While many games don't age well I'm confident a surprising number of games can be remastered into a playable state.

1) extract the art (including audio and other fixture data)

2) instrument some kind of parity-checker / validator against the base game

3) /loop to have an agent rebuild the entire game the way you want

The hard part is 2) and push comes to shove you could probably pay a part time high school intern to laboriously go through the game and make sure it is a faithful recreation.

IANAL, art assets are the IP of the creators. It would certainly be illegal to host or otherwise distribute the art assets you do not own. I see the industry coming down HARD on this form of reverse engineering if only because it is so easy.

EDIT: Shit, this is really going to incentivize game-streaming platforms (a la Google Stadia) and disincentivize gaming clients.

Game streaming is a massive loss leader (you can see this reflected in the increasingly slim per-month usage limits multiplied by the rising subscription prices), video at scale is far from a solved problem. Even with 8-12 simultaneous encodes per GPU (or iirc about double that from the accelerators) getting the density per rack to actually support the number of concurrent players required to approach being a commercial success is still very far away. This also ignores the very real logistical constraints decently routed bandwidth.
