Np Nibelungen. To run it you need to change your server startup line, which only the server administrator can do. In the startup command line you just need to replace to game=ROEngine.ROTeamGame with game=ServGame.ServTeamGame.
This will only work with standard RO, not with an RO mods like DH or MN, or with any other game type. This is because there can only be one game type and they aren't compatible with each other unless one game extends from the other.
I don't believe you need to add anything to the .ini file. As you will have made ServGame the new game type, the server loads the file. I expect clients that connect will receive a download of the file too, as I expect the game type file is so critical that it will get added to the servers list of required files. But I can't test this right now as my wife is user her laptop that I need for a 2nd player connection - how dare she ! If I'm wrong and the file doesn't get downloaded to connecting clients then just add ServerPackages=ServGame to the server packages list in the .ini file.
