Changes

* [https://www.fightcade.com/#download FightCade]: Is on an experimental NES rollback-based netplay test with just one game, Contra, but the Fightcade team is looking forward to support more than just that in the future.experimental

* [https://www.fightcade.com/#download FightCade]: Preliminary supportSNES rollback netplay, it's very unstable for now.experimental

====Sega Consoles========Master System=====* <span title="Check link for more information on netplay">[[Kega Fusion#NetPlay|Kega Fusion]] ^*</span>: Besides RetroArch, this is really the only one worthwhile netplay option to netplay withfor 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]] ^*</span>: SMS Plus core=====Genesis/Mega Drive & Peripherals=====* <span title="Check link for more information on netplay">[[GENS#Netplay|GENS]] ^*</span>: An acceptable alternativeto 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]] ^*</span>: Genesis Plus core is experimental but mostly functional; 2 players only. Also has a Master System core.

* [https://www.fightcade.com/#download [FightCade]]: A software client used to enable networked multiplayer play of various matchmaking platform bundled with different arcade and home console (Probably 2D graphics only) systems via emulationemulators with P2P online play. It is Core multi-arcade emulator based off the then-inactive of [[FinalBurn AlphaNeo]] with a custom implementation of [[GGPO]] but also for rollback netplay. Also has support for NAOMI and Atomiswave games via <span title="Check link for more information on netplay">[[NullDCFlycast#Netplay|Flycast]], though this is not rollback based but ^*</span> with delay -basednetcode.* '''[[GGPO]]:''' [[Arcade emulators|Arcade emulator]] built around netplay. Widely Pioneered rollback netplay, widely considered to have the best multiplayer netcode for only multiplayer 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. Built Originally built on the same emulator is '''as FightCade''', which can be found [https://www.fightcade.com/ here[FinalBurn Alpha]].* [https://github.com/RossenX/NullDC-BEAR NullDC BEAR]: Online 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.

* [https://www.fightcade.com/#download [FightCade]]: Supports only Hu-Card games.

* '''[[Cemu]] supports ''': 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.

* [[DeSmuME]] main : 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 : A newer DS emulator by the developer who used to work on that feature, is planning online support.
