Here is a server emulator, just copy cfye_epvp_loco.exe into your bjx directory and run it instead of CFYE.exe.
You might wanna delete CFYE.exe so that you don't accidently execute it in future.
Finally figured how gamecard server handshake works.
It sends your password to the bjx server, the server returns your encrypted password, and this encrypted password is being sent in the login packet to the Conquer Online server.
This was probably done in order to make cracking it pretty hard as you would need extensive knowledge on how Conquer Online login procedure works.
Your firewall might still give you a warning that it is trying to connect to the BJX server as I didn't hook the connects, but you can ignore this as all packets that contain login/password/server won't leave your computer.
Edit: To be exact, no packet will be sent to the BJX server.
