Before you begin, here's some things to consider:
;Before we begin;
* Emulator netplay is NOT perfect. Desynchs WILL occur very often. Choppy/stuttery gameplay is also very common, and sometimes there is controller input lag. It comes with the experience.
;*The term 'netplay' is occasionally used as a general descriptor for [[:Category:Online_gameplay|online play]], which is the subject of this page. This usage, however, may cause confusion for those unfamiliar with the term's nuances. It is essential to differentiate 'netplay' from the local multiplayer over internet functionality offered by some emulators, which was discussed in detail above.
* It sometimes takes several consecutive tries for the game to stay synched well enough to enjoy some multiplayer action. Do not be discouraged and try again until it works.
;*Port forwarding: You should note that some emulators and clients <u>may</u> require you to forward your ports. To do that, follow the [[Port forwarding guide for netplay]].
* When netplaying, make sure not to have anything downloading (torrents, Youtube videos, etc.)
* Try not to move the emulator window around, or switch focus to windows other than the chat/kaillera window and emulator, or you risk desynching the game.
* It's highly recommended to use a controller. Some emulators still register input from keyboards while you're chatting on separate chat windows.


==Port Forwarding==
==Methods for playing multiplayer games==
You have two options;
# [[#Local multiplayer]]
# [[#Online multiplayer emulation]]


Before you get started, you should note that some emulators and clients will require you to forward your ports. To do that, follow the [[Port Fowarding Guide For Netplay]].
===Local multiplayer===
==NES==
This section will cover consoles that originally supported local multiplayer, either through LAN connections or traditional couch co-op. Out of convenience, handheld consoles that required link cable or wireless within a small distance in the same room between two units will be considered local multiplayer as well.
===[[RetroArch#NetPlay|RetroArch]]===
*FCEU[http://wiki.libretro.com/index.php?title=FCEUmm], QuickNES[http://wiki.libretro.com/index.php?title=QuickNES], or [[Nestopia]][http://wiki.libretro.com/index.php?title=Nestopia] cores support netplay. Savestate cannot be used during NetPlay, and bringing up the menu screen will cause disconnection.


===[[VirtuaNES#NetPlay|VirtuaNES]]===
====Playing local multiplayer <u>over internet</u>====
===[[Mednafen#NetPlay|Mednafen]]===
You have three options for playing local multiplayer over internet;
*FCEU core
# [[#LAN tunneling programs]] - Needs to be supported by the emulator to support games that utilized the original system's local multiplayer functionality which the game utilizes.
# [[#Streaming programs]] - If emulated system had multiple controller ports for couch co-op and game supports it as well, you're all set...
# [[#Netplay]] - The emulator needs to implement Netplay to support games that utilized the original system's local multiplayer functionality which the game utilizes.


===[[Nestopia#NetPlay|Nestopia]]===
;Before diving in
===RockNESX 2.0===
First you need to know which consoles had local connection capabilities over via LAN or wireless technologies, this type is usually good with [[#LAN tunneling programs]];
*A very old NES emulator. Has a very nice interface but the documentation doesn't indicate what ports it uses, so you're limited to using a VPN like hamachi. The author did away with Netplay in more recent versions.
*[[:Category:Microsoft_consoles|System Link feature on Xbox consoles]]
===Jnes===
*[[:Category:Sony_consoles|LAN tunneling feature on PlayStation consoles]]
*Still shows signs of being updated, but it absolutely HATES anything other than stock Kaillera. I'm not sure if it's possible to get it to work.
*Local wireless connection using Ad-Hoc feature on PlayStation handhelds ([[PlayStation_Portable_emulators#Connectivity|PSP connectivity]], [[PlayStation_Vita_emulators#Communication|Vita communication]])
*[[Wii_U_emulators#Hardware_features_and_peripherals|LAN Tunneling feature on Wii U]]
*Local connection features on [[Nintendo_Switch_emulators#Connectivity|Switch]] and [[Nintendo_Switch_2_emulators#Connectivity|Switch 2]]
*[[GameCube_emulators|GameCube]] thanks to [[GameCube_emulators#Hardware_features_and_peripherals|Broadband Adapter]]


