Yeah but you'll have to hunt for and fix the code wherever it is on every disk, which could be subtly or completely different between applications. "Recalculate track 9" is a simple program that would have worked on any Western Security DRM disk.
- Dylan16807 6y agoYou're assuming it's always in track 9 in the same spot. What if it isn't? And what if different applications use slightly different obfuscation? If we're assuming Western Security DRM is always in the same spot using the exact same method, why not compare it against some other type of copy protection that always puts the exact same checking code in the same spot? It would actually be easier to blot out the other type's code with NOPs than to recalculate obfuscated Western Security track-length tables.
