G'day PSully
I understand Battlefield 1942 to be safedisc 2 protected (a clever protection to check if the user has the original CD)
In your case it sounds as though the backup copy you made is not a 1:1 copy. i.e. as you said it stays at the desktop & wont kick over into the game...... simply because the protection has not been able to pick it up as a 1:1 copy......
we could spend hours trying to help / advise you how to do it & then it depends on the Hardware your using as well, or simply (cause all you wanna do is play the damn game)
GO OVER HERE & download cdkillers (a regular helper of fixes to this site - thank him) Battlefield 1942-No CD + Mod fix.
Download all 4 parts & run part 1 first (you gotta have winrar installed) - the rest should be easy. Once youve installed the crack / fix you wont need CD2 to play the game.
When you tried it with the Original Disc Psully did it work ??
