Ok, Runescape's server packets are encrypted, but that doesn't mean RS isn't written in java. Just as all data packets sent back to the server are encrypted. It just means you have to figure out the encryption. However, it would take quite a lot of know-how to even attempt that, plus the encryption is probably dynamic (meaning the encryption keeps changing). Hope that clears things up. Oh and do any of you remember the day that AutoRune was used to make tons of phats and even to kill the bankers in RSC? FYI: AutoRune is a program (long dead) used in RSC to edit server packets to spawn items, and even to kill bankers! To RoswellCrash: AutoRune was made in a few hours... not months. It just intercepted all packets being sent, you could then inject data into them and send to server.
