Problem is that we dont know what to send, we need reverse-engineers.
uhm, that sounds pretty wired.
I mean if you doesnt know anythink about the packet encryption and stuff you shouldnt try to develope a Server Emulator.
If you know how the Packets are encrypted, just take a look at them.
If you know how the packets are build also its not that hard to find out wich packet is for what, but its very time consuming
If you dont know anythink about the Packets, good luck to find a dev / reverser who´ll do the work for you you will need it ;>
