News Smallest NES Contender Built Using Orange Pi Zero2

Granted it wouldn't really be affordable for small time production, but I always wondered what would it look like if we could make say an NES-on-a-chip or whatnot. I can't imagine the NES having more than say 100K transistors for the entire system. And given we can stuff billions of them on the footprint of a pinky even at 16nm...

Heck you could probably power the entire thing with a potato. Or at least a coin cell battery.
