious with systems like GBA that do not run 60Hz.*Basic fast-forward, SRAM saving, savestate, etc. It supports serialization of the emulation state, which is used to provide real-time rewind and netplay.*[[Shaders and Filters|Pixel shaders]] and [[Shader_Presets|presets]], primarily using Slang, Cg and GLSL, with HLSL on Xbox 360. The shader format it uses is flexible and fairly easy to use, allowing for complex multi-pass effects with adjustable runtime parameters. Also supports traditional video filter plugins that are run in software.*Supports audio DSP filter plugins through .dsp configuration files.*Custom overlay support.*FFmpeg recording and playback support. It can record either the native resolution output of the core or the post-processed output of the frontend. Playback is handled through an internal FFmpeg libretro core.*Streaming support. By adding your twitch account to RetroArch and making some small [https://www.retroarch.com/index.php?page=recording setup], it is possible to stream on Twitch the content of the game played.*[[GGPO]]-like netplay (latency hiding rollback). It should be lag-free if everyone involved emulates at full speed, doesn't live on opposite sides of the world, and has decent internet speeds. It uses peer-to-peer UDP and supports two players. Due to rollback, it requires a fair amount of CPU power to run, and only works with cores that support serialization.*Options for decreasing input latency related to vsync by eliminating buffering by the video driver, as well as using frame delay to delay polling of inputs until right before a vsync occurs on the display.*Supports [[Input_lag|input lag-mitigating techniques]]. One of these setting is "Run-ahead" which allows cycle-accuracy emulators to run ahead of mandatory 1 or 2 frames of input lag. These settings allow emulators to [https://medium.com/@libretro/retroarch-1-7-2-achieving-better-latency-than-original-hardware-through-new-runahead-method-1b80d26bb5d1/ achieve better latency than original hardware] (Run-ahead option official debut in version 1.7.2).*[https://retroachievements.org/download.php#ralibretro RetroAchievements support].*Libretro cores compatible with [[BizHawk]] and [[Virtual_reality#VR_game_room_simulations|EmuVR]], so if you don't like using RetroArch as a [[Frontends|frontend]] you have other options as well.

*Custom resolution and refresh rate for output==Netplay==Netplay is now usable from the menu in current builds, under Settings>Netplay Options. You can get it to work with the [https://github.com/libretro/RetroArch/wiki/Using-command-line command line] or the long-deprecated [https://www.mediafire.com/download/yrydc78bl6y82z4/retroarch-phoenix.7z RetroArch-Phoenix Launcher] as well in older builds.

*Dynamic rate control for amazing sound even when itYou must specify whether you will be hosting (server) or joining (client) the game. If joining, you must also enter the host's run at a different rate than IP address in the videofield below. Make sure your firewall is open on port 55435 (default; you can change it if you like) and that the port is forwarded in your router, such as vsync causes sometimesif applicable. Especially obvious with GBAYou can also specify 'spectator mode,' which will allow an arbitrary number of spectators to join and watch you play without being able to play themselves.

For netplaySimilar to the GGPO platform, you must specify whether you will be hosting (RetroArch creates a constant stream of savestates which, along with button presses, are exchanged and compared between the server) or joining (and client) the gamemachines. If joiningthe savestates start to diverge, you must also enter the host's IP address game rolls back in time to a point where they both agree, and then the libretro cores emulates the field belowmissing frames all at once to get back to the appropriate spot. Make sure your firewall is open on port 55435 (default; you can change it if you like) and that This gives the port illusion of completely lagless inputs, which is forwarded in your router, if applicable. You can also specify 'spectator modeinvaluable for twitchy,' which will allow an arbitrary number of spectators to join and watch you play without being able to play themselvesfine controls.

Delay frames denotes the maximum number of frames RetroArch will need If you try to emulate at once connect to maintain synchronization due to actual network latency. You can figure out an appropriate ballpark for this number by pinging the other player a server and it immediately says client disconnected, open your log and dividing the time make sure your ROMs match exactly (in milliseconds) by 16 (roughly the number of milliseconds in it will complain about a frame from a game running at 60 fpshash mismatch otherwise). If the gameplay is it gives you a bit choppyweird time-out error, just close the window and try increasing to connect again, and it should work itself out (sometimes excessive spikes in network latency can cause the number of delay frames a bitstates to diverge catastrophically, resulting in this error).

Similar to the GGPO platform, RetroArch creates a constant stream ==Alternative Launchers and Frontends== There are plenty of savestates which, along with button presses, are exchanged and compared between the server and client machines. If the savestates start to diverge, the game rolls back in time to other frontends that can either work as a point where they both agree and then emulates the missing frames all at once to get back to the appropriate spot. This gives the illusion of completely lagless inputs, which is invaluable launcher for twitchy, fine controlsRetroArch or you can replace it entirely with another [[Frontends#Libretro|libretro frontend]].

==Controversies==A number of controversies have sparked during the development of RetroArch, mostly due to Squarepusher/TwinAphex's attitude and actions towards upstream emulators.
