Thanks for the reply! I'm using the Marble blast ultra pc port (from old marble vortex), and I'm not trying to use any of the online features. I was just wondering if it's possible to play multiplayer over a LAN (not-online) network.
I know it's possible, and I did watch tomysshadow's video about it, but I don't think any of my networks support port-forwarding. Kind of stuck at the moment
