The IIgs RGB decoding method will always be looking crisp and beats
everything (except mono) it terms of price/performance. :-)

Right now the NTSC table approach is impractical for the FPGA because
of the big table size, but I will try reducing them as fitting into
FPGA was one of the main goals when I started it. How many BRAMs do
you want to spare and what is the DAC resolution? BRAM in x9 width
seems practical to me, then you can have 3 bits per color component.
