The Supervision was a low priced competition for the Nintendo Game Boy, and came with four AA batteries, headphones and a Breakout clone named Crystball. A unique feature of the Supervision was that it could be connected to a television. Although the Supervision received some attention upon launch for its low price, it failed to beat the Game Boy as best handheld game console. The reasonsfor that were the poor quality of the screen en the lack of- & simplistic games that were released for it.
