On the VGA connector pins 6, 7 and 8 are just connected to GND. While this is simpler to show on the design you may want to comment that by connecting the pins as followed will simplify implementation. VGA pin 6 - SCART pin 13, VGA pin 7 - SCART pin 9 and VGA pin 8 - SCART pin 5, as these are the respective GND. Pin 5 on the VGA can also be connected to the capacitor from pin 13 as this is the Hsync GND.