==SNES==
There are niche cases though, for example, some systems designed to use a proprietary wireless format that makes [[#LAN tunneling programs]] compatibility virtually impossible. The DS/3DS uses NiFi (Nintendo Wifi) which has no TCP layer unlike regular wifi. Because of this, it demands that incoming packets have to be received pretty much instantly, which is not really possible with online connection (Local connection over Internet),[https://www.reddit.com/r/MonsterHunter/comments/18z6mp/comment/c8jblo6/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button] because of this the 3DS/DS will just instantly disconnect you from the game. That is why the emulators usually has own solutions for this type of connections;
===[[RetroArch#NetPlay|RetroArch]]===
*[[Nintendo_DS_emulators#Hardware_features_and_accessories|Local Wireless connectivity and Download Play features on NDS]] (See [[Nintendo_DS_emulators#Connectivity|emulators own solution]] for this one)
*[[Snes9x]] or [[Higan|bsnes]] cores.
*[[Nintendo_3DS_emulators#Hardware_features|Download Play feature on 3DS]] (See [[#Netplay]] section for this one)
===[[Snes9x#NetPlay|Snes9k]]===


===[[Mednafen#NetPlay|Mednafen]]===
And then, most systems had either multiple controller ports for couch co-op or link cable support for local multiplayer/simple communication, this type is good for their convenience with [[#Streaming programs]] or [[#Netplay]];
*[[Higan|bsnes]] core
*Most systems
===[[ZSNES#NetPlay|ZSNES]]===
*[[Game_Boy_Advance_emulators#Hardware_features_and_accessories|Connectivity features on GBA]]
==Sega Consoles==


===[[KegaFusion#NetPlay|KegaFusion]]===
=====LAN tunneling programs=====
*Concerning Sega emulators, this is really the only one worthwhile option to netplay with. It emulates practically every single console and peripheral prior to the Saturn, all while allowing for some decent Netplay capabilities on the side.
These kind of programs usually creates/uses a network configuration that creates a virtual LAN connection and then allow systems to network with each other '''over the internet''' simulates connecting over LAN. This allows you to play games that support LAN multiplayer mode with others '''over the internet''', as if you were all on the same local network, replicating the fun of a [[Wikipedia:LAN_party|LAN party]] or [[Wikipedia:LAN_gaming_center|LAN gaming center]] but without needing to be in the same physical location. Some programs even offer additional features like lobbies and chat, further enhancing the online experience. LAN tunneling software isn't just for PC games, for example, XLink Kai supports lots of system if the system and game supports LAN/local connection. This means you can use some of these LAN tunneling programs for your consoles as well.
See [https://www.pcgamingwiki.com/wiki/List_of_games_with_LAN_multiplayer PCGamingWiki: List of games with LAN multiplayer on PC], or see [[:Category:Consoles|Consoles]] category for individual dedicated system pages to see LAN tunneling support and compatibility.

==Arcade==
=====Streaming programs=====
The many platforms that conform the term "Arcade" has got to be considered the most extensively researched and emulated platforms in existence. Choosing the right emulator is quite a daunting task, since there are so many different versions that accomplish the same thing in almost imperceptible different ways. Branching off from a standard official emulator that, by itself, is commonly regarded to leave much to be desired.
if the game supports local co-op option, you can use [[Netplay#Streaming_programs|streaming software]] for playing with your friends '''over the internet''' replicating the fun of a [[Wikipedia:Cooperative_video_game#Couch_co-op_and_online_co-op_modes|couch co-op experience]] but without needing to be in the same physical location.

===GGPO===
:[https://parsec.app/ Parsec] is a program to allow streaming local multiplayer games to others over the internet. Parsec only supports hosting from Windows or macOS. Windows, Mac, Linux, Android and web browsers can connect to Parsec hosts however.
* Arcade emulator built around netplay. Widely considered to have the best netcode for only multiplayer available. It's so great that its used in some more recent commercial games. Only disadvantage is that you need to open ports to use it, and it's severely limited to games that were made or modified specifically to use this technology.


