Hello, I know I'm terribly late to the topic, but I've achieved the 2012 and 2013 clients in my Novetus. 2013 is only working in a server, to play solo, you'll need to go on Novetus, press "Server" in the right down corner and then click on "Create Server" then after it opens you gotta click "Play", not "Play Solo" in the Novetus app, and you're running the 2013 app. For the 2012M one you can play solo or with a server.

2. Open it
3. Move everything inside the zip folder to the clients folder inside the Novetus folder.
