Old Nintendo games look very different from what people remembered them as. They’re not crazy, or blinded by nostalgia – the games really did look a lot better.
The secret is the CRT monitor.
The CRT – and Pixels
A pixel is defined as the smallest controllable unit of an image on-screen. This has changed some over time! In old digital clocks, the bars making up the numbers would act as its pixels. In CRTs, it was little cubes where the red, green, blue, and white projection lights lined up to give that cube the right color.
Old-style living-room CRTs usually had a resolution of 480p. When you see a number followed by ‘p’, like 480p, it’s referring to the number of rows of pixels lined up top-to-bottom, so any screen could theoretically be 480p – it’s just more impressive the smaller the screen is. 480p was the standard for many late 90’s/early 2000’s games, because CRTs were widely available. CRTs weren’t bad, for the time! Rear-projection models could get huge, but the kind that blasted the image directly onto the screen was limited to a size of about 30”.
CRTs also had the unique ‘CRT grid’. Because of how CRTs work, the individual pixels didn’t connect to each other neatly like they do on modern screens – a small outline of darkness surrounds each pixel. The pixel inside said outline isn’t perfectly ‘square’, either, like they are on modern displays. If you get up close to a CRT screen (don’t, it’s bad for your eyes) you’d be able to see the three colors being projected onto the glass of said screen, and they form a squarish blob or a series of colored lines, depending on brand. When you back up, it looks like a picture, and your brain automatically fills in the gaps left by the un-connected parts. This is a huge part of why these games don’t look as good as they used to! Current monitors don’t have gaps visible to the naked eye between pixels.
Old Games
Game designers were able to factor this in to give the illusion that the image was much clearer than it was – Pikachu in 480P looked incredible back then, but terrible today in that same 480p. Nostalgia hasn’t clouded vision, Pikachu really did look a lot less blocky. The CRT’s rounded off pixel-corners meant that developers could fill those pixels in right to the edge and still get a polished, rounded appearance – your brain, as mentioned previously, is also filling in gaps for you, as a sort of optical illusion. They couldn’t make a perfectly smooth curve, so they let you do it.
In absolute terms, games looked slightly worse before they got much better. 3-D games especially. Two-dimensional sprites could be fudged – there’s only so many positions for the characters to be in, so animate a jumping sequence, an attacking sequence, etc. and you’re good to go. Those games often still look great on modern monitors. 3-Dimensional games had to build a doll that the player could control and view from every angle, which was a lot for early computers. Their saving grace was that CRT – characters could be flawed and un-specific without being unreadable. With CRTs in the mix, many people didn’t notice that the PS1 games looked very different from PS2 games at the time, unless they were fancy and upgraded their screen without also upgrading to the next console. With the benefit of hindsight, games that were only a few years apart do look really different: Resident Evil 4 doesn’t look too bad on a modern screen, while Resident Evil 2 looks noticeably dated in comparison! But at the time, Resident Evil 3 looked marginally better than 2, and 4 only looked a little better than 3.
Most gamers never noticed that their old games were secretly ugly until many years down the line, in the modern era. Even that’s not a really fair statement – they weren’t ugly when they went in. It’s like trying to watch one of the old-style 3-D movies without the glasses, they were designed to be played on CRTs. We’re just noticing this now because emulators and ROMs for dead or missing games are more available than ever!
Emulators
Nowadays, with our perfectly square pixels, Pikachu looks much more… square. In fact, everything from old games does. Old games had very limited computer power to work with, so little hacks and tricks like this kept the games running smoothly. Blocky Pikachu is barely noticeable, but leaving him without fine detail frees up enough space to add extra plant textures to the island. Unfortunately, ROMs bring the old game to life without its limitations – the CRT monitor’s grid isn’t easy to recreate in a visually appealing way.
The original games with this art style weren’t meant for modern screens. The consoles are producing the same images now as they did back then, it’s just much clearer. I’m sure when we get to a point where projection or VR games are common, these old “3-D” games will look like trash compared to real 3-D, and it won’t be an accurate representation of the way we played those games.
Right now, the best option to get those nice-looking characters back is to recreate the CRT’s grid over top of the image, which many ROM creators are reluctant to do – many players would rather have a slightly uglier game in high-res than a more attractive game in low-res.
As a result, players are unintentionally led to believe the game really was that ugly. It just wasn’t.
At least the audio still sounds the same!
