Option to disable automatic emulation.

As mentioned above i can confirm that Safedisc emulation is active, but not SecuROM & RMPS (haven't tested Laserlock).

The defective sectors are not the weak sectors. First are the weak sectors and after those the defective ones. You can check that e.g. in Alcohol's Sector Viewer.

Safedisc emulation in fact emulates bad sectors only
on CD-R/CD-RW and can work only for very old games.
It does not emulate any weak sectors on newer Safedisc games. So it has no much sense to enable it now - it is already obsolete long ago.
For images emulation is not needed at all as they have perfect weak and bad sectors and game can work without any emulation.
If you need to emulate weak sectors on CD-R/RW or DVD-R/RW media then you need burn Safedisc image with RMPS option in Alcohol and it will do the job.

Don't cooked images have zeroes (or with more adequate programs consecutive 55h) in place of bad sectors ?

My Grand Prix 3.iso (SD 1.5) doesn't work mounted in older versions of DT (or e.g. the current Alcohol version) - only working with Safedisc emulation active.

Or did you simply mean a "good image" when saying that emulation isn't needed ?

DT PRO grabber creates table of bad sectors inside MDS even for cooked images, hence they are automatically generated by virtual drive. That is why it works without emulation.
Older cooked images which which have no bad sectors in MDS may need emulation though as you say.

Yeah, it's nice how the grabbers only suck up the essentials

DT Lite 4.35 and DT Pro 4.36.0309 - still the same trouble.
Mds/mdf w/o bad/weak sectors (tested with cdmage). SD 1.41. With Alcohol52% FE 2.0.1 and SD emulation off the game says "insert correct cd". If sd emulation turned on - game play w/o questions.
With DT - even if safedisk emulation disabled - protection still passed through.
Please, remove this auto-emulation...

I guess (personal opinion) it will not happen as then for image emulation options must be enabled and then problems can happen with burning disks.

If you enabled SD emulation in Alcohol then setting in DT does not matter then - SD emulation is enabled globally for all CDROMs in system if at least one program enables it. Behavior of Alcohol and DT is same.
