Okay.. then I feel like I should start worrying. I only have the x100 file. I did a full My computer search for the other and turned up nothing. I have all my hidden files shown.
I'm beginning to wonder about my copy of the game, then. I bought it at Target, but I had to install twice. The first install, all my animals were steadily getting angry despite having all needs met. After the second install, of the whole game, including original zt2, it started working.
However, now that I cannot find this file, I don't know. Maybe my copy is busted...
