These DLL files replace a couple files in your games folder. THEY WILL NOT AFFECT GAME PLAY IN ANY WAY AND WORK WITH ALL MODS. What they will do is report your games online status when you are hosting a "NovaWorld" game session to two alternate lobbies http://nw.novahq.net and http://novaworld.cc. These lobbies allow any player to join any game without the need to login or create an account on NovaWorld. These files DO NOT AFFECT anything else. Your game will still show up in the official lobby like normal.
These DLL files can also be used to create your own game lobby or server status for your website. PHP example scripts are included. You may use this information to display your server status or even create your own game lobby for your team to join through.
Download the archive, find your game version and replace the files in your games folder with the ones in the archive. It's super simple and automatic. There is nothing else to configure or install (but please read the *.ini file). You can use these files to host as many games as you want. You can view your games online status at the NovaHQ Alternate Lobby or Novaworld.cc Alternate Lobby
