Quick Answer
Every retro console needs specific cables: NES/SNES use composite RCA (£8-15) or RGB SCART (£20-40), Genesis uses same RCA, N64 uses S-Video (£10-20), PlayStation uses composite RCA or component (£15-25), Dreamcast uses VGA (£15-25). Best option: buy SCART RGB cables (£25-40) if your TV/monitor supports it – they’re sharper than composite. If using modern TV without SCART, buy HDMI converter (£50-150). Total for full setup: £60-200. Don’t use RF cables (too blurry) – use at least composite RCA, ideally SCART RGB or S-Video.
Introduction: Why Cable Quality Matters for Retro Gaming
Before diving into specific products and comparisons, it’s essential to understand why choosing the right cable makes such a dramatic difference to your retro gaming experience. This isn’t marketing hype – it’s physics and electronics.
Retro consoles output analog video signals that are fundamentally different from modern digital signals. These analog signals are vulnerable to interference, degradation, and signal loss. The quality of your cable and connector determines whether the signal reaches your TV crisp and clean, or degraded and blurry.
The Signal Path Explained:
When you play Super Mario Bros on an NES, here’s what happens:
- NES motherboard generates a video signal (tiny electrical pulses)
- Signal travels down the cable to your TV
- Cable’s shielding protects signal from interference
- Connector transfers signal with minimal loss
- TV receives signal and displays it
Each step introduces potential quality loss. Poor cables allow interference. Bad connectors create resistance. The cumulative effect is visible: blurry picture, ghosting, color bleeding.
Real-World Example:
Imagine you’re playing The Legend of Zelda on NES:
- With RF cable (original): Text in menus is unreadable blurry blur. Link’s sprite looks fuzzy. Colors look muddy. Difficulty reading health counter at top. Game looks “old and broken.”
- With composite RCA cable (£10 upgrade): Text becomes readable. Link’s sprite is clear. Colors are vibrant. Health counter visible. Game looks significantly better.
- With S-Video cable (£20 upgrade): Even sharper than composite. Sprite edges crisp. No color bleeding. Text crystal clear.
- With RGB SCART cable (£30-40 upgrade): Arcade-quality image. Looks like playing original arcade cabinet. Perfect clarity and color accuracy.
This isn’t subjective opinion – it’s measurable signal quality. The difference between RF and composite is so dramatic that people often say “I never realized NES was capable of this quality!”
Why This Matters:
Original cables often came with consoles in 1985-2005 when CRT TVs were standard and RF was acceptable. Modern flat-screen TVs don’t handle RF signals well. Even composite, while better than RF, isn’t optimal for many consoles.
Upgrading cables costs £10-40 but improves your experience by 50-200% depending on starting point. This is one of the single best investments you can make in retro gaming setup.
Understanding Different Cable Types: A Technical Deep Dive
1. SCART RGB – The Gold Standard (£20-40)
What it is: SCART (Syndicat de Couleur Audiovisuel Radio Television) is a European standard connector that carries separate RGB signals. This means red, green, and blue video information travels down three separate, shielded channels instead of being combined into one signal.
Why this matters: This is the fundamental difference. Composite video takes three pieces of color information and combines them into one signal. Your TV then has to decode them back out – a process that inevitably loses information and introduces errors. It’s like sending three different radio stations over one frequency.
RGB sends each color separately. No decoding needed. No information loss. What you see is exactly what the console outputted.
Specifications:
- 21-pin SCART connector (European standard)
- Separate channels: Red, Green, Blue, sync signal
- Audio: Usually separate RCA cables
- Resolution: Up to 720p (though retro consoles output 240-480p)
- Buy SCART RGB cables (£20-40)
Quality ranking: Best possible analog video quality Best for: CRT monitors, enthusiasts with European equipment Compatibility: European TVs and monitors, many arcade cabinets
Visual Quality Example: Playing Super Metroid on SNES with RGB SCART to CRT monitor looks indistinguishable from arcade quality. Samus’s sprite edges are perfectly sharp. Background parallax scrolling is smooth. Explosion effects have perfect color accuracy.
Historical Context: SCART became the European standard in the 1980s-1990s. If you have a CRT monitor from Europe (which many enthusiasts prefer for retro gaming), SCART RGB is the native standard. Most European consoles have SCART connectors built-in.
Modern Challenge: Modern flat-screen TVs rarely have SCART inputs. If you want RGB quality on modern TV, you need a scaler/converter (£150-250) that converts RGB to HDMI. This is only for enthusiasts.
2. Component Video – The Practical Best Option (£15-30)
What it is: Component video is the closest consumer alternative to RGB. It separates video into three components: Y (luminance/brightness) and Pb/Pr (color information). This is still far better than composite but requires different connectors than RGB.
Why this matters: Component video is a middle ground – not as good as RGB’s separate color channels, but dramatically better than composite’s single-signal approach. Most modern TVs have component inputs, making this practical for real-world use.
Specifications:
- Three RCA connectors: Y (often green/yellow), Pb (blue), Pr (red)
- Audio: Separate RCA cables for audio
- Resolution: Full HD capable
- Compatibility: Most TVs manufactured 1995-2015 have component inputs
- Buy component cables (£15-30)
Quality ranking: Second best (90% of RGB quality) Best for: Modern TV setups, most people Compatibility: Highest compatibility with existing equipment
Visual Quality Example: PlayStation 2 with component cables looks noticeably sharper than composite. Text in Metal Gear Solid menus is crisp. Character models have defined edges. Textures are clear instead of mushy.
Installation Guide:
- Locate component inputs on TV (usually color-coded red/blue/green)
- Match colors: Y→green/yellow input, Pb→blue input, Pr→red input
- Separate red/white RCA cables for audio to audio inputs
- Power on console, switch TV to component input
- Immediate improvement in image quality
Why It’s Underrated: Many people don’t realize their TV has component inputs. Check your TV’s manual or look at the back – if you see three color-coded RCA jacks labeled Component, YPbPr, or Y/Pb/Pr, you can use component cables immediately.
3. S-Video – The Affordable Upgrade (£10-20)
What it is: S-Video (Separate Video) separates brightness (luminance) from color information (chrominance). It’s a middle ground between composite (everything mixed) and component (fully separated).
Why this matters: S-Video eliminates composite’s characteristic “rainbow effect” where colors bleed into adjacent areas. Text becomes more legible. Sprites appear cleaner. It’s like the difference between 480p blurry and 480p sharp – same resolution, much better clarity.
Specifications:
- Mini-DIN 4-pin connector
- Most retro consoles support natively
- Audio: Separate RCA cables required
- Quality: 3x better than composite, 70% as good as component
- Buy S-Video cables (£10-20)
Quality ranking: Good (70% as good as component) Best for: Budget-conscious buyers, N64 owners Compatibility: Most retro consoles and older TVs have S-Video
Visual Quality Example: Nintendo N64 with S-Video looks dramatically better than composite. GoldenEye’s textures are readable. Text in menus is clear. Ghosting effect from composite is completely gone.
Why N64 Owners Love S-Video: N64 is famous for producing blurry composite video. This isn’t a cable problem – it’s console architecture. But S-Video fixes it remarkably well. An N64 with S-Video cable is night-and-day difference from original composite. Many people say “I didn’t know N64 was capable of this!”
4. Composite RCA – The Budget Standard (£8-15)
What it is: Composite video combines all video information (brightness and color) into a single signal carried over yellow RCA connector, with separate red/white cables for audio.
Why this matters: Composite video is the baseline. Every CRT TV from 1960-2010 had composite inputs. It’s universal and cheap. But it’s the lowest quality analog video standard.
Specifications:
- Single yellow RCA connector for video
- Red/white RCA connectors for audio (stereo)
- Universal compatibility with old equipment
- Quality: Baseline (everything else is better)
- Buy composite cables (£8-15)
Quality ranking: Acceptable baseline Best for: Budget builders, testing equipment Compatibility: Highest universal compatibility
Visual Quality Example: NES with composite cable produces acceptable picture – readable text, clear sprites, decent colors. Not great compared to alternatives, but huge improvement over original RF cable.
When to Use Composite:
- First console in your collection (cheap upgrade from RF)
- Temporary testing setup
- As backup cable
- Budget-conscious gaming
- TV with only composite inputs (old equipment)
Upgrade Path: Many people start with composite (£10), then upgrade to S-Video (£15) or component (£20) later. The progression is: RF (terrible) → Composite (acceptable) → S-Video (good) → Component (very good) → RGB SCART (best).
5. RF Connector – Avoid This (£5-10)
What it is: RF (Radio Frequency) modulation was the cheapest way to connect gaming equipment to TVs in 1980s. The video signal is modulated onto a radio frequency carrier wave, sent through single coaxial cable to TV’s antenna input.
Why avoid it: RF cables produce the worst picture quality of any video connector. This is physics – RF requires demodulation in the TV, which degrades signal quality. For broadcast television it was acceptable. For gaming it’s terrible.
Specifications:
- Single coaxial connector (looks like cable TV connector)
- Signal quality: Worst possible
- Compatibility: Works with any TV with antenna input
- Cost: Cheapest option (£5-10)
- Don’t buy – upgrade instead
Quality ranking: Worst Best for: Nobody – this is what to replace Compatibility: Universal (too bad)
Visual Quality Example: NES with original RF cable: Menu text barely readable, sprites look fuzzy and ghosted, colors look muddy and washed out, overall appearance is “broken.”
Same NES with composite cable (£10 upgrade): Text perfectly readable, sprites sharp and clear, vibrant colors, looks professional.
Why Original Consoles Had RF: In 1985, RF was the only way to connect gaming equipment. CRT televisions had antenna inputs for broadcast signals. RF was cheap and worked with all TVs. But it was never good – it’s just what was available.
Immediate Action: If you have a retro console with RF cable, replace it immediately. Composite cable costs £8-15 and improves picture by 100-200%. This is the single best investment you can make in retro gaming.

Nintendo 64 – The Blurry Console
Important Context: N64 is famous in retro gaming for producing poor picture quality. This isn’t a cable problem exclusively – it’s console architecture. But the cable makes huge difference.
N64 outputs interlaced 240p signal. Composite video is terrible at handling interlaced signals. Result: ghosted, blurry image that looks “broken.”
S-Video fixes this dramatically.
Cable Options:
- Composite RCA (£10-20) – Notoriously blurry, famous complaint
- GoldenEye looks ghosted and unclear
- Text barely readable
- Not recommended
- S-Video Cable (£15-25) – HUGE improvement
- Buy N64 S-Video (£15-25)
- GoldenEye becomes playable and clear
- Text readable
- Dramatic improvement
- Highly recommended
- RGB Mod (£40-80) – Best quality
- Arcade-quality image
- Complex installation
- For enthusiasts only
Installation (S-Video):
- Buy N64 S-Video cable (£15-25)
- Disconnect original composite cable
- Plug S-Video cable into N64
- Connect S-Video to TV’s S-Video input
- Use separate RCA for audio
- Test – immediate massive improvement
Real-World Impact: This is one of the most dramatic upgrades you can make. People who think N64 looks bad often haven’t tried S-Video. The improvement is night-and-day.
PlayStation 1 & 2
