-The Dreamcast connector is a wild, multi-functioned beast.  It offers several outputs in the default configuration (composite and s-video), and can output two kinds of 15kHz RGB, as well as VGA, when the proper mode is selected.

-==== Usage Notes ====
-The select pins are 6 and 7.  Ground either one for two kinds of 15kHz RGB, ground both for VGA.  **Note** that the Dreamcast outputs VGA, the box or cable does not 'upscan', so Dreamcast VGA boxes cannot be used for converting low-res RGB to VGA on other consoles.
-You should use a 220uf capacitor on each of the RGB lines (+ towards console).
-Note!! Please note that some of games will not run with a VGA box, or with the RGB/SCART mod. Most do, however.
-When the mode selection pins are used certain signals are enabled or disabled:-
