I wanted to run an old computer game in Wine, that uses a 640x480 resolution on a touchscreen. This game wants to check the CD volume label, which regular loop mounting doesn't provide. But cdemu does!
I wrote a whole script to run the program after mounting the disc and setting the correct screen resolution.
