I'm not new to MMO Server Emulation, but I am new to working with a protected Client, and have very basic RCE skills. I would appreciate some direction, and maybe this won't be possible, given the requirements.
The target is Uncharted Waters Online, now published by Papaya Play, utilizing GameGuard (instead of X-Trap, as the previous publisher).
- Prevent the Client from loading or attempting to refer to GameGuard.
- Understand the client-server communication through Packet Analysis. Obviously, impossible with Encrypted Packets.
How entrenched is GameGuard? Will simply bypassing the loading routines be enough?? Or must I allow it to load, but Bypass all the functions that it alters? Obviously, I would like the Client to not have to load GameGuard when accessing the Emulated Server.
Encrypted Packets. A major task will be to see the unencrypted packet contents while connected to Live Servers. Does anyone have experience with this? My thoughts are to find and detour the encryption and decryption functions, to output the raw packet information somewhere else. Is this a viable approach? Is this practical, or is there an easier way for me to understand the network communication?
Thanks all. All I'm looking for is an approach. I can research on my own how to achieve that, but at this point, I don't know enough about GameGuard and Reversing Packet Encryption to know where to start.
