This would be awesome. Pinouts anyone? What about audio? Can you get it from the audio jack straight into scart?
It's actually a rather simple cable to make. The SCART and VGA pinouts (amongst tons of others) can be found at
The Hardware Book.
Just connect the obvious pins together with the exception of at the VGA side connect the HSYNC pin to the SCART composite in pin and the VGA VSYNC pin to the SCART blanking signal pin via a 75 Ohm resistor. The audio is easier, just buy a regular jack to jack audio lead, cut one end off and wire it to the SCART audio in pins.
