i think

ok i think that runescape is not fun i think some of you agree with me. but its good for hack reply and tell me what you think

Only hacks we have are Auto-It scripts, also known as bots. There are no other hacks without Java editing or Packet editing.

Adding on to Zacko7, there is no way of editing the runescape source, without being on the team.
You need access or somehow hack the dedicated host.
