The title screen I drew by hand, one pixel at a time. Content and Introduction Let me be honest from the start: nobody was waiting for this. The world has many needs, and a Game Boy cartridge with no game inside it was not high on the list. But I run this museum, a project that catalogues everything around the little grey machine, and one day a thought took hold that I could not shake, mostly because it made me laugh. Every object in the collection is a museum piece. So what if the museum itself became one of them? A cartridge that plays nothing, that you slot into a real Game Boy, and that turns the machine into a guide to its own world. An exhibit about the collection, living inside the collection. That is the whole reason it exists. I thought it was a funny idea, and I wanted to see if I could do it. The vast Game Boy ecosystem on one tiny cart As it happens, I was not the first person to have the daft idea of a Game Boy that does not play. Back in 1991 and 1992, Nintendo itself sold a small run of cartridges that were not games at all: a Frommer's travel guide, Berlitz translators, a calculator, an address book. The collection keeps seven of these curious little reference carts, from a brief moment when the most famous toy in the world moonlighted as a pocket assistant. So this is really me continuing a tradition, thirty years late and with a much narrower subject: the Game Boy, explaining itself. InfoGenius did it before - carts that do not play anything A museum you can hold Switch it on and there are no sprites, no levels, no music to speak of, which I realise is a strange thing to be proud of. What you get instead is the collection itself, reached from one plain menu: Topics, Catalogue, Search, Bookmarks. You can page through 355 objects, sorted into their categories exactly as they are on the gameboymuseum.com website, reading each one's story a screen at a time. Alongside them I put a small wiki, a proper little encyclopedia of the Game Boy's world that you read chapter by chapter like a paperback: it opens with Origins and Anatomy, works through The DMG Series and its Add-ons, travels Around the World, meets The Makers behind the machine, tours the Games and Studios, and closes with an Afterlife and a Reference section. There is a search that runs across the whole lot, and I was careful with one small thing: even an everyday word like game, which appears in almost every entry, still returns its long, honest list rather than pretending it found nothing. A reference that goes quiet on an obvious word feels broken, and I would rather it be too eager than a liar. There are also Bookmarks, so you can star the objects you are still hunting for, and the cartridge keeps them in its battery for the next time you switch it on, just the way an old save file used to hold your progress. It runs on a real Game Boy, and if you do not have one to hand, it runs just as happily in a browser. The Game Boy does not want to be a book Here is the joke I walked into: a Game Boy is a spectacularly bad e-reader, and it fought me at every turn. The machine can only show 255 little building blocks on screen at once, the tiny tiles it was designed to stack into Marios and mushrooms. Text is greedy with them, because once letters have different widths nearly every line becomes a unique arrangement, and suddenly a page of plain words devours the same budget a whole level of graphics would. My compromise is eight lines of about thirty characters, and the wordiest page in the entire cartridge scrapes in at 251 blocks out of 255. Four to spare. Reading a museum on a Game Boy, it turns out, is a game of inches. Even picking a typeface became a small comedy, because on a screen this coarse a font is only as good as its worst letter. One candidate mashed its lowercase m into an n, so number came out as nunber and Game as Gane. Another could not tell c from o, turning screen into soreen and colours into oolours. A third looked crisp and handsome and then turned out to have no lowercase letters at all. The winner was a humble, freely shared pixel font that stands seven pixels tall with a single pixel hanging below the line, which comes to exactly eight, the precise height of one of those stubborn little tiles. Sometimes the right answer is simply the one whose m survives. How to draw a face without making a skull The only picture in the whole cartridge is a small portrait of me, tucked into the credits, and it caused more trouble than anything made of words. The Game Boy sees the world in four shades of green, and two of the lighter ones sit so close together that if you simply squash a photograph down to those four tones, everything bright collapses into a single flat colour. The face becomes one pale blob, the eyes turn into two black holes, and you have accidentally drawn a skull. It is not a flattering way to introduce yourself. The fix is the same sleight of hand the old Game Boy Camera used. Rather than judging the photo against the greens, you sort it into even bands of grey first and hand out the colours afterward, and you check the result in plain grey too, because on that cheerful green screen a bad picture can look deceptively fine. Even the background needed thought, since a large flat area only stays smooth in a couple of the available tones and breaks into speckles everywhere else, which is why I ended up sitting on a deep, dark backdrop rather than a soft mid-grey. The same photo, tuned in grey until it stopped looking like a skull A code the Game Boy was never meant to show Of everything in the cartridge, the part that makes me grin most is the QR codes, because by rights they should not be here at all. When the Game Boy was born in 1989, the QR code did not yet exist. It would not be invented until 1994, and it was created to track parts on a Japanese car-factory floor, not to appear on a monochrome handheld. The Game Boy was never designed to show one, and it certainly was never meant to become a link to a website that would not arrive for another decade. There is something I find quietly wonderful about bolting a piece of the mid-nineties onto a machine from the eighties so it can talk to a