* Built on the same emulator is FightCade which can be found here: http://www.fightcade.com/
:[https://store.steampowered.com/remoteplay/#together Steam Remote Play Together] can be used to allow games in Steam to be played with people through streaming. You can add emulators and any non-Steam games into your library by clicking "Games" from the title bar, and click "Add a non-Steam game to my library". Remote Play Together is supported on any device that can run Steam, and is the only option for hosting from Linux. Additionally, Android and iOS can connect to games via the Steam Chat app, making this the only option for iOS as a client.


===MameHUB===
:[https://github.com/LizardByte/Sunshine Sunshine] is self-hosted game stream host for [https://github.com/moonlight-stream Moonlight project] (formerly Limelight).
* Said to have a comparable netcode to GGPO, it's also capable of emulating console games through MESS. However, using MameHUB requires registration, and the frontend, being coded in Java, is an absolute resource-hog which heavily impairs your gaming experience if you're using a low-end computer. You can join a game that's already in session.  Newer versions of MAMEHub use much less resources.

[http://wiki.dolphin-emu.org/index.php?title=Netplay_Guide This guide should help], although it should be noted that netplay is not perfect. This is for playing with other Dolphin emulators.


For in-game WiFi...
=====Netplay=====
Netplay enhancement feature implementations for emulators and middleware such as [[GGPO]]; typically with the help of [[wikipedia:Netcode#Rollback|rollback networking]] technique, pure Peer-to-Peer connections or only use servers for matchmaking section, allowing for players across the globe to play the same game that has the local multiplayer capability as if they were in the same room. '''Emulator netplay is NOT perfect.''' Desyncs WILL occur very often. Choppy/stuttery gameplay is also very common, and sometimes there is controller [[input lag]], or even takes several consecutive tries for the game to stay synced well enough to enjoy some multiplayer action. This type of connection have potential to just instantly disconnect you from the game. You need to try again until it works. When using netplay, make sure not to have anything downloading (torrents, YouTube videos, etc.), try not to move the emulator window around, or switch focus to windows other than the chat/Kaillera window and emulator, or you risk desyncing the game. It's highly recommended to use a [[controllers|controller]]. Some emulators still register input from keyboards while you're chatting on separate chat windows.


Because Nintendo shut down it's servers for WiFi, it can't be connected to. Wiimmfi is the only option, but Dolphin will not be able to connect normally, as you require a normal Wii's files. [[How To Play Dolphin Online|This guide]] has instructions on how to get the certificates needed to connect to their servers, but do note, you cannot connect if you cannot run the game full speed. This also includes lag spikes that may occur. Your emulator will be banned from the servers if the game is unable to run full speed.

===Online multiplayer emulation===
{{Main|Preservation projects#Private platform servers}}
{{Main|Preservation projects#Private game servers}}
{{Main|:Category:Online services}}
Some consoles and systems offered during their lifetime options to connect to the internet (or similar services) to play against other people online.
 
While [[Preservation_projects#Private_platform_servers|most of these servers went defunct]], some of them are (or were) still up and the emulators were developed far enough to be able to interface with the actual official servers</abbr>. The others had [[Preservation_projects#Private_platform_servers|replacement servers]], that could host both real hardware players and PC emulator users. However in many cases emulator users were banned over cheating or concerns that emulation lag gave them unfair advantage (which is the case with Wiimfi's project, and some of its associated game mods that took it a step further to prevent the game from running on emulators).
 
Requirements '''may''' include:
 
* images of network certification files ripped from real hardware, which might be further complicated by the fact that the ones distributed online are much more likely to be banned. This is the case for Wii and Wii U online.
* if using custom servers, patching out the original URL addresses in the game to point at the newer servers instead. This is achieved either through Action Replay/Cheat codes, or modifying the game's image with dedicated tools.

