Consider the following similarities unique ONLY to these two copy-protection systems:
They both require a key to be extracted from a batch of CDs which is then entered by the user.
The key only works with original CDs.
You need a new key for each batch (Because the angle changes I think)
In Windows NT / 2000 / XP, Star-Force uses an auto-install driver.
We know that 98 / ME have Adaptec’s ASPI drivers, used for advanced CD reading.
NT / 2000 / XP don’t have these ASPI drivers, so to use their features, Star-Force would need to install them.
Somehow though, they have made it more effective because there aren’t as many problems as there were with CD-Cops.
Also, the same protection used by Star-Force Professional is used in Star-Force CDR. Physical angle checking can be used on both CDR’s and Pressed Silver CDs.
Also, there is a CDR version because unlike other protections, physical angle (CD-Cops style protection) checking would work on any CD Recorder regardless of what modes / options it supported.
Is Star-Force just CD-Cops, but more accurate?
