Fortunately, the retro community has come together to research and create GameShark codes to disable software anti-aliasing. While you can mod a Nintendo 64 to output RGB video, taking care of the internal filter and anti-aliasing is a bit tougher. Additionally, almost every game featured some sort of anti-aliasing that further muddles the picture. This effect was arguably beneficial when playing on a CRT, but it’s terrible when you’re trying to upscale games on HDMI. There’s a blur filter applied to games that is intended to help soften the jagged edges of polygons.

In addition to lacking RGB, the Nintendo 64 has some wacky features built-in that degrade picture quality on HDTVs.

Unfortunately, the best you can get out of a stock N64 is S-Video, which, while better than composite, is still not ideal for upscaling and conversion to HDMI. Usually, all you need is the right cable and an OSSC or Framemeister, and you’re good to go. Most retro consoles from the fourth-generation on adapt pretty readily to modern TVs if you have the right equipment since they output RGB. Why does the Nintendo 64 look so bad on modern TVs?
