CloneCD actually has an option of including a regular .cue file (CDRWin-style cuesheet) with the image it makes.
So whenever you encounter an image with four files instead of three (.ccd .img .sub and .cue), you can also disregard the .ccd and .sub file entirely, and just use the .cue and .img file like a regular raw-mode BIN/CUE set - the .img file doubles as a raw-mode .bin file, just with a different file extension.
