I have been making new installers for several sierra games. You will need your original media to install them, but the installers will install the games directly from the CDs and set them up to run in DOSBox automatically from a Windows shortcut from the Start Menu or desktop. For CD games you only need the CD to install, not to play. I have a couple of floppy games supported, too. These you just need to copy the contents of the floppies to a folder on your harddrive and run the installer from the same folder. You can find them on the Sierra Help Pages here:
