*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:

Some AV cables have different internal components between regions:
| Console | Signal | PAL | NTSC |
|---|---|---|---|
| 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.
