User blog:Danakun/Multiplayer wired LAN offline connection

I need help connecting to a local multiplayer match. I tried typing in the localhost thing in the IP and left the port at 7777. I just wanna be able to play with my younger sis cause she loves games like this but we don't have internet and cannot use himachi or whatever that thing is. If anyone could help it would be greatly appreciated. Any networking help to ensure we are connected would be appreciated also.
