Honestly, I hate the CRT aesthetic. I grew up with CRTs. Leaving them behind for LCDs was one of the greatest transitions of growing up. By all means, enjoy them if you do, but I don’t.
It’s not just the look of it, but the art and games were designed with the limitations of CRT in mind. Not all games off course. An example is the transparency effect on Genesis / Mega Drive:
Shaders are not only useful for CRT emulation, but also to get the look of handhelds:
Ah jeez, this picture triggered the earworm! Now that song is in my head!
Does this shader also replicate the horrific motion blur that the display of the original GameBoy suffered from?
You’ll never catch me using filters like these voluntarily. Inject those crisp pixels straight into my vein.
My aim was never to emulate but to play. Blur filters are something that I won’t be using.
I strongly disagree with the premise that there’s a “wrong” way to play retro games. Don’t gatekeep. Imagine if people told you not to listen to Pink Floyd unless it’s on vinyl. It would be lost media.
That said, CRTs present images fundamentally differently than LCD displays, and a lot of developers took advantage of those idiosyncrasies. There are scanlines everywhere. CRT phosphors aren’t square, and appear smaller when darker. Bright pixels can “bleed” into nearby pixels, particularly when using composite signals.
Before LCDs, many (not all) pixel artists used this to their advantage, basically harnessing the imperfections of analog TV to provide equivalents to anti-aliasing, bloom, extra color depth, and even transparency. Some particularly famous examples came from Sega Genesis games. This video goes into good depth on the whys and hows, and there are some solid examples of the outcomes here.
I’ve attached examples below (hopefully they upload). If you like the raw pixel art, then no harm done. Enjoy! But if you like the way CRTs interpreted and filtered those signals, you owe it to yourself to look up some shaders for your favorite emulator.

I understand your sentiment here and you are right too. What I think is, that the wording on this title here is misunderstood. Emulating (old) games without Shaders is not faithful or accurate in the looks. It looks “vastly” different and thus means it looks “wrong”. I interpret the “wrong” in the title as “not faithful”, instead as “bad”, like this: You’re Probably Emulating Retro Games Not Faithful (you need CRT Shaders for the oldschool look)
The benefit of CRTs is most apparent in pre-rendered backgrounds (See Final Fantasy, Resident Evil). These backgrounds look incredible with shaders, and, indeed, on real displays.
Good looks stay good.
