This software allows you to run your own region connected to VIRTUALIFE, providing you can host it. We use the official OpenSimulator server software, and have customised it for easy use on VIRTUALIFE.
Minimum requirements are (linux/mac/windows) .Net 6.x runtime.
First time Windows tutorial can be found here: OpenSim Tuto

This version will be needed for older .Net 4.6 and/or mono.
