Update: fixed! -connect command line argument broke.

In client/init.cs in the initClient function you have this small chunk of non-functional code:

// Start up the main menu... this is separated out into a
   // method for easier mod override.

   if ($JoinGameAddress !$= "") {
      loadMainMenu(); 
      connect($JoinGameAddress);
    }
    else

This don't work as there is no 'connect' function to be found anywhere (same with the torque example as well)

However,

if ($JoinGameAddress !$= "") {
      // If we are instantly connecting to an address, load the
      // main menu then attempt the connect.
      loadMainMenu();
      %conn = new RTSConnection(ServerConnection);
      %conn.setConnectArgs($pref::Player::Name);
      %conn.setJoinPassword($Client::Password);
      %conn.connect($JoinGameAddress);
   }
   else {

Gets this functional.
