Game Boy

The Joyplus Handy Boy (SV-907) is one of the most curious accessories made for the Game Boy. It was built as an all-in-one answer to the most common complaints about the handheld. The unit clips onto the console and adds a magnifying lens for the screen, two lamps to make up for the missing backlight, and stereo sound through two built-in speakers.

It needs no batteries of its own, drawing power directly from the Game Boy through a clever cable connection. Boxed examples have become hard to find, which makes the Handy Boy a notable item for accessory collectors.
