Serious answer, any number of people are capable and have the tools.
The one thing they most likely don't have is time. Even just the NES had some 1000+ games if you included variants, regional differences, and all the unlicensed stuff. You're asking for images of every cart, box, and manual? And we're not just an NES, or even a Nintendo forum. Sega, Playstation, Xbox? It's going to add up fast.
It would have to be a group effort, and someone would need to spearhead it. Asking someone else to do it is a good way for nothing to get done.
