Dreamcast VGA mod
The image on a TV is always a little too blurry for my taste, and the
quality of a VGA image is very superior.
I had always dreamed to be able to use my SNES on a PC monitor, but
the SNES did not have a VGA output. When I learned that the Dreamcast
could output a VGA signal, I installed a VGA connector on it almost
How it works
Simple. The dreamcast can output VGA from it's A/V output it the rigth pin
is connected to ground. This is usually done by a VGA box.
I found the pinout of the A/V connector and a schematic for a VGA box. Instead
of building the circuit in an external box, I decided to build it inside the dreamcast.
- VGA Connector (High Density DB15, Male)
Here is the schematic:
I got it on this site:
I have been asked a few times one which side should the negative pin of the capacitors
go. They must be on the VGA connector side. The same rule apply for the S-Video output.
I used 1N4148 diodes.
