    video-decoder proms added for Defender,Stargate,Robotron,Joust,Sinistar,
    Bubbles, etc. by HIGHWAYMAN, all decoder proms are 512x8.
    defender original pcb's used a single prom(decoder1).
    newer defender pcb's used 2 proms(decoder2,decoder3) this was to allow
    video inversion for the coctail table, decoders 1 & 2 are the same code.
    white was first romset, then green/blue the only difference was the chips used,
    the final version was red, only red can run in a coctail table.
    (red also has *much* improved enemy AI and is harder to play)
    Colony7 uses a different chip for decoder2(cs10), but decoder3 is the same.
    early stargate pcb's used decoder4, and decoder5.
    newer stargate pcb's and the other games on that hardware used decoder4 and decoder6
    this was probably just to fix a minor bug in decoder5.
    Blaster uses decoder4 and decoder6 and 2 other proms.
    if i could find more proms i would clean this up into a table - maybe later.

    Blitter (Stargate and Defender do not have blitter)
    ---------------------------------------------------

    CA00 start_blitter    Each bits has a function
          1000 0000 Do not process half the byte 4-7
          0100 0000 Do not process half the byte 0-3
          0010 0000 Shift the shape one pixel right (to display a shape on an odd pixel)
          0001 0000 Remap, if shape != 0 then pixel = mask
          0000 1000 Source  1 = take source 0 = take Mask only
          0000 0100 ?
          0000 0010 Transparent
          0000 0001
    CA01 blitter_mask     Not really a mask, more a remap color, see Blitter
