Going back to the original post, there are many ways to screw with Softice.
Frogsice is okay but somewhat outdated. It is useful however to log some of an apps methods to defeat sice.
Icedump does a pretty good job at defeating most of them, and if you rename vxds etc with icepatch then at least you have a fighting chance.
There is a good tut around by the main man R!SC which deals with Settlers3 (I think), and how to patch some types of sice detection "on the fly" so to speak. It's a good place to start.
These days many developers are adding heavy anti-debug stuff to prevent reversing of their software, and as mentioned earlier, there are those in the RE scene who keep their methods to themselves. This is not just out of selfishness, but more out of trying to keep the protectionists in the dark about which aspects of their art has been defeated.
In the end it's a rather a waste of time by these guys at Macrovision as cracks/patches appear very quickly after a game is released (and even sometimes before!).
And yes it is a good idea to read, read, and read some more, before installing and messing around with Sice. In the right hands it is extremely powerful, but in inexperienced hands it can cause you problems.
