"This ROM set has been made available with the consent of its co-author,
Larry DeMar.

ConquestA.ROM loads at $0000-$8FFF
ConquestB.ROM loads at $D000-$FFFF

Being an early prototype, these ROM images have a large amount of empty space.

CMOS is at $CC00-$CFFF, but it appears to expect 8-bits rather than the usual
4-bit CMOS for a Williams game.

Architecture is similar to Robotron (including interrrupts, raster counter,
etc.) but doesn't use a blitter.

Unique PIA functions:

$C804: Bit 0 = Fire
Bit 1 = Thrust
Bit 2-3 = Bits 2-3 of encoder wheel
Bit 4 = 2P Start
Bit 5 = 1P Start

$C806: Bits 0-1 = Bits 0-1 of encoder wheel
Bit 7 = Cocktail (unused)

The prototype appears to use the Defender's sound ROM.

Game play:

Basic game play has a ship that moves in a 2D scrolling world with scanner,
similar to Sinistar. Rotate, shoot and thrust. Destroy "Planets" while
avoiding or destroying their hums. A wave ends when all planets are
destroyed. There is no attract mode implemented so the ROM simply displays
a solid colour-shifting background until 1P Start or 2P Start is pressed.

I played it on the browser. Using a keyboard to play.
