(In some later Space Invaders derivatives, such as Taito's Space Invaders Part II of 1979, this circuit is a Fujitsu MB14241, a single-chip implementation of the barrel shifter.) Midway's version increased the size of the character sprites, while at the same time restricting each character's movement to their respective portions of the screen. Nishikado believed that his original version was more fun than Midway's version, but he was impressed with the Midway machine's improved graphics and smoother animation.
