Run DS1 and 2 Mod Execs without the CD

I usually run DS and DS2 with the Mod execs. You need the CD to run the Mod exec.s. *** (Not True)*** The problem here is if your CD's are old, a bit scratched, and well used, you really want just put them away in a secure place and not have to use them anymore.
So what I did, in order to preserve the discs was to make ISO Copys. If you make it right, the ISO Copy will be excepted by the game, just as if you are using the CD.
In fact, it's a good idea to make ISO Backups of every game disc you are concerned about. I've given a link for the program I use, but it's been so long since I used it, I can't give any direction, you will just have to play with it. This program, " ISO ToolKit " (freeware), only works for CDs, not Dvds. I probably used Alcohol 120% to do the Broken World DVD.
