Lol you are guys funny...
You don't need anything. Pick 7.7 (not 7.72 or 7.1) version in the blackd settings -> set as an OT server this address: s.the-realots.net and port 7170 (obviously you would need to point blackd to the directory with realots files).
Voila! You've got your blackd working.
btw. any 7.7 bot will work since this version is used as an "antibot" client with fancy image changed xD and all addresses are the same - don't believe - use cheat engine and check yourself
