About the hacks i dont think you can find now maybe after 1 years you will find.
About the crosshair look this:
crosshair "1" //Display crosshair (1=enabled, 0=disabled)
cl_crosshairstyle "1" //Crosshair style (1=csgo, 2=classic static cs, 3=classic dynamic cs)
cl_crosshairusealpha "1" //Alpha on your crosshair (1=enabled, 0=disabled)
cl_crosshairalpha "200" //Alpha setting between 0-200 (0=transparent, 200=solid) - to work cl_crosshairusealpha "1"
cl_crosshaircolor "0" //Crosshair colour override (1=enabled, 0=disabled) - to work cl_crosshairstyle "2" or "3"
cl_crosshaircolor_b "0"//Amount of blue colour in your cross - to work cl_crosshaircolor "0"
cl_crosshaircolor_g "250" //Amount of green colour in your cross - to work cl_crosshaircolor "0"
cl_crosshaircolor_r "0" //Amount of red colour in your cross - to work cl_crosshaircolor "0"
cl_crosshairgap "0" //Increases the gap between crosshair and centre point
cl_scalecrosshair "1"
cl_crosshairscale "1"
cl_crosshairsize "5" //Increases the size of your crosshair
cl_crosshairthickness "1" //Increases the thickness of your crosshair
cl_crosshairdot "0" //Dot in the centre of your crosshair (1=enabled, 0=disabled)
cl_fixedcrosshairgap "3"
cl_observercrosshair "0" //Observer crosshair (removes the recoil scaling effects) (1=enabled, 0=disabled)
I prefer the normal crosshair from cs 1.6
Classic static no dynamic.
