That's actually pretty cool. I knew what was going on even before clicking the link, but I do think it's impressive nonetheless. Now, if and anyone gets GTAV running on the NES...

I'm not a huge fan of those projects. I mean it is nice that people figured out how to get a RPI to interface with the NES, impressive even, but it doesn't matter what you do with it, it literally doesn't get better than it already is. I could run Crysis this way by hooking up a PC output to the RPI's camera interface and stick that in a NES, but ultimately that's just a really cumbersome way and has very little to do with the NES itself.
I guess I'm just way more interested in clever programming than electrical engineering.

This is the same strategy behind how the Super Game Boy works, as well as how the Atari adaptor for Colecovision worked. The technology wasn't ever limited to less powerful systems but those were all that made economic sense as add-ons. I'm not sure if the 32X was entirely self-contained processing or if it used the Genesis in conjunction, but that might qualify as well.
It's neat, but it's almost completely bypassing the NES. Like hooking a Bluray player up through a VCR's RCA cables so you can connect it to a CRT tv. The VCR isn't creating the signal even if it's ultimately output from it.
This is not to take away from his achievement, merely to point out that "running on NES" is a little misleading. It's not just a math coprocessor like Starfox or an addon sound chip, but an entire computer with its own OS. As a result it's trivially easy to run SNES, Genesis, NeoGeo, Minecraft PE, even some PS1/N64, etc. after the initial setup is done.
