Ai.obj of the second pack was last modified 03.12.2003. That's before both Prelude Live AND C1 according to this topic. L2Server.exe was also last modified before Prelude Live. I don't know what it mean but it has to mean something and to be honest I don't care if it's stripped C1 which I doubt. I tested it with proper Geodata of course and it works wonderful. Nothing else matters for me :)
