Abstract
A video game includes apparatus for scrolling playfield objects appearing on the display unit of the game. The apparatus selectively offsets the address used to access an addressable random access memory containing data indicative of the TV picture displayed. The random access data, when accessed, is used to address a video data memory which provides the building block components of the video display. Further scrolling effect is obtained by selectively delaying the video data communicated to the video display unit.
