I bet that’s a slightly unfair representation of what it actually looked like. Graphics back then were purposely designed for how they would look on CRT tvs which add a lot of specific distortions to images. So taking a screenshot of a game running in an emulator without using a high quality crt filter added to the image will be a very untrue representation of what the game actually looked like.

(Don’t get me wrong, I’m not saying it actually looked great when displayed correctly, but i am saying it would’ve looked considerably better than this emulator screenshot)
