EmuLinker is a Kaillera network server. Kaillera is a client/server system that virtually any emulator can implement to enable network play, by mapping "Player 2" input to another user over the Internet using network communication. EmuLinker is a complete rewrite of the original Kaillera network server for the purpose of preventing exploitable bugs and adding features.
This is a port of the project from SourceForge to GitHub by the original author (Paul Cowan) on 6/25/2015. I am concurrently changing the license to GPL 2.0. No code has changed since 2006.
