Were you able to copy all files of cd 2 to the hard disk ? Write down the volume label too. You can now use Nero Burning Rom to make a compilation cd, just put those hard disk files in it, the same ways as on the original (same directories etc, same volume label). Then add a "Crack" directory to that compilation, and put the
links 2003 nocd in that directory, so you can copy it over the installed one after you install. If you have a cdrw, write it to that to test it, otherwise you'll have to risk making a coaster. After burning, test the new installation. If all goes well, the game will be installed and you will only have to copy that crack in the Crack directory to overwrite the same named file in the game directory on the hard disk, this is to disable the copy protection.
