Ok, I'll bite.
You have managed to "compile source codes" but yet you seem to think your issue with chat/npcs is fixable with a hex editor.
If anything, this would be an error in the server code rather than the client. But as you have "compiled it" you must understand this I'm sure....
You haven't given any evidences to prove any of this likely at all.
To put it simple, show some proof, how about a code extract for a recent addition, or how about the encryption Cypher.
As someone who has spent days reverse engineering the eudemons protocols, reading the old sources, inducing crashes at points in the client for the information needed to build my emulator, I can happily tell you, if you did indeed compile the client, your post would include something factual.
Do everyone a favor, and don't try acting like you have Something that isn't real, all it does is give false hope to everyone and gives you a reputation that will stick.
