Abstract
A video display system is provided for a video game or the like including a computer, a CRT, and mechanism for displaying images on the CRT under control of the computer. An image memory receives image data from the computer for subsequent display on the CRT. A mechanism causes the image data to be written into the image memory in one of two selectable modes, namely, left to right or right to left. Another mechanism causes the image data to be read from the memory for subsequent display on said CRT in one of two modes, namely, top to bottom or bottom to top. A mechanism controls the selection of the writing and reading modes wherein the image displayed on the CRT may be normal or inverted when viewed from a fixed position.
