Unicorn CPU emulator engine released

The project page is here http://www.unicorn-engine.org/

I think the project is fascinating. I wanted to build something similar, but unlike the authors of Unicorn I was doing everything from scratch.

The idea was that it would be a plugin for a debugger to aid dynamic analysis so that you could "execute" some piece of code(instructions) with the current values in real memory and registers and see what the end values will be and where the code will go/do. And then perhaps step-back and forth through the emulated code to see the execution in real-time. Made a mistake? Roll-back and change the emulated values see what jump or what result it gets.
