The SNES: The Perfect 16-Bit Machine

How the Super Nintendo Proved Specs Aren’t Everything

I’ve been playing video games since the Atari 2600. I keep stacks of CRTs running on dusty shelves in my basement in Minneapolis. I have an accounting degree, so I think in systems. If someone tries to sell me on some wide sweeping philosophy without understanding the technical mechanics behind it, I get very irritated. That’s why when people try to tell me that the Genesis was better than the SNES I don’t get angry. I pull up specs.

Because looking at raw technical specs you’ll likely land on the Genesis. The SNES wouldn’t win on processing power. But console design isn’t about raw processing power.

The Super Nintendo Entertainment System launched November 21st, 1990 in Japan as the Super Famicom and August 13th, 1991 in North America. Nintendo sold 49.10 million units worldwide. No console wars are won on business strategies and licensing deals. Console wars are won by having a better console. The SNES was better because Nintendo understood what 16-bit gaming needed to be.

The Architecture of Innovation

Nintendo chose to power the SNES with the Ricoh 5A22 CPU with a 65c816 core clocked at a variable frequency of 3.58 MHz. That’s already twice as fast as the NES CPU, which operated at 1.79 MHz, but it wasn’t far enough ahead of its greatest competition.

The Sega Genesis was powered by a Motorola 68000 CPU clocked at 7.67 MHz. If you go by raw processing power, the Sega Genesis was more than twice as fast as the SNES. So why did the SNES come out on top?

The SNES simply had better architecture. Programming for the SNES was more efficient because Nintendo designed a console that was better able to handle what 16-bit games should be doing. First let’s look at memory. The SNES had 128 KB of main RAM. The Genesis had half as much at 64 KB.

That extra memory made a difference. Memory wasn’t a bottleneck for game logic on the Genesis, but it was better on the SNES. Game developers could store more variables, they could create larger overall game states, they could account for more moving parts. Developers were frequently pushing what the SNES could do, and they had more RAM to work with when they did it.

Having 64 KB of video RAM was better than the 32 KB of video RAM on the Genesis. The SNES even had 64 KB of RAM dedicated to audio output. By comparison, the Genesis combined game logic and audio playback duties, having to use RAM for both functions.

128 KB of RAM allowed SNES games to include more sprites on screen without slowdown. Each sprite could also be larger without taxing the SNES hardware. Audio channels could play more sophisticated sounds because the SNES had hardware dedicated to sound effects and music playback. Every channel could play audio simultaneously without dropping game logic because there was RAM to store what each channel was playing.

Gamers praised SNES games for having better audio than Genesis games, and that wasn’t because composers had suddenly gotten better. It’s because Nintendo gave developers better tools to work with. Better audio architecture meant SNES games sounded better.

Let’s talk about why SNES games looked better. Visual output starts with memory. Then you have to consider how graphics were rendered onscreen. The SNES could display between 256×224 pixels and 512×448 pixels. Colour-wise, the SNES could display 32,768 colours at one time. The Genesis could only display 512 colours at once.

Genesis colours aren’t worse, they just worked differently. The SNES used a palette system that allowed gamers to see more varied colours onscreen at once. But when it came time to render sprites and background tiles those tiles could be larger and more complex on the SNES.

It wasn’t just sprite sizes. The SNES could display four layers of scrolling backgrounds. You could have multiple layers moving at independent speeds simultaneously. Games like Super Mario World could create depths of field and movements onscreen you simply didn’t see on the Genesis.

Mode 7 effects would be the real killer app. Mode 7 allowed the SNES to rotate and scale backgrounds. Games like F-Zero used Mode 7 effects to make the SNES look like it was outputting 3D graphics that it wasn’t capable of producing. Raw processing power doesn’t do that. Innovation does.

The Secret Weapon Nobody Talks About: Audio

People forget how bad Sega’s audio was compared to the SNES. The SNES had an 8 channel ADPCM system sourced through a Sony SPC700/DSP clocked at 32 kHz that allowed for stereo sound playback. Each channel could play back high-quality audio samples that were stored on the game cartridge itself.

The SNES didn’t just have more audio channels. It had a better audio architecture than the Genesis. Developers were able to create better soundtracks for SNES games because Nintendo offered tools that were simply better than what Sega was offering.

Listen to the soundtrack of Chrono Trigger. Listen to Final Fantasy VI. Listen to Super Metroid. Sega had talented composers too. But Nintendo had created an audio environment that allowed composers to create audio that sounded fuller and more lifelike.

The Games: Titles That Required Incredible Hardware

The SNES simply had better games. Not just more games than the Genesis. Better games that knew how to push the hardware and do things that Genesis games simply couldn’t match.

Super Mario World isn’t just one of the best platformers ever released. Mario World knew how to use all the bells and whistles the SNES had to offer. It knew how to use layered scrolling backgrounds and Mode 7 effects to make the game look better than any Genesis game could hope to.

It wasn’t just technical specs that made The Legend of Zelda: A Link to the Past what it was. More RAM meant Link’s darker world actually had to track the state of every screen whether it was lit or not. Everything you burned had to be burned a second time.

Final Fantasy VI was a game of such unprecedented scope that it demanded every advantage the SNES had to offer. Between characters, towns, overworld, dungeon interiors, FFVI had it all. And after that game’s midpoint where literally the world ends, you spend the rest of the game exploring a world that reacted to your actions.

