This looks really impressive!

I wonder if this could snapshot the state of the game, use spare CPU capacity (including other cores) to simulate in the background and feed in various inputs, and try to give a preview of the upcoming map? It wouldn't have to get very far; trying a few common input patterns would suffice.

I also wonder if this could apply some heuristics to see if the sprite layer scrolls consistently with the background, and if so, provide a preview of upcoming sprites too. If they consistently spawn at the same point, render them at that point.
