CDEMU/libmirage support both CCD et al and MDF/MDS images. Mixed modes, etc - the whole shebang. How good the copyright protection emulation is I cannot say tho.

I could be utterly wrong on this, but AFAIK the "emulation" in tools like Daemon Tools or Alcohol was only required when the disc image was created with partial or missing DPMS/subchannel data; If the virtual drive provides transparently the required stream the copy protection should be none the wiser on the actual drive emulation.

I'm by no means an expert on Starforce and friends, I'm just bringing attention to a nifty tool many I suspect aren't aware of. Also to highlight that CDEMU should support all these subchannel and stuff in CCD and others - maybe you right and this itself should make the protection algo happy, provided the image file is correct and comprehensive. It's just that I vaguely remember Cdemu had some specific protection options, but I might be wrong here.
