Hey and Welcome to CDF's!
Are you talking about DVD-ROM games here? The way SafeDisc works on DVD games is alot different to CD games. To the point where no bad sectors are used. The mini image principle still works. Insert the disk and fire up Alcohol 120%. Start the Image making wizard and allow it read up to 40/50mb. Mount this image and it should work. I tested this with BF2 (which uses SafeDisc 4.00.001) it works fine.
