For mounting iso's I tend to use deamon tools lite example of my simple bat file for a good old pc game Perimeter is "C:\Program Files (x86)\DAEMON Tools Lite\DTLite.exe" -unmount_all "C:\Program Files (x86)\DAEMON Tools Lite\DTLite.exe" -mount scsi, 0, "C:\crazybox\Roms\pc strategy\data\Perimeter_Gold\pgold.mdf" cd "C:\crazybox\Roms\pc strategy\data\Perimeter_Gold\game files\PGW\" perimeter.exe Hit a snag with a couple which require changing CD's but applied the same simple bats and used autohotkey to assign ctrl+alt+1 , 2, 3, etc to load each CD. Would your Method be better in the long run?
