Myst III Exile 4 disk version- no cd

[bobg4]

I have the 4 disk pc/mac version of Myst 3 Exile with all 4 disks loaded into the pc and want to avoid the constant exchange of disks. None of the myst no-cd software I have found seems to work. Can someone please point me in the right direction to obtain a no-cd exe file for the 4 disk version. Also I would like to make a backup copy and cannot seem to find a copy program that can handle the security on the disks. Any help would be greatly appreciated.
