Mods, I'm not sure if this is allowed, so delete the topic if it's not (but don't ban me!)

I'm not asking for images or anything, but i noticed someone here mentioning SFA3 and MvsC online with kaillera and I was curious as to how? Can someone explain it to me or give me a link?

Thanks boys!
CPS-2 Emulator. Kawaks is a great one. It has a Kaillera client built in. There are other emus, but Kawaks is the one I prefer.
Just use the one with lowest ping. It really depends on your location in the world. Also use MAME not kawaks because mame supports cps-2 as well as old school and neogeo games.
