 '''[[wikipedia:RetroArch|RetroArch]]''' (formerly '''SSNES''') is an open-source, multi-platform [[libretro]] [[Frontends|frontend ]] written in C or C++. It is designed to be fast, lightweight, and portable.

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.

*Streaming support.

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 the core must only works with cores that support serialization.

*Supports [[Input_lag|input lag-mitigating techniques]]. One of these setting is "Run-ahead to reduce latency.

It allows These settings allow emulators to [https://www.libretromedium.com/index.php@libretro/retroarch-1-7-2%E2%80%8A-%E2%80%8Aachievingachieving-better-latency-than-original-hardware-through-new-runahead-method-1b80d26bb5d1/ achieve better latency than original hardware] (Official 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.

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 [httphttps://www.mediafire.com/download/yrydc78bl6y82z4/retroarch-phoenix.7z RetroArch-Phoenix Launcher] as well in older builds.

Similar to the GGPO platform, RetroArch creates a constant stream 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 a point where they both agree , and then the libretro cores 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 for twitchy, fine controls.

If you try to connect to a server and it immediately says client disconnected, open your log and make sure your ROMs match exactly (it will complain about a hash mismatch otherwise). If it gives you a weird time-out error, just close the window and try to connect again , and it should work itself out (sometimes excessive spikes in network latency can cause the states to diverge catastrophically, resulting in this error).

===skeletonKey===There are plenty of other frontends that can either work as a launcher for RetroArch or you can replace it entirely with another [https://romjacket.github.io/index.html skeletonKey[Frontends#Libretro|libretro frontend]] is the successor to retroInvader. In addition to a simple netplay interface, nearly every aspect of retroarch can be set using this GUI.

===Phoenix=Also See==* [[EmulatorJS]]* [https://githubemulation.gametechwiki.com/team-phoenixindex.php/Phoenix Phoenix] is an alternative frontend for libretro that is independent of Category:RetroArch_PSP RetroArch, not to be confused with the discontinued RetroArch-Phoenix launcher. It is intended to mimic the style of [[OpenEmu]PSP], except using libretro and being available on Windows and Linux. It is still in early development and requires that you build it yourself through Qt, though the main developer says an alpha release with prebuilt binaries is on the way.
