How SF3 really works

I was wondering how does the SF3 CD test works…

The protection of games’ files takes place not in the factory, where the CDs are manufactured… but on the SF3 protection servers… so if really SF3 reads the physical structure of the CD how does it take the CD structure’s sample…

And second thing… The protection is supposed to read the times needed to read the specific sectors of the disc… But every DVD reader and writer have different seek times different read speeds… so the read times would differ on every optical drive… plus with time the drive is less accurate… that would mean that the games won’t run anymore…

There’s something strange about this… there must be something hidden on the CD… and the SF3 developers clouded ppl’s eyes with the physical structure shit…

I don’t know if I’m right or wrong… I’m just wandering… It would be great if someone experienced could explain how it works…

You get more feedback and info if you would have posted your question in the Optical Storage Technical Discussions forum.

@ work atm, so i have not too much time now, but:
this is the reason why starforce does check not only one passage of the disc but up to 4 passages. so it can calculate the relation for your drive between these passages…

This thread will be a good start.