* Because Nintendo shut down its servers for Wi-Fi, it can't be connected to. Wiimmfi is the only option, but [[Dolphin]] will not be able to connect normally, as you require a normal Wii's files. [[Dolphin Online|This guide]] has instructions on how to get the certificates needed to connect to their servers, but do note that you cannot connect if you cannot run the game full speed. This also includes lag spikes that may occur. Your emulator will be banned from the servers if the game is unable to run full speed. It's more recommended to connect via your Wii since you require files from it to play it on Dolphin, and it's risky to try with Dolphin regardless. CFG and USB Loader GX both support Wiimmfi without patching the game and do it on the fly. Looking into different custom servers than Wiimmfi is another option.
 
* [[DeSmuME]]: Main version 0.9.7 used to include an option to connect to Nintendo's own servers, and later, the custom servers. It works pretty well. However, since the project maintainers had ''creative differences'' and decided further development on it is to stop, it was never developed any further and as such existed for a long while as unofficial forks requiring an Ethernet connection (though further workarounds were found to enable any kind of connection). Very recently, it was added back in that state to the main builds.
 
* [[melonDS]]: A newer DS emulator by the developer who used to work on that feature. It has stable support for official [https://en.wikipedia.org/wiki/List_of_Nintendo_DS_Wi-Fi_Connection_games Nintendo WFC games] (see also [https://wiki.gbatemp.net/wiki/NDS_Multiplayer_Games this list]) when connecting to fan servers like Wiimmfi (see also [https://wiimmfi.de/stat?m=25 this list]). However, local wireless (NiFi) multiplayer over the internet (native netplay) remains unstable due to the DS hardware's zero-latency requirements. For these local wireless games, using [[Netplay#Streaming_programs|remote play]] software like Parsec to share a single-PC local play session is more reliable.
 
;Wii U and Nintendo 3DS

* See [[Nintendo 3DS emulators#Hardware features]].
 
* '''[[Cemu]]''': Supports online play pretty well, however custom servers are still not up so you'll have to risk your own Wii U's network certification files to use this feature. See [https://cemu.cfw.guide/online-play Cemu Online Play Official Guide].

* Sony online services for [[PlayStation_Vita_emulators#Hardware_features|PSV]], [[PlayStation_4_emulators#Hardware_features_and_peripherals|PS4]] and [[PlayStation Mobile|PSM]]: custom servers up for some games, nearly no emulation interest at the moment though (maybe other than [https://github.com/shadps4-emu/shadPS4/pulls?q=is%3Apr+is%3Aopen%2Bclosed+%5BLibs%5D+ PS4]). See those systems pages for more information about them.
* Horse betting service modem (NES, SNES), WonderSwan online (WSC), PS1 online (PS1/i-mode): zero interest, see [[Early online services]] page for more information.
 
==Methods for sharing single-player experiences online==
While memory card files, hard drive images, or save files for various emulators allows you to share your single-player game progress with your friends (sharing a controller on the couch <u>over internet</u>), it's far from a seamless process compared to sharing emulator's save states. Furthermore; for some systems, there are even more convenient solutions are available nowadays.
 
;Your Turn!: There is a new app called "Your Turn!" for simulating sharing a controller on the couch but over internet. This is different than [[#Playing local multiplayer over internet]] solutions, due to focusing on sharing a controller for singleplayer experience using emulator's save state enhancement.[https://old.reddit.com/r/emulation/comments/1ma3yn9/i_made_an_app_to_relive_the_your_turn_couch/]
<blockquote>How it works:
# You and your friend load the same ROM on the same emulator on your devices (Currently supported emulators for BETA: John GBA or John GBC - lite or otherwise)
# Open the Your Turn! app and invite your friend to start a game.
# Take your turn, save the game using the '''emulator’s save state''', add a note, and upload it in the app.
# Your friend gets a notification, reads your note, downloads your save, and plays their turn.
# Repeat back and forth - just like passing the controller! See [https://discord.gg/NZqKHpQAB2 their discord channel].</blockquote>
 
;[[#Streaming_programs|Streaming programs]]: Another option is using low-latency focused streaming programs for this.
 
==Scheduling gaming sessions==
[https://www.gamedate.org/ GameDate] is a public, anonymous platform for scheduling gaming sessions. It solves the discoverability problem for dead games, niche mods, retro netplay, and anything else that has players but no coordination mechanism.
No account required. No downloads. Just pick a game, set a time, and share.
