From what i have learnt
clone cd is one of the few copiers that will copy microsoft games. If i have this right, most copy protection schemes work by writing "junk" sectors to a disk, sectors that cant be read by copying programs. Clone on the other hand doesnt seem to try and correct these errors, it just takes them as they are. Some games can have thousands of errors in the first thee % of the disk. In theory it is possible, on slower readers, that the read process can take as much as a day to complete. The new protection called safe disk 2 is even harder to copy, only certain burners have been capable of reproducing the protected disks. I know that there are several programs out there that can detect which protection scheme is being used and suggest what options to use with clone cd. Try Dividezero's site, he seem to have almost all you could need for copying just about anything!!
