The raw pallette Nintendo video with NTSC filters looks amazing in RetroArch on a modern screen. It looks like how I remember. I’ll see if I can find a screenshot of mine later.

Eh, I’ll just show some from search results. Notice how the color bleeds between pixels, and edges have color artifacts.

Also, check out this amazing Game Boy filter!

I disagree completely. The pixel art Castlevania games on Nintendo DS look amazing! So many little details. It’s fantastic.
