Unless I'm wrong, just mounting the image on Daemon tools *doesn't* work with 1.3, same "please insert correct CD" message as 1.2 and 1.0 and such.
A crack for 1.3 would be the best thing, and long overdue for such a great game.
Edit: oh yeah, if anyone gets a crack made, give me an e-mail (with the crack perferably =)

Edit 2: Terribly sorry, I apologize
