Packet Map

I was wondering if someone got a map of metin2's packets, or maybe some suggestion on how to understand how them work
I already managed to understand some of them, like the character list, but there are other that are driving me crazy.

Any help?

Download a Serverfile-Core and analyze the function CInputMain::Analyze() with IDA, that are the packets the client can send. I didn't found a function in the client that equals this server-function yet..

Cool, also I found some other infos about client packets in CPacketInfoCG::CPacketInfoCG()
But the real problem right now are the server packets, currently I'm stuck on understanding the one with id 0xFD. That opcode is used both for an handshake packet and for some sort of Login, it is sent on the entermap
