- | In this diagram (and, it should be noted, the official Nintendo RGB lead), SCART pin 8 (aspect ratio switching) is permanently connected to 12V. This will tell TVs that listen to this signal that the aspect ratio of the picture is 4:3 (as any signal between 9.5V and 12V will). If you have a suitable TV and want it to work at 16:9 by default, this pin needs to be brought down to between 4.5V and 7V (6V nominal). A voltage divider should probably be used for this purpose, but a single resistor will also probably work with a bit of information about the probable internal resistance to gnd of SCART pin 8.

NB: Since I wrote this, I have discovered that other experimenters are reporting that this pin does NOT alter its voltage in units of several regions - the conjecture is that it will ONLY operate as expected in Japanese units where the D-terminal cable is used. |
