    Need help Reverse engineering game king of kings 3

    Need help Reverse engineering game king of kings 3
    So their is this game called king of kings 3 servers where shut down a while ago only game files are left i am wondering what would be needed to start a private server for this game only with game files. A chinese version of the game is still up and going but alot of things have changed still maybe would be more easy to get a private server running from the chinese version and then convert it to english since they are the only ones who have a running server of the game.

    All knowledge/help would be appreciated.

    It was a long time since I looked at this game, I gave up on it since the server was leaked, but in what I remember you can easily backtrace from the send method to the encryption, which is a XOR. Also the client on connection receives from the server the seed key before sending login details.

    Heya, any idea exactly where these functions are? Tried finding it but cannot seem to find it, probably blind as usual. And any idea from what the seed key is generated?

    Backtrace the winsock.dll. This dll is responsible for the send() and recv() functions. Usually the send() is called after the encryption was made and recv() is called before decoding the packet. Is possible that the key is not the same for all the data. If you have luck, there's only 1 key for all the packets. Try using a packet sniffer like SocketSniff and see how the packet looks like, this way you can determine the packet length and the header of the packet(the command) and the data. Most of the game have: first 2 bytes packet length, next 2 bytes header and the rest of the packet is the data. It's a lot of trial and error... I recommand IDA Pro for such things(this is what I'm using) but if you are more comfortable using other debuggers, it's fine with those too.

    If you have 100 years to live, it will take a little more than 300 years.

    And for fuck's sake, please have your system locale change to Chinese PRC if you ever getting or sharing the files from chinese games
