L2J client reverse engineering

[juki917]

There are some servers that use different packet encryption than stnadard L2J servers. When somebody wants to see plain packets, he need to know, how are packets deciphered on client. I would like to give it a shot and "see" real communication with server. My big problem is that i cannot override Themida protection of engine.dll, core.dll, and some other dlls. I can run debugger along with L2, but i cannot use any hardware breakpoints and stuff, cos themida detects it and crashes application. Does anybody manage to unpack at least engine.dll with correct EP and import table?
