I have just cracked the new version of Zoo Tycoon: Dinosaur Digs (11.5.0.7 (WinXP SP1))!
This is crack NOT for the new version of Zoo Tycoon (10.10.0.12 (WinXP SP1)), see 'zoo-xpsp1.zip' instead.
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 (http://www.microsoft.com/games/zootycoon/patch.asp) then patched by my cracker.
Please note only install the update (and my crack) if the following describes your situation:
"If you have recently purchased a new computer with Windows XP SP1 installed or you have done a clean installation (not an upgrade to your existing Windows XP installation) of Windows XP SP1 you may have encountered an issue wherein Zoo Tycoon or Dinosaur Digs will lock up when trying to play the intro movies. This patch will solve this problem."
Have fun!