phone from today. Making it work meant deciding where the work should happen. The Game Boy could build a QR code on the fly, as Jason Compton of "This Week in Retro" kindly pointed out to me: homebrew coders have done exactly that on machines running the Z80, a close cousin of its processor. But there is no reason to, because every link on the cartridge is known before it ships. So nothing is generated live on the console. Instead I render every one of the 355 codes in advance on a PC and bake them into the ROM, ready to appear the instant you open an object. There was a fiddly visual catch too: draw the code a shade too large and it dissolves into a mess of one-off tiles that blows the 255 budget again, so each code is sized to snap neatly onto the tile grid and is built from only sixteen repeating pieces. And because a QR code baked onto a cartridge can never be corrected once it leaves my hands, each one points not at a catalogue number, which I might reshuffle one day, but at an object's permanent identity, so the code on the shelf will always lead somewhere real. Point your very modern phone at this very old screen and it jumps straight to the full entry, photographs and all, on the website. The small stubborn details The title screen I drew by hand, pixel by pixel, and then coaxed into the cartridge until the machine reproduced it exactly. An earlier, grander version, a whole museum hall with display cases and spotlights, was simply too detailed for the Game Boy to hold, so the screen that greets you now is the leaner, prouder one that actually fit. And yes, there was the obligatory lost evening, the kind every project like this seems to demand, when the whole thing booted to a blank white screen and told me nothing until I finally cornered the cause. That is rather the point of building on hardware this old: it makes you earn every screen, and it does not hand out participation trophies. So no, the world did not need this, and I make no claim that it did. But I keep coming back to the small joy at the centre of it: a museum object that is itself a museum. Download and browser emulation The ROM is free to download, and it runs straight in a browser too, but the version I care about is the one on a real Game Boy. It is a homage to the machine, and a small attempt to keep this knowledge where it came from in the first place, on the Game Boy itself, so that whatever happens to websites and servers and me, the little grey brick can still tell you its own story. You can pick it up over at The GB Museum on a cartridge. How it grew This page has grown along with the cartridge. Here is the short version of how it got here. December 2025: the idea, and a first stubborn attempt at text. Spring 2026: the catalogue, straight from the collection. Summer 2026: the wiki, chapter by chapter, one search across both, and a QR code on every object. September 2026: 1.0, the first public release, with bookmarks kept in the cartridge battery. Since: scrolling titles, a quiet click, a settings page, and every article pointing to the next one. Nintendo had tried turning the Game Boy into a tool first; the whole story is in the InfoGenius saga. The reference cartridge is one of several the museum has built to run on a real Game Boy, alongside the GB Test Lab, which checks whether a console still works, and Label Boy, which turns the Game Boy Printer into a label maker.

By the middle of the 1990s, many people had quietly written off the Game Boy. It was monochrome in an age of colour, ancient by console standards and seemingly out of road. Then a game about collecting little creatures arrived and changed everything. Pokemon did not just sell well. It reached back and gave an ageing handheld a whole second life. A Dying Handheld By 1996 the Game Boy was seven years old. Its colour rivals had already come and gone, Nintendo's attention had moved to 32-bit machines, and the handheld looked like yesterday's technology. Few in the press expected much from yet another Game Boy release, and on paper the timing for a brand-new role-playing game looked terrible. An Idea Built on the Link Cable The first titles, Red and Green, came from Game Freak under Satoshi Tajiri and reached Japan on 27 February 1996. Tajiri has said the sight of two Game Boys joined by a link cable inspired the whole concept, channelling his childhood love of insect collecting into catching and trading creatures. The full origin story is told in Pokemon on the Game Boy; what matters here is what happened next. The Craze That Revived the Console The effect built slowly, then all at once. Pokemon turned the link cable from a novelty into the heart of the experience, because you simply could not catch them all alone. That social hook, plus cheap cartridges children could actually afford, sent sales climbing long after launch. When the games reached the West as Red and Blue in 1998, they arrived alongside an anime, a trading-card craze and playground legends like the infamous MissingNo glitch, making Pokemon the defining childhood obsession of the late 1990s. Game Boy hardware sales, long past their supposed peak, climbed to new records. Colour, and a Second Generation Pokemon did not just extend the old Game Boy, it led the charge into the next one. When the Game Boy Color launched in 1998, Pokemon was its standard-bearer, and in 1999 Pokemon Gold and Silver added a hundred new creatures and a built-in clock, keeping the magic going for years more. A franchise born to rescue a dying handheld ended up powering its successor too. Pikachu Everywhere Nintendo knew exactly what it had. Special Pokemon-themed consoles, the yellow Pikachu Game Boy among them, and a wave of Pikachu-branded accessories followed the games into shops. The whole range is catalogued in Pikachu's hardware. Collecting Pokemon on the Game Boy For collectors, the early Pokemon cartridges are milestones: the Japanese Red and Green, the later Yellow Special Pikachu Edition, and their international cousins. They mark the exact moment a humble grey handheld refused to fade away. Browse the whole Pokemon corner of the collection, or read the bigger picture in Pokemon and the Game Boy.

After more than thirty years, you might think the Game Boy holds no more surprises. It does. Behind that familiar grey shell sits a pile of genuinely strange and wonderful stories. Some facts which might suprise... Here are ten of the best, the kind of details that make collecting it so much fun, each one with the full story a click away. Ten Surprising Game Boy Facts 1. A Game Boy has been to space. In 1993 a Game Boy travelled to the Mir space station, and it is considered the first games console in orbit. The story of the Game Boy that went to space is stranger than you would guess. 2. It could find fish. The Bandai Pocket Sonar turned the Game Boy into a working sonar fish finder, recognised as the first sonar peripheral for a games console. 3. The green screen was an accident of economy. That pea-green look came from a cheap, reflective LCD with no backlight, chosen to keep the price and battery use low, as explained in why the Game Boy screen was green. 4. The start-up logo was a legal trap. The Game Boy checks the Nintendo logo stored on every cartridge before it will boot, so unlicensed makers had to reproduce the trademark and exposed themselves to legal action. It all rides on the famous boot sequence. 5. Its killer app came from the USSR. Tetris, bundled with the Game Boy in the West, was invented by Alexey Pajitnov in the Soviet Union. 6. It sold in staggering numbers. The monochrome Game Boy and the Game Boy Color together sold a combined 118.69 million units worldwide. 7. It held a world-record camera. The Game Boy Camera was certified by Guinness World Records in 1999 as the world's smallest digital camera. 8. You could play with barcodes. The Namco Barcode Boy let you scan barcodes, even from supermarket packaging, to create and battle characters. 9. Mario's handheld debut had no Miyamoto. Super Mario Land was made by Gunpei Yokoi's hardware team rather than Mario's usual creator, which is why it feels so unusual. 10. Japan had game downloads in the year 2000. Through the Nintendo Power cartridge service you could write Game Boy games onto a blank cartridge at a convenience-store kiosk, long before digital stores existed. More Than a Toy Every one of these facts points to the same thing: a simple grey handheld that people kept stretching into something bigger, stranger and more enduring than anyone expected. It is exactly that depth that makes the original Game Boy so rewarding to collect.

Great hardware still has to be sold, and few products were sold as cleverly as the Game Boy. Across the late 1980s and 1990s, the advertising around Nintendo's handheld shifted in step with the console itself, and those old adverts are now a fascinating record in their own right. F1 Advertisement for the Game Boy (DMG-01) The collection holds a deep archive of period print advertising, and together it tells the story of how the Game Boy was pitched to the world. Early Advertising: Freedom and Tetris At launch, the message was simple: take your games anywhere. Early Game Boy advertising leaned hard on portability and on its killer pack-in, Tetris, the puzzle everyone could enjoy. The tone echoed Nintendo's famous line, now you're playing with power, reworked for a machine you could carry in a pocket. The promise was freedom: gaming on the bus, in the garden or in the back seat, and a game so universal that parents played it as happily as their children. Game Boy Tetris Bundle Advertisement Play It Loud: A Rebellious Rebrand By 1995, with the hardware ageing, Nintendo changed its tune. The Play It Loud! campaign repositioned the Game Boy as bold and a little rebellious, matching the new range of brightly coloured shells with louder, edgier advertising aimed at older players. It was a clever way to keep a six-year-old machine feeling fresh and cool rather than dated. Pokemania on the Page By the end of the 1990s the message changed again. With Pokemon turning the ageing handheld into a phenomenon, the advertising followed the craze, selling the Game Boy to a brand-new generation on the promise of catching and trading creatures. The story of that revival is told in how Pokemon gave the Game Boy a second life. Toughness as a Selling Point Nintendo also leaned on the Game Boy's legendary durability. The most famous example is real: a Game Boy pulled from a bombed barracks during the Gulf War, charred and blistered, that still switched on and played Tetris. That scorched survivor became a lasting symbol of how rugged the machine was, a story told in full in Famous Survivors. Tie-Ins and Regional Flavour The adverts also reveal how differently the Game Boy was sold from country to country, and how it rode big cultural moments. The collection includes everything from straight console ads in the UK, Germany and Italy to game tie-ins such as a Star Wars advertisement, plus adverts for the third-party accessories that surrounded the system. That market-by-market variety is explored in Region by Region. Read together, they map the Game Boy's journey from new gadget to cultural fixture. Why Game Boy Advertising Is Worth Collecting Original Game Boy advertising is social history on a single page: the slogans, the art and the attitudes of the time, all captured in print. Magazines were read and thrown away, so clean surviving ads are scarcer than the games they promoted, and they add real context to a hardware collection. Browse the wider archive in the collection.

Long before every phone had a camera, Nintendo managed to turn a games console into one. The Game Boy Camera and its companion, the Game Boy Printer, briefly made the humble DMG-01 one of the most charming imaging devices on the planet. It was lo-fi, monochrome and gloriously silly, and for a lot of people it was the very first digital camera they ever held. The Game Boy Camera Released in 1998, the Game Boy Camera slotted into the cartridge port and added a swivelling lens that could spin right round for self-portraits. Behind that lens sat a 128 by 128 pixel sensor that captured tiny 128 by 112 images in the Game Boy's four shades of grey. In 1999 Guinness World Records certified it as the world's smallest digital camera. It came in several bright shell colours, from yellow and green to red and blue, with rarer special editions sold only in Japan. Hidden Depths The Camera was far more than a lens. Tucked inside were stamps, drawing tools and warping effects, a run of silly mini-games, and, most surprisingly, a full little music sequencer that let you compose tunes over animated backgrounds. That hidden studio has its own cult following among chiptune musicians, who still coax strange sounds out of a twenty-five-year-old toy camera. Tiny Prints: The Game Boy Printer A digital photo is more fun when you can hold it, and that is where the Game Boy Printer came in. This little thermal printer connected through the link port, ran on six AA batteries and produced stamp-sized prints on rolls of sticky-backed thermal paper. It was never only for the Camera, either: Pokemon games printed Pokedex entries and party photos, and a surprising number of other titles learned to send something to paper. Which ones still work on an original DMG-01 is its own small puzzle, explored in Games That Print. A Real Camera for Pocket Money What made the system remarkable was the price. The camera cost around fifty dollars at launch, at a time when a proper consumer digital camera could run to a thousand. That gulf put digital imaging in the hands of children and quietly challenged the idea that photography had to be expensive. In Japan it sold close to half a million units in its first three weeks alone. The Printer's Second Life The Game Boy Printer has aged better than almost any accessory. Its thermal paper and simple protocol are well understood today, so people connect it to computers, print modern pixel art and give it jobs Nintendo never imagined. Here at the museum we built our own cartridge for exactly this, LABEL BOY, which finally lets you type your own text and print real labels on the printer. And if you are curious about the machine itself, see exactly how the Game Boy Printer works. Why the Game Boy Camera Endures Decades later the Game Boy Camera has a devoted following. Artists still shoot whole projects on it, enthusiasts have even used it to photograph the night sky, and its dreamy low-resolution look feels deliberately stylish in a world of flawless phone photos. For collectors, a complete camera and printer set is a delightful corner of the DMG-01 story. Explore more context in the Knowledge Base.

There was a particular thrill, in the school playground of the 1990s, to knowing the right code. Punch in a string of letters and numbers, and a game that had beaten you for weeks would suddenly hand you infinite lives. The devices that made this magic possible were the cheat cartridges. On the Game Boy, two names ruled this grey area: the Game Genie and Action Replay. The Game Boy Game Genie The Game Genie was the work of the British studio Codemasters, sold in North America by Galoob and elsewhere by Camerica. You slotted your game into the Game Genie, then slotted the Game Genie into the Game Boy. On power-up, a menu let you type in alphanumeric codes, which the device used to alter the data passing between the cartridge and the console, effectively reprogramming the game on the fly. A couple of face buttons let you switch codes on and off or jump back to the code screen. The most famous Game Boy Cheat device: Game Genie The Lawsuit That Made Cheating Legal Nintendo hated these devices and took the fight to court. In the early 1990s it sued Galoob over the Game Genie, arguing that altering a game created an unauthorised derivative work. Nintendo lost. A US court ruled that the Game Genie simply changed how a game played for the owner's own enjoyment, much like fast-forwarding a film, and broke no copyright. That verdict effectively made cheat devices legal and opened the door for everyone that followed. Action Replay and the Cheat Wars The Game Genie was not alone. Datel's Action Replay did much the same job and sat at the head of a whole family of rival brands such as GameShark and Code Breaker. There was a real technical split between them: where the Game Genie patched the data coming off the cartridge, devices like the Action Replay and GameShark worked on the console's memory directly, continuously forcing values such as lives or health to stay where you wanted them. That let them do tricks the Game Genie could not, including hunting for brand-new codes on the device itself. For players, the choice often came down to which code lists you could get hold of in magazines and on early websites. Game Boy Cheat Device: Action Replay Pro Reprogramming on the Fly What made these devices clever was the pass-through trick. By sitting between the cartridge and the Game Boy, they could intercept and tweak small pieces of data as the game ran, changing values like lives, health or starting level without ever touching the cartridge permanently. Whole communities sprang up around finding and sharing new codes, and magazines devoted pages to them. It was an early, grass-roots form of game modding. Why Game Boy Cheat Devices Are Collectible Although they were unlicensed and a little mischievous, the Game Boy Game Genie and its rivals are now nostalgic icons in their own right, often remembered as fondly as the games they bent. Complete examples with their chunky code books are a fun, characterful addition to a collection. The cartridge slot turned out to be full of these hidden tricks: the cheat and memory modules are catalogued in Hidden Powers, Part 5, or explore more peripherals in the Knowledge Base.

The original Game Boy was built to be played anywhere: on the bus, in the back of a car, under the covers long after bedtime. So there is a lovely irony in one of its most beloved accessories doing the exact opposite, pulling the handheld out of your hands and putting it on the family television. That accessory was the Super Game Boy, and for a whole generation it was the first time their pocket games appeared in colour, on the big screen, in the middle of the living room. What the Super Game Boy Did Released in 1994, the Super Game Boy is not a console but a clever cartridge. Slot it into a Super Nintendo, drop a Game Boy game into the top, and the handheld's whole library suddenly runs on your TV through the SNES. It reached Japan on 14 June 1994, North America that July and Europe in September, and it instantly changed how families experienced the original Game Boy. The Classic Super Game Boy How It Actually Worked The trick is simpler than it looks. Inside the Super Game Boy adapter sits a complete Game Boy, the same processor and sound hardware as the handheld, plus a special chip that hands the picture to the Super Nintendo. The SNES does the rest: it takes the Game Boy's plain four-tone image, paints it in colour, wraps it in a border and sends the whole thing to your television. In effect you are playing a real Game Boy, with a Super Nintendo acting as its screen, its speakers and its colouriser. Colour, Borders and Hidden Tricks Because the Game Boy screen shows only four shades of green, the Super Game Boy maps those shades to real colour. Players could pick from built-in palettes or mix their own and save them with a password, and the adapter could paint the screen in up to twelve colours at once. Around the playing field it added decorative borders drawn from a palette of up to sixty-four colours. Developers who knew the adapter was there could do more still: a game could load its own palette the instant it booted, carry a bespoke border, and even play extra Super Nintendo sounds and music that a real Game Boy could never produce. Donkey Kong is the showcase, with its own frame, richer colours and SNES-quality audio flourishes. The Super Game Boy 2 In January 1998 Japan received a refined sequel, the Super Game Boy 2. Its headline addition was a link port, added in direct response to Pokemon players who could not trade because the first model had nowhere to plug in a link cable. It also ran at the exact speed of a real Game Boy, where the original had run slightly fast, and shipped with eight fresh borders. It never left Japan, which makes it a prized import today. Super Game Boy 2 with Link Cable Port From Pocket to Big Screen The Super Game Boy was also the first time Nintendo answered a simple wish: to play handheld games on the television. It would not be the last. Years later the Game Boy Player did the same job for the GameCube, and today emulators and capture devices do it on any screen. The whole story is told in playing Game Boy games on your TV. Why the Super Game Boy Still Matters The Super Game Boy turned a monochrome handheld into a shared, colourful living-room experience, and quietly previewed the colour future the Game Boy Color would deliver in 1998. For collectors, both versions are essential pieces of the DMG-01 story, and the Japan-only sequel is a genuine prize. For the bigger picture, see the complete guide to the original Game Boy, or where it sits in the DMG-01 hardware reference.

Some consoles are remembered for their hardware. The Game Boy is remembered, as much as anything, for a single falling-blocks puzzle that came free in the box. Tetris and the Game Boy arrived together, and together they conquered the world. It is hard to overstate how unlikely that pairing was: a Soviet puzzle, a determined Dutch-born publisher, a tangle of Cold War rights, and a little grey handheld from Kyoto. A Puzzle from Moscow Tetris was created in 1984 by Alexey Pajitnov, a software engineer at the Dorodnicyn Computing Centre of the Soviet Academy of Sciences in Moscow. He built it in his spare time on an early Soviet computer, and its simple, hypnotic rhythm of falling tetromino shapes was so addictive that colleagues reportedly stopped working to play it. Copies spread from machine to machine, then out of the Soviet Union entirely, long before anyone had worked out who actually owned it. That question would take years, and several lawsuits, to answer. The Rights War Because Tetris escaped into the world before its rights were settled, a tangle of companies ended up claiming pieces of it across computers, consoles and arcades. The knot was finally cut by Henk Rogers, a game designer and publisher who spotted Tetris at a Las Vegas trade show in 1988. Knowing the Game Boy was coming, he pitched it to Nintendo as the perfect pack-in, then flew to Moscow to negotiate directly with the Soviet state body ELORG. He came away with the crucial handheld and console rights, outmanoeuvring Atari, whose rival console version was pulled after a court fight. The full, almost unbelievable story is told in The Tetris Story: From Moscow to the Game Boy. Everywhere Except Japan One detail often surprises people: the Game Boy was only bundled with Tetris in the West. In Japan the console launched in April 1989 with no pack-in at all, and Tetris arrived separately that June. It was Nintendo of America that turned the pairing into a bundle, and it changed everything. More on those market-by-market differences in Region by Region. The Bundle That Built an Empire Bundling Tetris with the Western Game Boy was a masterstroke. Where Mario mainly appealed to younger players, Tetris appealed to everyone: commuters, parents, students, people who had never called themselves gamers. A puzzle with no reading, no violence and no learning curve was the perfect ambassador for a new kind of machine. It turned the handheld from a toy into a mainstream habit, and Game Boy Tetris went on to sell more than thirty-five million copies, a huge share of the console's overall success. Two Players, One Cable Tetris also gave the Game Boy's link cable its first real reason to exist. Join two consoles together and Tetris became a head-to-head duel, with cleared lines dumped onto your opponent's screen. A quiet little puzzle became a competitive sport on playgrounds and trains, and the cable that had seemed like an afterthought suddenly mattered. The Song Everyone Knows Then there is the music. The Game Boy's main Tetris theme, an arrangement of the Russian folk tune Korobeiniki, is one of the most recognisable pieces of video-game music ever written, hummed by people who have never held a Game Boy. It even escaped onto the pop charts in the 1990s. Why Game Boy Tetris Still Matters For collectors, Game Boy Tetris is the cornerstone cartridge, the game that explains the entire platform in one neat grey shell. A complete, boxed copy belongs in any serious DMG-01 collection, and it remains one of the most recognisable video games ever made. See the original console where it all began in the collection.

On paper, the original Game Boy should have lost. It was grey, monochrome and technologically modest, while its rivals arrived in dazzling colour. And yet the little Nintendo handheld did not just win, it buried the competition. How it did so is one of the clearest lessons in the history of gaming: cheaper, simpler and longer-lasting can beat bigger and brighter. To see why, it helps to put the machines side by side. The Colourful Challengers The Game Boy did not launch unopposed. The Atari Lynx, released in 1989, was the first handheld with a colour LCD, a genuinely impressive machine with a backlit screen and hardware sprite scaling that made Nintendo's grey brick look primitive. Sega's Game Gear followed in 1990, also in colour and backlit, essentially a portable version of the Master System console. A third contender, NEC's TurboExpress, arrived in 1990 as a pocket version of the TurboGrafx-16. All three looked like the future sitting next to the Game Boy, and all three carried the same hidden bill. Sega's Game Gear (1990) The Specs, Side by Side Line up the raw numbers and the Game Boy looks outclassed on almost every row that sounds impressive. Colour, bigger and backlit screens, more capable graphics: its rivals had them all. What the table also shows, though, is the hidden price of that power. Feature Game Boy (1989) Atari Lynx (1989) Sega Game Gear (1990) Screen 2.5-inch reflective LCD 3.5-inch backlit LCD 3.2-inch backlit LCD Colour 4 shades of grey Colour Colour Batteries 4 x AA 6 x AA 6 x AA Battery life around 15 to 30 hours about 3 to 5 hours about 3 to 5 hours Launch price (US) about $90 about $180 about $150 Approx. units sold well over 100 million a few million around 10 to 11 million The Price Nobody Mentions Start with the sticker. The Game Boy launched at around ninety dollars. The Game Gear asked roughly a hundred and fifty, the Lynx closer to a hundred and eighty, and the TurboExpress a startling two hundred and fifty. For a parent buying a gift, or a child saving pocket money, that gap alone settled a lot of arguments before anyone switched a machine on. Cheaper hardware also meant Nintendo could sell far more of it, which in turn drew the developers and the games. Why the Colour Rivals Fell Short Then came the hidden cost of colour: power. Both the Lynx and the Game Gear were larger, heavier and astonishingly thirsty, draining six AA batteries in roughly three to five hours. The Game Boy ran for close to fifteen hours or more on four, and shrugged off a life of being carried everywhere. For a device meant to be portable, that difference was decisive: a colour screen is worth little when the machine is dead by lunchtime. The same toughness is why so many survive and still switch on today. Atari's Lynx (1989) The Tetris and Library Advantage Hardware was only half the battle. Nintendo bundled Tetris with the Game Boy in the West, a game with near-universal appeal that sold the console to people who had never bought a game before, and backed the system with a deep, steadily growing library and strong third-party support. The colour rivals never assembled a catalogue that could compete, and no amount of extra colours could make up for a shortage of games people actually wanted to play. Lateral Thinking with Withered Technology None of this was an accident. The Game Boy's designer, Gunpei Yokoi, followed a philosophy he called lateral thinking with withered technology: take cheap, mature, well-understood components and use them cleverly, rather than chasing the newest and most expensive parts. Choosing a monochrome, non-backlit screen was not a failure of ambition but a deliberate trade, buying low cost, long battery life and durability at the price of colour. It is the same decision that gave the console its famous green screen. The Lynx and Game Gear made the opposite bet, and the market punished them for it. What Became of the Challengers The market delivered its verdict quickly. The Lynx never found a foothold and Atari quietly wound it down by the mid-1990s. The Game Gear did better, but Sega moved on, and it faded before the decade was out. The TurboExpress barely registered outside Japan. The Game Boy, meanwhile, kept selling for years, outlived all of them, and was still being made long after its rivals were discontinued. Winning the Handheld Wars The result was not close. The Game Boy line went on to sell well over a hundred million units, while the Game Gear managed something in the order of ten million, the Lynx only a few million, and the TurboExpress fewer still. Decades later the lesson still holds: accessibility, battery life and great games beat raw specifications. See where it all began in the DMG-01 hardware reference.

The Game Boy did not come from a chase for the most powerful chips or the sharpest screen. It came from a philosophy, and from one quietly brilliant engineer who believed that old, cheap technology used cleverly could beat the cutting edge. That engineer was Gunpei Yokoi, and his ideas shaped not just the Game Boy but the way we hold a controller to this day. Who Was Gunpei Yokoi Gunpei Yokoi, born in 1941, joined Nintendo in 1965, when it was still largely a playing-card company, and at first his job was simply to maintain the machines on the factory floor. His first hit came almost by accident: a simple extending-arm toy called the Ultra Hand that he had been tinkering with on his workbench. It sold in the millions and turned a maintenance engineer into Nintendo's first great toy designer. A string of playful inventions followed, from the Love Tester to the Beam Gun light-gun series, and each showed the same instinct: finding fun, original uses for ordinary, inexpensive technology. Lateral Thinking with Withered Technology Yokoi summed up his approach in a memorable phrase: lateral thinking with withered technology. Rather than reaching for the newest and most expensive components, he favoured mature technology that was well understood, cheap to produce and reliable, then found clever new things to do with it. The pay-off was not only a lower price but fewer surprises, because proven parts rarely fail. The Game Boy is the purest example, modest hardware brilliantly applied, and it is exactly why it outlasted far flashier rivals like the Atari Lynx and Sega Game Gear. The D-Pad and the Game & Watch Yokoi's fingerprints are everywhere in how we play. For the Game & Watch handhelds, the pocket LCD games he launched in 1980, he devised the cross-shaped directional pad, the D-pad now found on almost every controller made since. It was a tiny, elegant solution to a hard problem: how to move in four directions with one thumb, flat enough to fit a device the size of a credit card. The idea jumped straight onto the NES controller and never left. You can see the Game & Watch legacy live on in Game & Watch Gallery on the Game Boy itself. Mentor, and a Run of Classics Yokoi did not work alone, and part of his genius was spotting talent. In the early 1980s he mentored a young artist named Shigeru Miyamoto, guiding him through the making of Donkey Kong. Through Nintendo's R&D1 group, Yokoi also oversaw landmark games of his own, including Metroid and Kid Icarus. Few people in the industry can claim a fraction of that influence over both how games are played and what they contain. The Game Boy, His Masterpiece When Yokoi led the creation of the Game Boy in 1989, every lesson of his career came together: cheap, rugged, long-lived hardware, a clear idea of fun, and the confidence to ignore the specification race. The result sold in the tens of millions and defined handheld gaming for a decade. The full story of that machine is told in the complete guide to the original Game Boy. The Virtual Boy, and Leaving Nintendo Not every bet paid off. Yokoi's final Nintendo project, the Virtual Boy of 1995, promised 3D but delivered eye strain and weak sales, and it is often tied, fairly or not, to his departure the following year. He left to found his own company, Koto Laboratory, and designed one more handheld, the WonderSwan, for Bandai. He did not live to see it released: Gunpei Yokoi died in a road accident in 1997, at just fifty-six. Why Gunpei Yokoi Still Matters His thinking never went away. Every thumb resting on a directional pad, and every handheld that values battery life and playability over raw specifications, carries a little of his philosophy. Even the Nintendo Switch, with its focus on fun over firepower, is Yokoi's idea wearing modern clothes. To see his most famous creation in context, explore the Knowledge Base.

Close your eyes and picture the original Game Boy in action, and you almost certainly see it: that murky, pea-soup green, with dark grey-green dots crawling across it. It is one of the most recognisable looks in all of gaming. But why green, of all colours? The answer is a neat little mix of physics, cost and common sense, and it tells you a lot about how the Game Boy was designed. Classic Game Boy Green Screen with Tetris The Game Boy Green Screen, Explained The colour came from the screen technology itself. The Game Boy used a reflective, super-twisted nematic (STN) liquid crystal display, and the combination of its reflective and polarising layers gave the panel a natural greenish tint. Nintendo did not paint the screen green; that hue was simply what this particular, affordable display produced. The panel shows just four shades, from a pale grey-green to a near-black, and every image on the machine, from Mario to Tetris, is drawn in those four tones alone. The STN panel also had a better viewing angle than the alternatives, a sensible trade for a device you hold at all sorts of angles. Its one real weakness was speed: STN crystals are slow to switch, which is why fast movement smeared and ghosted across the screen. Cheap, Reliable and No Backlight This fits perfectly with the philosophy of designer Gunpei Yokoi, who prized cheap, mature, reliable technology. A reflective LCD with no backlight was far less expensive and used far less power than fancier alternatives. Instead of lighting the screen from behind, it simply reflected whatever light was already in the room, which costs nothing at all. That single decision is a big part of why the original Game Boy ran for many hours on four AA batteries while its colour rivals, the Atari Lynx and Sega Game Gear, drained their cells in an afternoon. The Catch: You Had to Find the Light The no-backlight choice had an obvious downside: in a dim room, or under the covers at night, you simply could not see the picture. A whole small industry grew up to solve it, from clip-on worm lights that bent over the top of the console to magnifying visors that clamped to the front. See the story of the lights and magnifiers players used to chase that one good angle. Nintendo itself only answered the problem late, with the backlit, Japan-only Game Boy Light in 1998. Easier on the Eyes There was a human factor too. Nintendo's own studies suggested that green tones were relatively easy on the eyes, and a slightly greenish background gave the clearest contrast for the dark dots that made up the picture. So the colour that fell out of the cheap display also happened to be comfortable to stare at for hours. Necessity and comfort lined up neatly. When the Green Went Away The famous green did not last the whole Game Boy story. When Nintendo shrank the console into the Game Boy Pocket in 1996, it fitted a new reflective display that showed crisp black and white instead of green, with far better contrast. When colour finally arrived with the Game Boy Color in 1998, the green vanished for good. It turned out to be a quirk of the 1989 panel, not a deliberate house colour, which is exactly why, to collectors, the green screen belongs specifically to the original DMG-01. More on the panel itself in the hardware series on the screen. Why the Game Boy Green Screen Became Iconic What began as a practical compromise became an identity. The Game Boy green screen is now instant visual shorthand for an entire era, lovingly recreated in emulators, art and merchandise. Modern restorers can even swap the original panel for a bright backlit IPS screen, and many deliberately keep a DMG-green filter so it still looks right. See how those backlight and screen mods work. For collectors, a clean, even original screen is a real prize, because that particular shade of green is the Game Boy. Dive deeper into the hardware in the DMG-01 hardware reference.

A grey plastic cartridge that once sat forgotten in a bargain bin can now trade for more than a decent used car. That is the strange arithmetic of Game Boy collecting, and it is exactly what keeps drawing so many of us back to the hunt. The library runs past a thousand titles, and while the great majority are common and cheap, a small handful have become genuinely hard to find. This is a tour of the ones collectors talk about, and, just as importantly, of why they command the prices they do. What makes a Game Boy game rare Rarity on the Game Boy usually comes down to a few repeating causes. The first is a small print run. Late releases that arrived as the system was fading, or games from small publishers with limited marketing budgets, simply never reached many shelves. The second is regional exclusivity. A title released in only one territory, or given a tiny run in a market that shrugged and moved on, becomes scarce everywhere else. Licensing adds another twist. Games tied to films, cartoons or bands were often printed briefly and then quietly discontinued, and once the licence lapsed they were rarely reissued. Then there are the true oddities: unlicensed curios and promotional or competition cartridges made in numbers you can count on your fingers. Layered on top of all of this is condition, which can turn an already scarce game into something extraordinary. Loose, boxed, sealed: why condition multiplies everything Before the individual games, it helps to know the ladder that collectors use. A loose cartridge is the cheapest tier. A complete-in-box copy, usually shortened to CIB, adds the box, the manual and any inserts, and that completeness alone can multiply the price. Above that sit factory-sealed copies, still wrapped from the day they left the production line, and finally professionally graded pieces, sealed in protective slabs with an authenticated score. Each rung up that ladder can add a surprising amount to the very same title, which is why you will see the same game quoted at wildly different figures. The vegetable dynasty: Amazing Tater and Spud's Adventure If collectors have a white whale, it is often Amazing Tater. Developed by Atlus, it is a late entry in a quirky block-pushing puzzle series that began with Kwirk, and it shipped with a famously small run. Loose cartridges are widely reported to sell for several hundred dollars, complete boxed examples have reached the low thousands, and pristine sealed copies have carried far higher asking prices still. Its stablemate, Spud's Adventure, sits close behind. A top-down blend of puzzle and light adventure starring a heroic potato on a rescue mission, it shares the same limited-run pedigree. Complete-in-box copies are widely reported to change hands for well over a thousand dollars, and considerably more when the condition is high. Together the two prove a simple rule of this hobby: a modest game with a tiny print run can quietly outvalue a masterpiece that sold in the millions. Licensed latecomers and regional orphans Konami's Kid Dracula, a cute spin on the Castlevania world, reached the West in modest numbers, and Castlevania collectors have been chasing it ever since. Loose carts sit in the low hundreds, while boxed copies are widely reported to climb into the low thousands. Capcom's Mega Man IV and Mega Man V tell a similar story. Both are late, well-crafted handheld entries that were not folded onto later compilations in the same way as their console cousins, so complete copies stay scarce and can command four-figure prices in good condition. Regional exclusivity does the rest. Toxic Crusaders, based on the cartoon, saw only a North American release, which makes complete copies a real headache to track down elsewhere in the world. Hammerin' Harry, an Irem platformer, is another sought-after boxed rarity that surfaces only occasionally. And F1 Pole Position, in its North American Black Label form, is a collector favourite for an almost absurd reason: a small print run combined with a quirk of the box art turned an otherwise ordinary racing game into a prize. Promotional and competition curiosities Some of the rarest carts were never sold in shops at all. Promotional giveaways, competition cartridges and tiny commemorative runs sit at the very edge of the hobby, made in numbers so small that most collectors will only ever see them in photographs. A recent example shows the pattern perfectly: to mark an album anniversary, a band released a run of just twenty-five playable Game Boy cartridges, and a single sealed copy went on to sell for thousands of dollars. Here the scarcity, not the gameplay, is the whole story. Sealed, graded, and the Pokemon effect There is a second route to a valuable Game Boy game, and it has little to do with how few were made. Take a common, beloved title, keep it factory-sealed, have it professionally graded, and the numbers can turn startling. Sealed and highly graded copies of games as ordinary as Super Mario Land, Tetris and the early Pokemon releases have sold at auction for thousands, and the very finest examples have reached figures high enough to make headlines. The game inside is the same one that once sold by the million. What buyers are really paying for is preservation and proof. A graded version of Super Mario Land (CGC 9.0) Pokemon deserves its own mention. The franchise pulls a huge, worldwide audience into cartridge collecting, and that demand lifts prices for sealed and graded copies far above what scarcity alone would justify. It is a useful reminder that value is never just about supply. Demand, nostalgia and the confidence that a grading slab provides all push in the same direction, and when they line up behind a famous title the results can be spectacular. A serious word on value All of this comes with a large caveat. Prices in the retro market move, sometimes sharply, and a figure quoted today may look very different a year from now. Condition and grading change everything, so a loose cart and a sealed, graded copy of the same game can sit thousands of dollars apart. Reported sales are snapshots rather than fixed values, and a single unusual auction can distort the picture for months. The hardware has its own grails: see the rarest and most valuable consoles and hardware. So treat every number here as a rough historical range rather than a price tag, and never as financial advice. We document these games because they are fascinating pieces of history, not because anyone should view them as investments. If you want to understand the mechanics behind all of this, our feature on what makes a Game Boy valuable goes deeper into rarity, condition, completeness and demand. The rarest Game Boy games endure because they tell a story about how a beloved system was made, sold and remembered, from a limited-run puzzler to a sealed classic that never left its wrapper. You can explore much more of that story across the Game Boy Museum. Beyond the games themselves, see the rarest pieces in the collection.
