One could replicate the NES hardware without any knowledge of how it was built by reverse engineering it

I actually agree but in the same way that you have a "new mind" when you wake up in the morning. The continuity of self is an illusion. "I" would be very happy to one day wake up having been transferred into a non-biological system the same way that "I" would be very happy to wake up tomorrow.
