Someone on another thread mentioned that starforce 3 seems to use angular calculations to verify the disk. So it says that if I rotate the disk by X amount and read this far from the centre, the bytes returned should be XYZ... as I understand it anyway. Someone feel free to correct me.
When you copy the disk, the physical locations of sectors won't be a perfect copy. It's a tricky one to trick anyway, and means that programs like gamedrive and alcohol120% are immediately beaten.
For the most part, it's an extremely complete copy protection system. Encrypted instructions, debugger detection, advanced cd verification techniques. But nothing is immortal :-)
If I had the time, resources and knowledge, I'd attack the starforce driver itself and always get it to tell the client what it wants to hear. It'd provide a nice general crack for all sf3 games.
