If you grew up in the late 1980s, Nintendo’s Demovision Game Boy Kiosk may look familiar, as nearly every electronics store had one. You might be wondering how it works, and the short answer is that the kiosk used WideBoy, or a peripheral that allowed developers to test handheld games on a CRT screen.
The WideBoy basically consists of a circuit board with all of the standard Game Boy parts, except for the CPU, made by “Intelligent Systems co.ltd.” What you might not know is that it uses the Famicom / NES for power, while custom hardware feeds an 8k RAM chip with a CHR version of the Game Boy’s screen. Now if the BIOS were to crash, or the reset button is pressed, the actual Game Boy console keeps on running.

The most interesting part here is that this particular unit was updated to display a Game Boy Pocket as opposed to an original Game Boy. You can see how the plastic housing surrounding it is designed for the larger model,” said one commenter.
