TIPS / TRICKS

VIDEO & AUDIO

RGB, SCART eller HDMI?

RGB, SCART and HDMI are three different things. RGB describes a video signal, SCART is a connector/cable system, and HDMI is a digital connection. So it is not quite correct to ask whether “SCART is better than RGB” – a SCART cable can carry either composite video or RGB, and image quality depends on the signal the console and cable actually use.

From RF to RGB

The oldest consoles were often connected via RF, where picture and sound are combined into a TV signal. Composite is a step up and normally uses the yellow RCA plug for video. S-Video separates luminance and colour and typically gives a cleaner picture. RGB keeps the red, green and blue picture components separate and can provide a significantly sharper and more stable analogue image on compatible consoles.

In Europe, RGB is especially relevant because many CRT TVs have a SCART input. But a connector that looks like SCART is no guarantee of RGB: cheap cables and small RCA-to-SCART adapters often carry only composite video.

What about Component?

Component/YPbPr typically uses three video plugs and is not the same as RGB, even though the cables are often red, green and blue. On systems such as PlayStation 2, Wii and original Xbox, Component is often an excellent option and can also support progressive resolutions where the console and game allow it.

HDMI and modern TVs

Most classic consoles do not output HDMI directly. On a modern TV, the analogue signal therefore has to be converted. A cheap “AV2HDMI” box may produce a picture, but it can add lag, incorrect aspect ratios and poor scaling. A retro-orienteret scaler is designed for low resolutions such as 240p/288p and can convert RGB, Component or other signals to HDMI in a more controlled way.

REGION & HASTIGHED

PAL vs. NTSC – which is best?

PAL is mainly associated with Europe and Australia, while NTSC is associated with North America and Japan. In retro gaming, the terms are often used as practical shorthand for TV standard, refresh rate and game region, even though technically they are not exactly the same thing.

50 Hz mod 60 Hz

On many older European consoles, PAL games run at 50 Hz, while NTSC versions typically run at around 60 Hz. If a game was originally developed for 60 Hz and then converted to PAL without proper optimisation, the PAL version can feel slower and may have black borders at the top and bottom.

This is far from true for every PAL game. Developers learned to optimise better over time, and many later consoles and games offer a 60 Hz mode. Each title should therefore be judged individually rather than assuming every PAL version is worse.

Resolution and PAL60

Classic PAL television has more active lines than NTSC, but that does not automatically mean a “better” game image. The game’s graphics, port and selected video mode are what matter. PAL60 later became a practical middle ground on compatible equipment: 60 Hz timing combined with PAL-compatible colour encoding over composite/S-Video.

What should a European collector choose?

If you want to collect the versions originally sold in Denmark and the rest of Europe, PAL is the natural choice. Import versions can be interesting because of 60 Hz, different cover art, censorship differences or games that never came out in Europe, but they may require a different console, modification or region-free solution.

HARDWARE

Console maintenance

Retro hardware is often 20, 30 or 40 years old. That does not mean everything must be taken apart and refurbished immediately. The best maintenance starts with clean storage, correct power and good ventilation.

Day to day

Keep ventilation openings free from dust and give the console room to dissipate heat. Avoid direct sunlight, damp basements and places with large temperature swings. Do not place heavy objects on top of the machine, and do not coil cables so tightly that they develop permanent kinks.

Power supply

Use the correct original power supply or a well-documented replacement with the correct voltage, polarity and sufficient current capacity. A plug fitting physically does not mean the power supply is compatible.

Cartridge and controller ports

If games or controllers lose connection, start by cleaning the game or connector rather than immediately bending contacts inside the console. Repeated mechanical “adjustment” can make connectors worse. High-purity isopropyl alcohol can be used sparingly on accessible electrical contacts while the machine is fully powered off and unplugged, and everything must be completely dry before power is restored.

Optical drives

CD/DVD drives have mechanical parts that wear out. If a console struggles to read discs, first check the condition of the disc and clean it. Avoid randomly adjusting the laser potentiometer: excessive power can shorten the laser’s life and mask the real fault.

Batteries and capacitors

Some cartridges and consoles contain batteries for clocks or saved data. Old batteries can run flat and should be replaced correctly. Capacitors can also age, but “recapping” should be based on the machine’s condition and known failure patterns – not simply because the console is old. Leakage, corrosion, unstable video/audio or power problems should be investigated by someone with experience.

GAMES & MEDIA

How to clean games

Different media should be treated differently. The goal is always to use the least aggressive method first.

Cartridges

First wipe the plastic shell with a soft, slightly damp cloth without allowing liquid into the game. If the contacts are dirty, they can be cleaned carefully with a lint-free swab or foam swab using a small amount of 90%+ isopropylalkohol. Clean in the direction of the contact and let the game dry completely before use.

If dirt is stubborn, it is better to open the cartridge shell with the correct security bit and clean the board in a controlled way than to pour liquid through the opening. Be careful around labels: alcohol and water can damage printing, adhesive and surfaces.

CD, DVD and Blu-ray

Hold the disc by the edge and avoid touching the data side. Remove loose dust first. Then use a clean microfibre cloth and wipe straight from the centre toward the edge. Avoid circular motions. For greasy fingerprints, a small amount of suitable mild cleaning fluid can be applied to the cloth – do not pour it directly onto the disc.

Scratches

A dirty disc can often be saved by cleaning, but deep scratches may require professional resurfacing on CD/DVD-based media. Blu-ray has a different protective structure and should not automatically be treated with the same abrasive methods. Home remedies involving toothpaste, abrasives or polishing machines can make the damage worse.

COMPATIBILITY

Region locking explained

Region-lock is a restriction intended to prevent software from one sales region from running on hardware from another. In the retro world you will typically encounter the terms PAL (Europe/Australia), NTSC-U/C (North America) and NTSC-J (Japan).

Physical region locking

Some cartridge systems use different cartridge or slot shapes. An imported game can therefore be electrically close to compatible but simply not fit physically. Other machines use additional lockout mechanisms or chips that check the region.

Software-based region locking

On disc-based systems, region checking is often part of the console firmware or boot process. PlayStation and Sega systems from the period can, for example, reject an original disc from another region even though the physical disc format is the same.

Region-free does not mean problem-free

Even when a console or game is not locked, there can still be issues with 50/60 Hz, video standards, language, online features, DLC or accessories. On older TVs, an imported game may display in black and white or not at all if the display does not accept the signal.

Modchips, adapters and mods

Region adapters, boot discs, switches and modchips exist for many systems. Some solutions only change region checking, while others can also switch 50/60 Hz. It is important to research the specific console revision because one method does not necessarily work for every model.
