>From the project description:

"So the way to go was then to bypass the chrominance/luminance signal
generation of the VIC-II and make a solution that computes a YPbPr
signal directly from the digital information available inside the
computer. As it turns out, it is enough to passively listen to just
about 22 pins of the VIC-II to figure out what video signal it actually
intends to generate. Using the information from these pins and some
logic implemented in an FPGA, a pixel-perfect replication of the video
image can be generated."

Michau.