Chrono Trigger showed the world how JRPGs were meant to be played. Multiple endings based on defeating the final boss at certain intervals. New Game+ that allowed you to keep your progress past the credits. FFVI had gameplay and scope you didn’t expect a SNES game to handle.

Super Metroid created a legacy of game design expectations that modern games still struggle to live up to. Exploration felt smooth. Controls were tight. The map actually encouraged you to explore without handholding you throughout the process.

Yes the Genesis had great games. But Nintendo built a better system that allowed their developers to achieve greatness.

The Controller Everyone Forgot About

The SNES had the best controller of any console during this era. It improved on one of the best designs in gaming history. It basically took the NES controller and upgraded it across the board.

Four face buttons instead of two. Arranged in a diamond instead of a straight line. Shoulder buttons were better than what the Mega Drive offered. It was more ergonomic. It fit your hands better. The D-pad might have been even better than the NES controller because Nintendo maintained the level of precision that made the original Nintendo legend.

Every modern controller borrows from the SNES layout. Xbox controllers, PlayStation controllers, all of it traces its design theory back to the SNES. Games were built to accommodate this controller. Developers knew the limits of what players could do. It didn’t take long to learn how to use the SNES controller because it was intuitive.

Cartridge Factories: Building Something That Would Last

SNES cartridges were better built than Genesis cartridges. They simply were. The contact pins were better resistant to corrosion. The cartridges themselves felt more durable. Thirty years later Genesis cartridges are far more likely to have issues than SNES cartridges.

SNES cartridges fit better in the console. The slot on the SNES was stronger. The connection was more reliable. You didn’t have to worry about your cartridge properly connecting to the console. With Genesis consoles you often had to wiggle the cartridge to connect. You had to blow into cartridge ports to get them to work.

With SNES consoles you simply inserted the cartridge and it worked.

The Bottom Line: Sales

The SNES sold 49.10 million consoles worldwide. Not as many as the NES which sold 61.91 million, but keep in mind that by the time the SNES was winding down the PlayStation was already hitting its stride. The SNES didn’t enjoy the NES’s longevity, but in terms of raw market dominance in the 16-bit era, Nintendo dominated.

Genesis had a lot of excellent games as well and competed fiercely with Nintendo. But Nintendo executed better and that’s why they won.

Why Specs Matter…And Why They Don’t

The reason the SNES outsold the Genesis doesn’t just have to do with better game design. When you’re talking about console hardware you have to factor in how well the system was built.

Better RAM, better audio output, more responsive controls, higher repairability, it all added up to Nintendo having a better console. And when gamers had to choose which console to buy they chose Nintendo.

Still Got it?

I’ll be the first to admit I spent a chunk of quarantine playing SNES games. But I didn’t do it out of some misplaced nostalgia. I did it because I wanted to see if Nintendo’s engine still held up. Let’s go down the list.

Controls still feel tight. Graphics still look crisp and easy to read. Colour palettes are well chosen. Music is wonderful. Every game I threw at it reacted how I wanted it to. Super Mario World is as close to a flawless platformer as you’re going to find. The controls on A Link to the Past are as responsive as ever.

FFVI was every bit as emotionally powerful as I remembered. Samus Aran is still goddamned awesome. Even Castlevania: Aria of Sorrow felt fantastic to play.

The audio still holds up because Nintendo created an audio architecture that allowed composers to make darn near orchestral quality music right on your TV.

Granted I’m picking games with built legacies here. But Nintendo has a catalogue full of games that are just as good as these. Every major SNES game I put into that console was everything I remembered and then some.

Console itself still feels great. Cartridges still work. Controllers still feel amazing in your hands. Power supply still works. You can go buy a SNES today and it will turn on and work. That’s because it was built to.

The Bigger Lesson

The SNES is able to do more with less. Sure it didn’t have the best CPU on paper, but Nintendo’s engineers realised that and focused their efforts in other areas. Better graphics handling. Better audio. More RAM. Tricks like Mode 7 effects that no other console could reproduce.

That’s the beauty of the SNES. Raw processing power doesn’t win you friends. Innovation does. Better architecture does. Knowing what your hardware needs to accomplish and building your console around those goals.

Mode 7 effects is a prime example of this philosophy at work. Mode 7 was fundamentally just a graphics transformation technique that could rotate and scale backgrounds on the SNES. Want to know why you never saw that on the Genesis? It wasn’t because their processor couldn’t handle it.

It’s because Sega never focused on that aspect of game design. Nintendo did because the SNES could handle it. More than that, it could handle it well.

The Japanese Engineering Advantage

One of the biggest reasons Nintendo came out on top was because they knew how to build hardware better than anyone else. Little things added up over time. The attention to build quality. The extra latch on the cartridge port.

Japanese game design philosophies really came into focus with the SNES. The level of care and detail you see in Mode 7 effects. Japanese developers knew how to push the limits of what games could do. Japanese consoles were designed to match that ingenuity.

Outro

Perfect is a strong word. But when you talk hardware and practicality the Super Nintendo Entertainment System is as close to perfect as you’re going to find from the 16-bit era.

Everything about the SNES from a hardware perspective was designed to offer gamers something better than what Sega was providing. They had a better library because their hardware allowed for it. Japanese developers understood the system better and were able to push the limits of gaming in ways US developers didn’t comprehend.

Not one part of the SNES was flawed in terms of design. Nothing was overlooked. Everything was better than what Sega offered. Sales proved it. Hardware lasting decades proves it. Even the games still hold up against modern standards because Nintendo designed a system that allowed developers to create timeless games.

Now go blow into a Genesis cartridge.
