1. You need a decompiler. For example dotNet Reflector

2. 9Dragons has 255 Keys which get decrypted with one and the same encryption sequence ( it varies on each server though)--> So 9Disciple catches the server packets decrypts them Modifies it and encrypts them and sends them back to server ( Saweet seems to know all Encryption Sequences for all servers (VN, TH, GER, US)

3. Almost verything will work if you have the right encryption sequence(if you exagerate it you'll get a DC though.

If you want to modify 9disciple exe file, forget it^^ Saweet has obfuscated it and the main part is inaccessible.... That's why I made the Topic (Open Source 9DiscipleTH).
