Currently using Kaillera is the only way to play n64 games online. I am the owner of one of the last two US active kaillera servers ("The Galaxy" - mainly for SSB) and I was wondering what the status of netplay is in Mupen64plus. We currently use an open source implementation of the kaillera protocol but having the netplay not integrated with the emulator makes lag, crashes, and desynchronizations very common. The main emulator people use online is an old version of Project64, but there is currently no open source emulator that has the capability of netplay. Moving off of kaillera to a better solution and an open source emulator would really be the only way to keep n64 online play alive.
