I have just cracked the new version of Zoo Tycoon (10.10.0.9 12/20/2001 (Christmas Update))!
It removes the need to insert the cd when is game executed.
The new version zoo.exe must be downloaded via the zoo tycoon website or original game's auto update feature then patched by my cracker.
Have fun!
