I saw a talk where a guy was showing how to cheat at some games. A lot of games will detect and crash you out if they detect a debugger attached to them.<p>Things like Punk Buster, et. al. are more like anti-virus software: they try to find the signatures of known chat clients.<p>So it&#x27;s best to write you own...and rename your debugging process to &quot;Google Chrome.&quot; He got pretty far with his auto-walker in some MMOs. He had limiters so his runs wouldn&#x27;t be too fast and would go up&#x2F;downhill correctly...or so he though. He forgot to multiple by -1 somewhere and the server banned him for attempting to fly of into space.
