PAL vs NTSCWhat the difference actually meant for UK gamers

CH 01What PAL and NTSC actually are

Strip away the gaming baggage and PAL and NTSC are simply two ways of encoding a colour picture onto an analogue television signal. NTSC, named after America's National Television System Committee, was the older of the two, adopted in the United States back in 1941 and refreshing the screen sixty times a second. PAL, short for Phase Alternating Line, was designed later by Walter Bruch at Telefunken in West Germany, and it refreshed the screen fifty times a second. PAL's cleverness was in the name: by flipping the phase of the colour signal on alternate lines, it cancelled out the tint errors that plagued early NTSC sets, which is why NTSC picked up the unkind nickname "Never The Same Colour".

Those were television standards, not gaming ones. But a games console has to speak whatever language the telly in the corner understands, so machines and their games were built to match the local broadcast system. Over time the labels drifted from the signal to the whole region. PAL came to mean the UK, most of Western Europe and Australia; NTSC meant North America and Japan. When a collector today calls a SNES "a PAL machine", they mean a British or European one. The encoding gave its name to the entire ecosystem of consoles, cartridges and discs around it.

The two standards were never a straight swap, though, and the differences that seemed trivial on a broadcast of the news turned out to matter enormously once there was a game running on the screen.

CH 02The comparison, side by side

Two numbers do most of the work here, the refresh rate and the line count, and they pull in opposite directions. PAL redraws the picture less often but with more detail; NTSC redraws it more often with less.

On paper PAL looks like the winner. Nearly a hundred more visible lines is a genuinely sharper picture. The trouble is that almost every game of the era was written in the other country first, for that faster sixty-hertz screen. New to any of these terms? The retro glossary unpacks fields, refresh rates and interlacing in plain English.

CH 03Why PAL games ran slower, and had borders

This is the part that stings, and it comes down to one design habit. Classic game code doesn't keep its own clock; it advances the whole game by one step every time the screen refreshes. Move the hero, tick the timer, play the next note of music, once per frame. On an NTSC machine that happens sixty times a second, exactly as the developers intended.

Now feed that identical code a fifty-hertz PAL screen without changing anything, which is exactly what most publishers did. The game still advances one step per refresh, but there are now only fifty refreshes a second instead of sixty. Everything (movement, timers, music) happens at five-sixths of the intended pace, roughly 17% slower. A generation of British players grew up with sluggish jumps and heavy-footed characters and simply assumed that was how the games felt. The audio gave it away too: tied to the same slower clock, the music played back at a noticeably lower pitch.

Then there were the black bars. PAL's extra vertical lines meant a picture built for NTSC's 480 lines didn't fill the taller PAL frame, and rather than redraw everything to fit, developers usually just parked the smaller image in the middle. The gap showed up as thick black letterbox borders along the top and bottom of the screen, a permanent frame around a game that had never been resized for its new home.

It did get better. Later, more carefully made PAL-optimised releases were rebuilt to run at full speed and fill the screen, and toward the end of the analogue era hardware offered a proper escape hatch: a PAL-60 mode. The Dreamcast, for instance, would offer a sixty-hertz option at startup on games that supported it, giving PAL owners the correct speed at last. But for most of the 8- and 16-bit years, slower and letterboxed was simply the British default.

CH 04The upside PAL had

It would be easy to read all that as PAL being the poor relation, but the standard had two real advantages that collectors still enjoy today.

• A higher-resolution picture. That same extra vertical space that caused the borders also means PAL carries more detail when a game is drawn to use it. Around 576 visible lines against NTSC's 480 is a genuinely finer image (sharper text, cleaner edges) on hardware and software built to fill the frame.
• RGB on tap. Europe's televisions were built around the SCART socket, and SCART could carry a clean RGB signal directly. That made the sharpest possible analogue picture an inexpensive cable away for British players, while American collectors, whose sets never had SCART, spent years chasing converters to reach the same quality. If you want the full practical story, our RGB SCART guide is the companion to this page: it walks through exactly which of your consoles output RGB and which need a mod.

So the honest verdict is a trade, not a knockout. NTSC won on speed; PAL won on sharpness and on the connector that unlocked it. Now that you know why the picture looked the way it did, the next question is how to get the best out of it, which is what the guide to CRTs for retro gaming is for.

CH 05Region locking and the import scene

If NTSC games ran faster, the obvious question for any keen British player was: can I just buy the American or Japanese version? Sometimes, but the console makers went out of their way to stop you.

Nintendo were the strictest. Their cartridge consoles carried a lockout chip (the 10NES / CIC system, introduced in 1985) that performed a handshake with a matching chip inside every genuine cartridge and refused to boot a game from the wrong region. The SNES went further still, moulding two small tabs into its cartridge slot so a Japanese Super Famicom cart would not even fit a UK machine, a physical lock on top of the electronic one. Getting imports running meant a modification, an adapter, or a switch fitted inside the console.

Even once a game booted, the video standard could bite. An import running on a machine wired for the other region might come out in the wrong colour system or at the wrong speed, which is where 60Hz mods and, later, PAL-60 came in. It made the import scene a properly technical hobby, and it's the same tangle of cables, regions and sync signals that the Workshop below exists to help you unpick.

CH 06FAQ

What does PAL stand for?

PAL stands for Phase Alternating Line, a colour-encoding system for analogue television developed by Walter Bruch at Telefunken in West Germany. It became the broadcast standard across the UK, most of Western Europe and Australia, running at 625 lines and 50 fields per second. Because consoles and games were built to match the local television standard, "PAL" ended up as shorthand for the whole UK and European region: the machines, the cartridges and the discs, not just the colour signal it originally named.

Why are PAL games slower than NTSC games?

Because most were never adjusted for the slower refresh rate. Games written for NTSC advance their logic once per screen refresh, 60 times a second. Ported to PAL's 50Hz refresh without reprogramming, that same logic ticks only 50 times a second, so everything runs at roughly five-sixths speed: about 17% slower. Jumps feel heavier, the action is sluggish and the music plays at a lower pitch. Only later, better-optimised PAL releases were rebuilt to run at full speed.

Is NTSC better than PAL for gaming?

For speed, usually yes. NTSC's 60Hz refresh runs games at the pace their designers intended, with no slowdown and no black borders. PAL's advantage was a higher-resolution picture (about 576 visible lines against NTSC's 480) and, in Europe, SCART sockets that carried a clean RGB signal as standard. So NTSC won on motion, PAL won on sharpness. On original hardware neither is simply "better"; it depends on whether you value the correct speed or the higher line count.

What is PAL-60?

PAL-60 is a hybrid mode that outputs a 60Hz picture, running the game at its proper NTSC speed, while keeping PAL colour encoding so a European television can display it. It became common toward the end of the analogue era: the Dreamcast, for example, would offer a 60Hz option at boot on games that supported it, and later consoles moved the choice into a system menu. PAL-60 was the fix for the slowdown problem, giving PAL owners full-speed games at last.

Can I play NTSC games in the UK?

Often, but not always straight out of the box. Many consoles are region-locked (Nintendo's cartridge machines used a lockout chip, and the SNES even shaped its cartridge slot so Japanese carts would not physically fit), so an import game may refuse to boot without a modification or adapter. You also need a display that can handle a 60Hz signal; most televisions from the SCART era and every modern set via an upscaler can. Once those two hurdles are cleared, NTSC games run at their correct, faster speed.

What is the difference between 50Hz and 60Hz gaming?

The number is how many times a second the picture is redrawn. NTSC displays refresh 60 times a second; PAL displays refresh 50. Old game logic is tied to that refresh, so on a 50Hz signal an unoptimised game simply does everything a sixth less often. It runs slower and its audio drops in pitch. A 60Hz signal runs the same game at its intended speed. This is the root of the whole PAL-versus-NTSC speed story.
