Something incredibly similar is already built into the latest versions of Snes9x.

hq4x and the #xBRZ algorithms are amazing and fast and look nearly identical to these results.

They compare it to hq4x in their supplementary materials. Theirs is better.

hq4x looks a lot better in the video comparison: http://johanneskopf.de/publications/pixelart/supplementary/v...

This method still wins out though.. but interesting never the less.

I think hq4x has a slight edge because it doesn't go all the way trying to make everything smooth, still preserving some pixelation. There's actually an analog to this in denoising: if you denoise too heavily you end up losing detail. Smart denoising manages to preserve edges, giving a better result. In this case, pixels are the same as noise, undesirable, but containing useful information.

xBRZ is pretty close: https://gfycat.com/FrequentWanCatbird

xBRZ can do wonders, especially for Link To The Past.
