SoulCalibur 3 just got a new option for netplay
So Arkadyzja just dropped it's PS2 netplay update. For those who don't know what it is, it's a emulator frontend/matchmaking client like Fightcade, but mainly used for PS1 and 4 player titles. It's still delay based as rollback is just not feasible, but it's as good as Dolphin netplay which is good enough to spectate and play NA East Coast to EU in my experience.
