Of course, that goes without saying. I meant it is the framework of all the earlier games machines/computers. In actual fact a modern Pentium class PC @ 3GHz struggles to do some of the things an Amiga could do (seamlessly anyway) due to extensive operating system issues (non-realtime) and the most expensive thing of all which is retargetable graphics. Early machines benefitted from the afct that everything was designed from the ground up for a particular screen size and depth.
Some of the arcade machines from around the mid 90's used clever hardware techniques to address CPU shortcomings of the time which are compute expensive in SW so there could be issues there as well.
Let's put it into the following frame of reference:
8-bit games machines.
For me personally those older games were a lot more enjoyable than a lot of the subversive reality games of today.
Well, it really depends onthe complexity of the emulator. Emulating old NES games isn't too difficult, however if you were to attempt to emulate an Xbox360, you'd find yourself getting nowhere. The last time I played with emulation a pretty strong computer struggled with Nintendo64 emulation. It has been a while though.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
