Abstract of the Disclosure A method and apparatus for generating moving objects for a video game display. Common apparatus in- cluding a microprocessor with RAM provides vertical motion for all objects and separate horizontal position counting hardware horizontal motion for each object. The micro- processor operating on a horizontal line pair basis drives a parallel to serial converter which stores one eight bit line portion of the object to be displayed which in turn is connected to a shift register. When the converted data is read out to the video display by action of the appropriate horizontal postion hardware, it is recirculated to provide a repeat on the next horizontal line of the identical data. An effective one line moving resolution is obtained by utilizing another shift register for a one line delay by means of switch which is set by a latch driven by the microprocessor.
