*CSYNC/Composite Sync is replaced by +12V on PAL SNES and PAL Gamecube consoles (But not the PAL N64)
Not all signals are available on all systems:
|Signal||AV Famicom||SNES||SNES2||N64||GameCube NTSC||GameCube PAL|
Some AV cables have different internal components between regions:
|SNES||Composite Video||75ohm resistor to ground on Composite Video||Straight through to display|
|SNES||S-Video||Outputs S-Video but cable components (if any) are unknown at this time||Straight through to display|
|SNES||RGB||75ohm resistors to ground on R, G, B and Composite Video||220uF Capacitors* in series on R, G & B|
|N64||Composite Video||75ohm resistor to ground on Composite Video (and 220uF capacitor* in series is also recommended)||Straight through to display|
|N64||S-Video||75ohm resistor to ground and 220uF capacitor* in series on Luma. 75ohm resistor to ground and 68nF capacitor in series on Chroma||Straight through to display|
|N64||RGB||Requires modification first - Only a certain early French model - 'NUS-001(FRA)' - can be modified easily. Any cable components will depend on the mod performed||Requires modification first - Only early NTSC consoles can be modified easily. Any cable components will depend on the mod performed|
|Gamecube||Composite Video||75ohm resistor to ground and 220uF capacitor* in series on Composite Video||Straight through to display|
|Gamecube||S-Video||Does not output S-Video from the MultiAV port||Straight through to display|
|Gamecube||RGB||220uF Capacitors* in series on R, G & B. If you are going to watch/use the Composite video picture aswell (Scart connection) then you also need to use a 75ohm resistor to ground and 220uF capacitor* in series on Composite Video||Does not output RGB from the MultiAV port. RGB can be obtained from the 'Digital AV Out' port by using a modified Component/D-Terminal cable. For more info see here.|
*220uF capacitors are polarised, and it is important that the positive leg always goes towards the console and negative leg towards TV/Display.
The resistors need to be before the capacitors (going from console -> TV), otherwise the picture will be toned/tanned and will look off.
The PAL SNES was internally revised 4 or more times during its lifetime. Later consoles used a different video encoder chip and supporting circuitry and 'appear' to work fine with an unmodified PAL Gamecube/NTSC SNES Scart cable (with capacitors)
