Easy... setup your command line to point to your emulator, having it read an image on D: (or drive of choice).. then in ALSO LAUNCH, plug in the first line of your image mounting tool of choice from above. Then in LAUNCH AFTER, you plug in the second line to unmount the image. Then when GameEx launches, it will execute the also launch and mount the image, then load up the emulator which begins reading from the "virtual" drive you just mounted, then when gaming is done, the emulator will close, gameex will launch the launch after, unmounting the disk, and return to the menu. If that doesn't work, swap the ALSO LAUNCH and COMMAND LINE codes.. Thereby the command line launches the mounting, and also launch launches the emulator. Seems pretty simple to me. Also, make sure your LAUNCH AFTER is actually configured like this: cmd /c "C:\Program Files\DAEMON Tools\daemon.exe" -unmount 0 Otherwise, it won't work. I've also noticed that that line is picked up by the Wizard's verify tool as non-existent. If you get that, just make a bat file with that line in it, and point gameex to the bat file for launch after instead.
