The actual cheats, AimTux, Fuzion etc. (forks of AimTux) all have been sigged by Valve's anti cheat. It is recommended to make your own paste or edit the current source code to receive a new signature.
I suggest checking out Coldpatcher if you want a nice meme.
With that said, Hotpatcher reached its end of life. Support will no longer be given.
