Having some options for integer scaling/nearest neighbour/pixel doubling or whatever other name exists for that would be great. Sure the pictures are gonna be "blocky", but that just means they'll look like the original looked on a screen at the time, minus CRT screen blurriness. I find this better than straining my eyes on a tiny image or dealing with atrocious upscaling algorithms that change an image from "imagine the details" to "look at these ugly distorted details".
