+^ N64 | RGB | Requires modification first - Only early French consoles can be modified easily. Any components will depend on the mod performed | Requires modification first - Only early NTSC consoles can be modified easily. Any components will depend on the mod performed |

+^ Gamecube | RGB | 220uF Capacitors* in series on R, G and B lines. If you are going to watch/use the Composite video aswell (Scart connection) then you also need to use a 75 ohm resistor to ground and 220uF capacitor* in series on the Composite line| Does not output RGB from the MultiAV port|
+*220uF capacitors are polarised, and it is important that the positive leg always goes towards the console and negative leg towards TV/Display.
+The PAL SNES was internally revised 4 or 5 times during its lifetime. Later consoles appear to have had different video circuitry and may actually work fine with an unmodified PAL Gamecube Scart cable (with capacitors) The best thing to do is to try an unmodified cable first, and then remove the capacitors/add resistors if need be.
+According to [[mailto:jchristy@hplred.HP.COM|Jim Christy]], the US and NTSC SNES have a 'DC offset', which is basically extra voltage, on the RGB lines (1v DC according to Jay Tiltons site). You can filter this out with one 220uf capacitor on each of the RGB lines (+ towards console, - towards display).  PAL SNES systems do not need these caps, but may require some 47 ohm resistors in their place in order to get the video contrast down to the correct level.  PAL GameCubes need the caps, NTSC GameCubes don't output RGB through this connector.
+Actually, there appears to be different PAL models with different RGB output. In my case, I had an RGB SCART cable designed for GameCube (I popped the SCART connector open, and there were resistors on the RGB pins). I also had two machines: "SNSP-001(SCN)" (PAL, Scandinavian model) and "SNSP-001A(FRG)" (PAL, Unknown origin, possibly French or German, guessing by the "FRG"). The SCN model did NOT work with the GameCube RGB SCART (picture became close to completely dark after a few seconds), while the FRG model works perfectly with the "capping" GameCube SCART.
+For reference, [[http://www.gamesx.com/misctech/mypin.htm|here's the pinout]] I use to connect all my systems to my monitors. A single common pinout means I don't need a seperate monitor cable for each system.

+Here is the pinout for the [[nintendodigitalav|GameCube Digital AV]] port.
+<box round warning 40% |PAL Users Note:>The PAL SNES and PAL Gamecube (But not the PAL N64) outputs +12v on pin 3, not composite sync (C-Sync).  This is for a SCART TV to automatically detect RGB input.  See the [[av:scart_connector|SCART pinout page]] for more details.  Thanks to [[mailto:mark_k@iname.com|Mark K.]] for this info.  </box>
-Some interesting info from [[mailto:jchristy@hplred.HP.COM|Jim Christy]] about the AV outputs: As seen below, the SNES does have RGB capability. I was able to get a stable raster on my NEC MultiSync "classic" using the RGB and sync pins. However, the video levels are not RS-170 compatible. The DC offset needs to be filtered out with some large capacitors and the peak-to-peak video amplitude may need to be reduced to 0.7v by using a lower load impedance than 75 ohms."  Now, what this means to you and I is something else entirely. See the [[http://www.gamesx.com/rgbadd/caveatrgb.htm|RGB Caveats]] for more details on RGB output usage. For reference, [[http://www.gamesx.com/misctech/mypin.htm|here's the pinout]] I use to connect all my systems to my monitors. I single common pinout means I don't need a seperate monitor cable for each system.
-Also note: These pinouts are also valid for the Nintendo 64 console, except for the RGB and sync lines, which aren't present in the N64. For info on adding RGB to a Nintendo 64, [[http://www.gamesx.com/rgbadd/n64rgb.htm|see here.]]
-Also note: the new style SNES does not output RGB or S-video either. [[http://www.gamesx.com/rgbadd/snes2rgb.htm|See here for more info.]]
-PAL users note: A PAL SNES outputs +11v on pin 3, not composite Sync. This is for a SCART TV to automatically detect RGB input. Thanks to [[mailto:mark_k@iname.com|Mark K.]] for this info.
