Getting soooo much closer!!!!! I had to fix the syntax, the correct one is "path_to_dtlite.exe" -mount -0, "path_to_cue" This works, in that the disc image now mounts and the exe starts! Which is great! Butttttt (there's always a catch, right??)... Now I have a brand new issue. The exe starts, which begins with a menu screen that says "Play Game," "Install Game," "Remove Game," etc. If I pick "Play Game," that window "closes" and the actual game is supposed to then open... but it goes back to GameEx (with the game running in the background). So basically when I pick "Play Game," instead of keeping focus on the game, it returns to GameEx. New can of worms!
