Related: is there any "high resolution" version of setup.bmp (https://raw.githubusercontent.com/grassmunk/Chicago95/5670fd...) that does not kill the spirit of it? I tried upscaling it, but it's like upscaling pixel art...

I guess my best bet would be retaking the original pictures (the OG MS Natural Keyboard, CDs, etc.) and recreating it, but it sounds like plenty of work

For dithered images I find waifu2x with the noise removal at 'None' to be pretty good at scaling these things up without destroying the dithered shapes.

Unrelated (Maybe related actually) this tool for applying old-school style dithering to an image with a bunch of settings and dithering algos: https://doodad.dev/dither-me-this/

I actually tried waifu2x from mobile, and it looks good! Not sure if it will work as a desktop background, but thanks for the tip!

You probably already thought of this, but this looks like a 1-bit dithered image (maybe Floyd-Steinberg?) so maybe you can blur it to get something like the original image, then scale it up, and apply the dither again.

You could scale it without interpolation, giving you a crisper image at larger resolutions without blurring or smoothing.

yes, technically that is possible, but it would give you an image with... big square blocks instead of tiny pixels.

I'm thinking of achieving something like https://github.com/nestoris/win98wallpapers, and maybe Midjourney's img2img (as the other commenter suggested) might be able to do something like that, I don't know.

How about scaling with Midjourney's img2img (if it will do a wallpaper size image?).
