Wii to SCART

From HwB

Cable for connecting Nintendo Wii to a TV with SCART connection.

This will only work on PAL Wii, since NTSC Wii doesn't output RGB.

There has been reports that NTSC Wii outputs +12VDC all the time on pin 13, instead of +6VDC for 16:9 and +12VDC for 4:3.

2.2k resistor is a good value because it doesn't draw too much current even if loaded with 10k from the SCART, the voltage doesn't fall outside of the spec.
