While I could leave some drawn, annoyed explanation that we have a thread for this (Here if you want it,) I'll instead explain that there is no random netplay, you need an IP, be it a Hamachi IP or regular.

If you want to join a hamachi room for it, there's plenty around, but Hanzo Komeiji has one that's active, and does more then just IaMP, SWR, and 12.3.
