Done a backup of Outbreak like this…
Copied the files on the disk to a temp folder on the H/D
with the disk still in the cd-rom open up Nero and make a mixed mode cdrom.
Goto your Cdrom and the track files will be shown.
Drag the files accross from temp.
Drack the track files across
Get the no-cd patch from gamecopyworld
Drack that across too
Rename the new disk to Outbreak
Burn - install - replace the old outbreak file with new
Run and play
An old way to do it, but it works
You still need the cd in the drive to play single player games
