Crossfire hacks and sim

I have been looking for working crossfire hacks for time now and have had no joy in finding any thing.

If anybody knows where to get working hacks i would be most grateful.

So in other words GIVE ME HACKS OR I KILL THE MONKEY

Also i have been looking for things you can do to your computer which give you an advantage but it isn't really a hack.
Like turning your Gamma up or turing on magnifier on your crosshears

Is there any way i could layer crosshears on my screen?

Thanks again
