I have added some notes to www.fpgaarcade.com describing how to modify the
Spartan kit board to have 12 bit RGB output on the VGA port.

Also included is some test pattern code / bitfile to produce some output.

Would it also be possible to use a solution as in XAPP154, "Virtex
Synthesizable Delta-Sigma DAC"?

The discrete part would be three caps, maybe lodged in between pins
1-6, 2-7 and 3-8? Are there readily available caps that would fit? What
would be the best value to use with the 270 Ohm resistors on the board?
