Editing Netplay

This is a hub for various information about netplay. Most info was gathered from the guys over at /vr/, so if you have any questions or need someone to play retro games with, visit their [https://en.wikipedia.org/wiki/Irc IRC] channel at #/vr/_Netplay on [https://www.rizon.net/chat rizon.net] & and their official website [http://www.finalstarmen.net here]

==Getting Started==
Before you begin, here are some things to consider:
* Emulator netplay is NOT perfect. Desyncs WILL occur very often. Choppy/stuttery gameplay is also very common, and sometimes there is controller input lag. It comes with the experience.
* It sometimes takes several consecutive tries for the game to stay synced well enough to enjoy some multiplayer action. Do not be discouraged and 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 controller. Some emulators still register input from keyboards while you're chatting on separate chat windows.

===Port forwarding===
You should note that some emulators and clients will require you to forward your ports. To do that, follow the [[Port Forwarding Guide For Netplay]].

==Local Multiplayer Netplay==
This section will cover consoles that originally had '''local multiplayer''', also known as couch multiplayer, where multiple controllers were hooked to the same console. 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.

Netplay emulates local multiplayer allowing for players across the globe to play the same game as if they were in the same room. 
===Streaming programs===
=====Parsec=====
[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.

=====Steam Remote Play Together=====
[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.

Save states cannot be used during netplay, and bringing up the menu screen will cause disconnection.
* '''[[Mesen]]''': Mesen has a netplay feature, available by going to Tools -> Netplay. Hamachi (and other methods) or a port forward is required.

* '''[[RockNES|RockNESX 2.0]]:''' 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.
* '''[[Jnes]]''': 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.

=====Other=====
None of the existing emulators for the following Nintendo devices currently offer solutions for ''local multiplayer'' emulation through netplay. However, some of them have support for online gameplay modes that existed on the original console. Refer to the next section for more details.

* [[Nintendo DS emulators|Nintendo DS]]
* [[Wii U emulators|Wii U]]

===Sega Consoles===
=====Master System=====
* <span title="Check link for more information on netplay">[[Kega Fusion#NetPlay|Kega Fusion]] <sup>*</sup></span>: Besides RetroArch, this is really the only one worthwhile netplay option for systems older than the Saturn. It emulates practically every single console and peripheral prior to the Saturn, all while allowing for some decent netplay capabilities on the side.
* <span title="Check link for more information on netplay">[[Mednafen#NetPlay|Mednafen]] <sup>*</sup></span>: SMS Plus core
=====Genesis/Mega Drive & Peripherals=====
* <span title="Check link for more information on netplay">[[GENS#Netplay|GENS]] <sup>*</sup></span>: An acceptable alternative to Kega Fusion. While it only emulates [[Sega Genesis emulators|Genesis/Mega Drive]], Sega CD and 32X, it uses Kaillera for online multiplayer, which is helpful in case you get consistent desyncs while using Kega Fusion.
* <span title="Check link for more information on netplay">[[Mednafen#NetPlay|Mednafen]] <sup>*</sup></span>: Genesis Plus core is experimental but mostly functional; 2 players only.
* [https://www.fightcade.com/#download FightCade]: Supports Genesis games.
=====Saturn=====

=====Dreamcast=====
* [https://github.com/blueminder/flycast-dojo Flycast Dojo]: Netplay fork of [[Flycast]] supports Dreamcast games. Also featured in [[FightCade]] for NAOMI & Atomiswave emulation.

=====PlayStation 2=====
* '''[[PCSX2]]''' ([http://www.mediafire.com/?r3c1ejv5m85ekrv unofficial netplay build]): Netplay has never officially been added to PCSX2, but someone tried making their own branch a few years ago to implement it. Only about seven fighting games work, and the project has since been abandoned.

=====PSP=====
PPSSPP and JPCSP supports multiplayer on the same network but only the JPCSP supports XLink Kai. See [[PlayStation_Portable_emulators#Hardware_features|this section]] for more information.

=====Other=====
None of the existing emulators for the following Sony devices currently offer solutions for ''local multiplayer'' emulation through netplay.

* [[PocketStation emulators|PocketStation]]
* [[PlayStation 3 emulators|PlayStation 3]]
* [[PlayStation 4 emulators|PlayStation 4]]<!-- (NOT emulated) -->
* [[PlayStation Vita emulators|PlayStation Vita]]

===Arcade===
The many platforms that conform to the term "arcade" have 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 imperceptibly different ways. Branching off from a standard official emulator that, by itself, is commonly regarded to leave much to be desired.

* [[FightCade]]: A matchmaking platform bundled with different arcade and home console emulators with P2P online play. Core multi-arcade emulator based off of [[FinalBurn Neo]] with a custom implementation of [[GGPO]] for rollback netplay. Also has support for NAOMI and Atomiswave games via <span title="Check link for more information on netplay">[[Flycast#Netplay|Flycast]] <sup>*</sup></span> with delay-based netcode.
* [[GGPO]]: [[Arcade emulators|Arcade emulator]] built around netplay. Pioneered rollback netplay, widely considered to have the best multiplayer netcode available. It's so great that its used in some more recent commercial games. The 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. Originally built on the same emulator as FightCade, [[FinalBurn Alpha]].
* [https://github.com/RossenX/NullDC-BEAR NullDC BEAR]: A Serverless, self-contained package for online Retro Games, Supports: Naomi, Dreamcast, Atomiswave via custom build of [[NullDC]]. NES, SNES, PSX, Sega Saturn, Sega Megadrive, Gameboy Advance, Gameboy Color, Neo-Geo Pocket via [[Mednafen]].
* [https://github.com/MisterTea/MAMEHub MameHUB]: 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, is 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 fewer resources.

==Online Multiplayer Emulation==
This refers to different game modes than regular local multiplayer. Some consoles offered during their lifetime options to connect to the internet (or similar services) to play against other people online. 

While 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. The others had 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 codes, or modifying the game's image with dedicated tools.

===Sony Consoles===
=====PlayStation 2=====
* '''[[PCSX2]]:''' Has an option to connect to Sony's own servers (or replacement servers) provided the game is still up. Relevant links: [[How To Play PCSX2 Online]] (See [[Online PS2 games]] for what games still have servers up)

=====PSP=====

2.Change DNS for non CFW
3.Use the Xlink kai to Lan

===Nintendo Consoles===
=====Wii=====
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.

=====Wii U=====
* '''[[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.

=====Nintendo DS=====
* [[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, is planning online support.

===Sega Consoles===
=====Dreamcast=====
* [[Flycast]]: Auto-configured to connect to [https://dreamcastlive.net/ Dreamcast Live] servers for games that are supported. Also supports networking for NAOMI arcade games.
When trying to hit "Homepage" in game, ocasionaly crashes the emulator, but some games like PSOv1, Samba de Amigo and first revision of Jet Grind Radio are crashing only when exiting the 
browser.
Planetweb browsers get stuck while loading pages.

===Other===
Status of various other consoles and their emulation of online features:

* Satellaview (SNES): Custom broadcasts already can be emulated on bsnes-plus, still WIP.
* XBAND (Genesis/SNES/Saturn): SNES XBAND emulation revival WIP.
* GB Online Adapter (GBC/GBA): WIP.
* Phantasy Star Online (DC/GC/PC): Custom servers already up, emulation WIP.
* [[Android emulators|Android]]: Emulators can already connect online.

Inactive online feature development:

* 3DS Nintendo Network (3DS): no interest from Citra developers.
* Sony online services (PSP/PSV/PS3/PS4): custom servers up for some games, zero emulation interest.
* Horse betting service modem (NES, SNES), WonderSwan online (WSC), PS1 online (PS1/i-mode): zero interest.
