Corsair: In the event you can't make a 1:1 copy, do what I do and use Nero's or something like it...copy all files to your HD using windows explorer (or whatever you want), then add the No-CD fix (or patch) to the folder and burn it all.
Then install it and afterwards, rename the file you're fixing so you can keep it, and copy/paste your new file in it's place.
This way, you have a working copy AND you don't need the CD
I've got xxxx's of games like that and I NEED to do it due to the large volume of cd's I handle daily !
