Open “boot” in the \client folder (or “boot.cfg” if you have file extensions shown). If you want to play on a local server, download a server like 0.5.1 and extract all of the files before starting “LUNI Server.exe”. If you want to play on a public server, connect to the web interface, for example http://18.104.22.168/ for Jonny’s server, and register an account. Now with the boot file you opened, edit
AUTHSERVERIP=0:localhost, if you want to connect to a local server or
AUTHSERVERIP=0:(public server's IP), for connecting to a public server (for Jonny’s server,
AUTHSERVERIP=0:22.214.171.124). After this is done, all you have to do to play is run “legouniverse.exe” in the client folder.
