Retro video cables (SCART, composite, S-Video)

Retro video cables carry the original analogue signals: RGBS over SCART, RCA composite or S-Video. This selection brings together an RGB SCART output from a JAMMA supergun for arcade boards and a 1.8 m three-RCA composite AV cable for the Wii and Wii U, two opposite ways of getting an analogue picture back.

RGB SCART or composite: two very different picture qualities

RGB separates the colours, composite mixes them

A SCART socket carrying RGBS transports red, green and blue over separate wires, plus the sync. That is what a JAMMA CBOX supergun provides, used to connect an arcade board or a Neo Geo MVS to a CRT television or a scaler. At the other end, a composite AV cable bundles the whole picture onto a single yellow wire, with colour noise around the edges; that is the format of the Wii and Wii U cable with three 1.8 m RCA plugs, yellow for video, red and white for sound.

A SCART socket being present does not mean RGB is accepted

  • Television: many flat screens have a SCART socket that only accepts composite, not RGB.
  • Power: a JAMMA supergun needs a separate ATX power supply to work.
  • Controllers: the CBOX controller inputs use the DB15 format, different from home console connectors.

What it doesn't do

These cables convert nothing to HDMI: a purely digital screen will not accept them without an extra box. Composite does not become RGB by changing the cable; the quality depends on the machine's output. And a supergun does not replace a cabinet: it supplies neither a screen nor built-in controls.

Questions fréquentes

What is a JAMMA supergun like the CBOX for?
It lets you use an arcade board in JAMMA format, for instance a Neo Geo MVS, outside a cabinet. It provides the JAMMA connector, a video output in RGBS over SCART and DB15 controller inputs. Power comes from a PC ATX supply, not included with the box.
Does the Wii composite cable also work on the Wii U?
Yes, the composite AV cable on offer is intended for the Wii and the Wii U. It ends in three 1.8 m RCA plugs: yellow for video, red and white for stereo audio. On a recent TV with no RCA input, you will need to add an AV-to-HDMI converter.
Does RGB really bring a visible gain?
Yes, especially on arcade games and on text. Composite makes colours bleed and creates moire on fine patterns, because luminance and chrominance share a single wire. RGB separates the three primary colours and keeps edges sharp, provided the screen or the scaler really accepts that signal.
