So I don't really play many newer games, but I still want to play with friends online. Ive thought how awesome itd be to play some ps2 or n64 with a friend who's 500 miles away. But I cannot find anything that actually works (especially because I'm on Linux and theyre on windows)

Kind of surprised it doesn't exist because I'd pay decent money for that. Either one program that tunnels it for your specific emator, or specific emulators that have online built in...

And yes, I know its really hard to Implement this without lag. But people (nerds) are smart!

Edit: Clarification, I don't want to play games that had online or lan originally. I meant more games that are 2 or 4 player splitscreen play ,but online.
