In this post in a series on PC copy floppy protections, we take a look at XEMAG duplication's "Xelok" scheme.
Xelok was quite devious on the Apple II, implementing "fat tracks" that could not be produced with a conventional disk drive. However the PC doesn't allow such tricks, so Xelok appears a bit different on the PC platform.
We take a look at two titles that use it, Sargon III and The Ancient Art of War.
We also take note of a rather amusing bypass for this protection!
