Love these "tiny" 128x128 textures when meanwhile, anyone doing development for the contemporaneous Nintendo 64 gets something like 44x44@16bpp color, or 64x64@8bpp grayscale. The maximum texture size is 4 KB with some major caveats (e.g. it drops to 2 KB if you use indexed color).

The N64 is, in a lot of ways, on paper, a more powerful system than the PS1. Better CPU, depth buffer / Z test, perspective-correct texturing, antialiasing, subpixel precision, etc. And yet the PS1 completely dominated the N64 in the marketplace and in terms of longetivity--a big part of that how cheap it is to manufacture CDs. And so people lovingly remember PS1-style graphics, but there isn't as much of a resurgence of N64-style graphics.

Another cute thing to note about PS1 is how it renders dark clouds on-screen. You might be familiar with the "add" blend mode for things like lens flares. Well, the PS1 also had a subtract blend mode, which has some unusual effects... basically, anything partially obscured by a dark cloud gets darker but also more colorful.
