The original Nintendo Game Boy, model number DMG-01, is one of the most important machines in the history of play. Launched in 1989, the grey brick with the pea-green screen went on to sell in the tens of millions and defined portable gaming for a generation. This guide is the starting point for the whole DMG-01 story: what it is, how it works, and where to go next for the detail.

Everything below links to a full article in the Journal, so you can start broad and dive as deep as you like.
Where It Came From
The Game Boy did not appear from nowhere. It was the product of a card company that had reinvented itself many times over, and of one designer's philosophy of doing more with less. Start with the story of the DMG-01, then read how a hanafuda card maker became Nintendo and why Gunpei Yokoi's "lateral thinking with withered technology" made the handheld possible. If you want the arrival itself, see the games that launched the Game Boy.
The Hardware Itself
Take the original apart and you find engineering tuned for one goal: reliable, affordable, all-day play. Our anatomy of the DMG-01 walks through the design, and if you have ever wondered about that unmistakable look, we explain why the Game Boy screen was green.
Colours and Regional Variants
For six years the Game Boy came in one colour, then it bloomed. See every DMG-01 colour variant explained and the striking European clear and colour collection. Hardware also changed subtly by market: our guide to Japanese, European and US Game Boys compared lays out the differences.
Reading the Codes
Turn almost any Game Boy over and you will find a code. Two guides unlock them: decoding the DMG model numbers, and the plain-English glossary of the abbreviations every collector should know (DMG, MGB, CGB, region tags and more).
The Companions
The DMG-01 rarely travelled alone. It reached the television through the Super Game Boy, turned into a camera and photo lab with the Game Boy Camera and Printer, and became social through a single grey wire, the story of the Game Boy Link Cable.
