I premise that lfsanus is an old and experimental tool I wrote for testing the quick (and almost blind since I didn't spend many time identifying all the fields of the packets) modification of the packets of Live for Speed for creating that funny video on youtube: http://www.youtube.com/watch?v=MDK5EVX6z7Y
So I don't know if the tool still work with the latest Z patch.
And remember that YOU will NOT see the effects, ONLY the other people on the server will see them (in fact the video on youtube has been recorded from another client in my same server)
For using it it's enough to launch it and specifying the server to which you want to connect.
then launch your LFS client and join the server 127.0.0.1
when your client has joined, return on the lfsanus tool and press the needed number plus RETURN, for example 14 activates the flying of the car (when you hit the horn the other clients will see your car going upper in the sky) and so on.
Anyway I repeat, it's only a funny test tool.
