I found that la2 client emu, but its not prepared even for Interlude, however i found there some very useful informations about structure :P
But how it works on CT2? Init packet got 186 bytes. So way that i get RSA key is : decrypt with BF, find key in packet? or xor also?:P And where exacly is this key alocate? In that client i can see its 12th byte, was that changed in CT2?
