One of the earliest Nintendo products to gain popularity was the Game and Watch product line. Produced by Nintendo between 1980 and 1991, they are a source of nostalgia for many an 80s or 90s kid. These were those electronic handheld games that had pre-drawn monochrome images that would light up to make very basic animations. [Andrew] loved his old “Vermin” game as a kid, but eventually he sold it off. Wanting to re-live those childhood memories, he decided to build his own Game and Watch emulator.
The heart of [Andrew’s] build is a PIC18F4550 USB demo board he found on eBay. The board allows you to upload HEX files directly via USB using some simple front end software. [Andrew] wrote the code for his game in C using MPLAB. His device uses a Nokia 5110 LCD screen and is powered from a small lithium ion battery.
For the housing, [Andrew] started from another old handheld game that was about the right size. He gutted all of the old parts and stuck the new ones in their place. He also gave the housing a sort of brushed metal look using spray paint. The end result is a pretty good approximation of the original thing as evidenced by the video below.
