It's claim that it can make a perfect copy of any protected game is a half-truth.
Copying the protections is dependant on what hardware you have also.
And then there's also copy protections like Tages that at the moment are not copyable.
My advice is to download
Clone CD (which does the same job as Blindwrite but in my opinion better), and
Clony XXL which will give you the correct settings to use in Clone CD.
Clone CD is also hardware dependent.
