For Safedisc 2 (up to 2,5) games I would take Safedisc 2 cleaner. You can find it here:

It's very easy. You only have to open the game exe and wait a minute.
Another unWrapper is Unsafedisc. First you have to know the exact version number of Safedisc. You can find it out with SafeDisc Analyser. For every kind of Safedisc you need another Unsafedisc Version. Then open with the correct Unsafedisc Dumper the game exe. A file will be created (originalfile.exe.data.bin) (There will come a message). Then Open this file with the correct rebuilder . Then it makes the crack (sdv2.testme.exe).
But UnSafedisc 2 is only up to Safedisc 2,4
You can find the Analyser and UnSafedisc at
