RGB SCART for Retro ConsolesThe RGB guide to the best picture in the UK

CH 01Why RGB, and why Britain had it easy

Every classic console has to squeeze a colour picture down a cable, and the quality of that picture is decided almost entirely by how the cable carries it. The worst option mashes brightness, colour and sync into a single wire. That is the RF aerial lead and the yellow composite plug, and it is why so many people remember these games as a soft, smeary blur. RGB keeps the three colour channels (red, green and blue) on their own separate wires, delivered to the screen exactly as the console generated them. Nothing is mixed, nothing has to be untangled at the other end, and the result is the crisp, saturated image the games were designed to show.

Here is the quiet advantage of being a British collector. RGB was carried across Europe by the SCART socket, the big 21-pin plug on the back of almost every telly sold here from the late 1980s onward. SCART was a European standard, made compulsory on new sets in France from 1980 and common across the UK through the whole console era, and it was wired to accept RGB directly. Our PAL consoles were built to send RGB down it. America never adopted SCART at all, so US collectors spent years chasing component video and expensive converters to reach a picture that, over here, an inexpensive cable into a car-boot telly simply hands you.

The catch is that not every console cooperates equally. Some send RGB out of the box; some hide it inside and need surgery to release it. The table below is the whole map: which of your machines gives you RGB for the price of a cable, and which asks for more.

CH 02The RGB capability matrix

Read it as a shopping list. Yes means a native output. Buy the right RGB SCART cable and you are done. Mod means the console cannot do RGB from a cable alone and needs an internal modification first. Region matters: PAL and NTSC machines are wired differently, and a cable made for the wrong one can damage your gear.

The headline is a happy one. Four of the five best-loved consoles of the 16- and 32-bit eras (SNES, Mega Drive, PlayStation and Saturn) hand you RGB for the cost of one good cable. It is Nintendo's two machines, the NES and the N64, that make you open the case. New to any of the terms above? The glossary unpacks csync, composite, VDP and the rest.

CH 03Which RGB SCART cable do I need

Once you know a console outputs RGB, the only job left is buying a cable that actually carries it, and this is where most people quietly get robbed of the picture they came for.

• The £3 "SCART cable" is the classic trap. A SCART plug can carry RGB, but it does not have to. Generic marketplace leads are wired for composite only: a single mixed signal runs through the connector and the red, green and blue pins sit unconnected. It fits your console, it shows a picture, and it is not RGB. If a listing does not say "RGB" in as many words, assume it is composite.
• Buy a cable made for your exact console. The pinouts differ machine to machine, and region matters: a PAL SNES and an NTSC SNES need different wiring, and using the wrong one can genuinely damage hardware. UK specialists like RetroGamingCables and Retro Access build console-specific leads with the correct pinout and the small components (resistors and capacitors) each system needs.
• Understand the sync question in plain English. RGB carries colour but not timing, so the display needs a sync signal alongside it. The cleanest is a dedicated csync line; cheaper cables borrow sync from the composite or luma signal, which can add faint interference. Where a console (like the PlayStation) cannot produce csync itself, a good cable does it with a tiny separator circuit built into the plug.
• Official beats generic, but well-made third-party beats official. Sega and Sony's own RGB leads were fine in their day; today the best picture comes from enthusiast-built cables using proper shielding and csync. It is a small premium for a visible difference, and a one-time purchase.

If you have the console sorted and the right RGB cable in hand and are still staring at a blank or wrong-looking screen, that is exactly the kind of puzzle the Workshop below is built to untangle.

CH 04FAQ

Does the SNES output RGB?

Yes. Every original full-size Super Nintendo and Super Famicom outputs RGB straight from its Multi AV Out port with no modification. You just need the correct RGB SCART cable for your console's region. PAL and NTSC machines are wired differently, so a cable made for the wrong region can damage your equipment; buy a cable that matches, or a properly-built universal one. The only quirk is the rare 1CHIP-03 revision, which needs a small internal sync modification.

Does the Nintendo 64 output RGB?

Not on a standard console. The N64 generates RGB internally but Nintendo never wired it out to the AV port, so a stock machine cannot give you RGB from a cable alone. Early NTSC units carry a video DAC that a soldered RGB mod board (such as the popular N64RGB or Tim Worthington boards) can tap; later revisions and every PAL N64 lack that chip entirely and need a mod that regenerates the signal. In short: N64 RGB always means an internal modification.

Is RGB SCART better than HDMI for retro consoles?

On a CRT, yes. RGB SCART is the source-quality analogue connection, carrying the three colour channels separately with no scaling or lag. HDMI does not exist on these consoles natively; you only get it by adding an internal digital mod or by feeding the console's RGB into an external upscaler such as an OSSC or RetroTINK. So even the HDMI route usually starts with a clean RGB signal. For a CRT, RGB SCART is the destination; for a modern TV, it is the first step.

Why is my SCART cable not giving me RGB?

Because most cheap SCART leads are wired for composite video only. SCART can carry RGB, but the connector does not have to. A generic lead from a marketplace almost always routes a single composite signal through the yellow-equivalent pins and leaves the red, green and blue pins unconnected. It fits, it shows a picture, and it is not RGB. You need a cable built specifically for your console and explicitly described as an RGB SCART cable.

What is csync?

Csync, or composite sync, is a clean timing signal that tells the display when each line and frame begins. RGB carries only colour, so it needs a separate sync signal alongside it. Better cables deliver a dedicated csync line, which gives the most stable picture; cheaper ones borrow sync from the composite video or the luma signal instead. Some consoles output csync directly, while others (like the PlayStation) need a small sync-separator circuit built into the cable to produce it.

Can I use an RGB SCART cable in the US?

Not directly. American televisions never had SCART sockets. SCART was a European standard, so US sets topped out at composite or, later, component video. To use RGB SCART kit on an NTSC display you feed the SCART signal into an upscaler such as an OSSC or RetroTINK, which converts it to HDMI. The cables and consoles still output perfect RGB; it is only the television socket that Americans were never given.
