The Dizzy series of computer games was one of the most successful computer game brands of the late eighties. They were all based around a central figure, an intelligent egg-like creature called Dizzy.
Dizzy the Adventurer is an enhanced NES port of the sixth game in the series, Dizzy: Prince of the Yolkfolk, completed fast by the use of creative routes and of course, maximum speed.
There is also a run of the second game in the series, Treasure Island Dizzy.
