I've tried to install de ES item unlock so that i could get the breeding center, i just can't win the Endangered Species challenge where you should create a 5-star Zoo!!
I have also tried to install the "Money Cheat Hack", but it just does not show up in the game...
I do it like this!
I first extract the files, then cut them out and goes to Documents and settings, den to Application data and on to the Map Microsoft Games, Zoo Tycoon 2, Downloads were i put in the files!
I have the Swedish version of the game, is that why the hacks doesn't work??
The i would be very happy if someone tried to create hacks that works on EVERY game, no matter what language!
