The newest arrival in this series raises an obvious question. Super Mario Land is already in the collection, and it is one of the most common games on the entire platform, so why add another copy at all? The answer is condition, and what condition can preserve. Perfectly preserved, permanently unplayable. A 9.0 that will never hear a single bleep. What It Is This is a United States copy of Super Mario Land, professionally graded and encapsulated by CGC with an overall grade of 9.0. It is certified complete in box, with individual sub-grades of 9.0 for the box, 9.8 for the cartridge and 8.0 for the manual, and it carries the label's designations for an early production run. Most charming of all, it still wears its original period price sticker from the American retailer Electronics Boutique, a small paper survivor that fixes the game to a specific shop and a specific moment in the early nineties. Why It Was Added Grading turns a common cartridge into something a collection genuinely needs: a reference specimen. A loose, well-played copy tells you what the game was; a sealed, third-party-authenticated 9.0 tells you exactly how it left the factory, preserved and independently verified. For one of the console's defining launch-era titles, having a benchmark example on hand is valuable in its own right, both as a preservation standard and as an anchor for understanding what condition really means when values are discussed. That verification is not just a promise printed on a label. The CGC case carries a QR code, and scanning it resolves to this exact certification in CGC's own database, listing the item, the grade and the certification number. Anyone holding the slab can therefore confirm in seconds that the label belongs to this game and has not been reprinted or swapped. In a hobby where convincing reproductions are a genuine problem, that verifiable chain back to the grader is the part of the whole exercise that does real work. The surviving shop sticker adds a second layer of history that a pristine but sticker-free copy would lack. It is a tiny piece of retail archaeology, evidence of how and where the game was actually sold, and exactly the kind of detail that turns a graded slab from a mere investment piece into a documented artefact. That combination, top-tier condition plus a preserved point-of-sale trace, is why this particular copy earned a place alongside the collection's existing Super Mario Land. A Deliberate Exception to Our Complete-in-Box Focus It is worth being clear about where this piece sits, because it runs against the grain of how the collection is built. This museum deliberately specialises in complete-in-box games rather than sealed or graded ones, a choice explained in full in Sealed, Slabbed or Complete-in-Box: Why We Chose CIB. A complete-in-box game can be handled, studied and displayed as the object its makers intended; a slab, sealed behind plastic, cannot. This graded Super Mario Land is therefore a conscious and single exception, not a change of direction. The intention is to hold exactly one professionally graded specimen of the two most renowned grading services each - WATA and CGC. Simply so that the grading and rating scene, which has become a real and growing part of the wider Game Boy collecting movement, is represented and acknowledged here. One slab honours that world; the rest of the collection remains firmly complete-in-box. The Wata half of that pair has since arrived as well, a factory-sealed InfoGenius Personal Organizer graded 8.5, which completes the pair and closes the subject. This graded copy is fully catalogued, with photographs, on its own page in the collection.

In the last few years, retro games have turned into an asset class. Sealed, professionally graded cartridges now change hands for staggering sums, sometimes more than a house deposit, sealed forever inside a numbered acrylic case. It is an extraordinary shift, and it forces every serious collector to make a choice about what they are really collecting. The Game Boy Museum made its choice deliberately, and it went the other way. The Rise of the Sealed and Slabbed Game Grading works by taking a game, judging its condition against a strict scale, and sealing it in a tamper-proof case with that score printed on the label. Borrowed from the world of trading cards and coins, it has swept through retro gaming and created a booming market. A high grade can multiply a game's price many times over. For sellers and investors, it has been a gold rush. What Grading Genuinely Offers It would be unfair to dismiss it entirely, because grading does solve real problems. An independent grade offers reassurance against fakes and reproductions, which are a genuine plague in this hobby. The sealed case protects a fragile old box from further wear. And a recognised score makes buying and selling at a distance far less risky, because both sides trust the same standard. For a certain kind of collector, that certainty and protection is exactly what they want. However, as this trend is itself part of Game Boy history now, the museum keeps two graded pieces of its own. One is a CGC 9.0 Super Mario Land, a complete-in-box US printing whose cartridge scored 9.8 and whose manual, tellingly, scored 8.0. The other is an InfoGenius Personal Organizer, factory sealed and graded by Wata at 8.5 with a B+ seal. Both are here precisely because the grading trend has become part of the Game Boy's story, and a museum that documents the object should also document what the market is now doing to it. Look closely at either slab and you will find the part that actually does the work: a machine-readable code printed on the label. The CGC case carries a QR code, the Wata case an EAN barcode, and each one resolves to that specific certification in the grader's own database, listing the item, the grade and the certification number. Scan it and you can confirm in seconds that the slab in front of you is the one the label claims to be, and that nobody has swapped the contents or reprinted the label. In a hobby where convincing reproductions are a real problem, this is the genuinely useful part of the whole exercise: not the number itself, but a verifiable chain back to the company that assigned it. And What It Quietly Takes Away But look closer and something is lost. A slabbed game can never be opened, so its manual can never be read, its inserts never unfolded, and the cartridge never played. The object becomes a picture of itself, valued only for a number on a label. Worse, as prices climb, ordinary games are bought purely to be sealed and speculated on, pulling them out of the hands of the very people who love them. Piece by piece, the machine that was built to be carried everywhere and played by everyone is being locked away where no one can touch it. That is the money machine that makes retro history inaccessible. Why the Game Boy Museum Collects Complete-in-Box The museum's answer is the complete-in-box game, known as CIB. A CIB item has everything that originally came with it: the outer box, the manual, any inserts and registration cards, and the cartridge itself, all present and correct. It is complete, it is honest about its condition, and crucially it is openable. You can take out the manual and read it. You can slot the cartridge into a real Game Boy and play it. You can study the printing, the inlays and the little details that tell you where and when it was made. The object stays alive. The Game Boy Museum Approach: Complete-in-box: everything that came in the box, and still openable. Preservation Should Not Mean Locking Away A museum exists to keep things safe and to make them understood, and those two goals have to be held together. A CIB collection lets us do both: preserve the full artefact while still learning from it and sharing it. A wall of sealed acrylic might be worth more on a spreadsheet, but it teaches nothing and gives nothing back. We would rather protect the Game Boy as what it always was, a thing to be handled, understood and enjoyed, than freeze it into a silent investment. You can explore the collection, complete and openable, right here in the collection.

Learn to build your own simple game The Game Boy is not only a treasure to keep behind glass. Decades after it launched, it is still a living platform that anyone can create for, and you do not need to be a professional programmer to begin. On this site we have written two hands-on series that, together, take you all the way from an empty folder to a polished game of your own, running on a real 1989 console. Both are written for complete beginners, with every single line of code explained in plain English. This page is the map that ties them together. Series One: Build Your Own Game Boy Game The first series is where everyone should start. Over six short parts you install the free tools, learn how the Game Boy actually draws (it thinks in little tiles, not pixels), and then build a complete, playable Snake in the C language, step by step. Create your first Game Boy game - the basics You give it a playfield and walls, make the snake move to your button presses, add food, growth and a way to lose, and finally run your finished ROM in an emulator or on a genuine Game Boy. By the end you have written a real game from nothing. TOPICS: Part 1: Setting Up Your Workshop Part 2: How the Game Boy Thinks Part 3: Drawing Your World Part 4: Taking Control Part 5: Food, Growth and Game Over · Part 6: From Emulator to Cartridge Series Two: Level Up Your Snake The second series picks up exactly where the first leaves off and turns that bare Snake into a rounded little game with its own character. Let's add some flavour to the game in part II You learn how graphics were really made for the Game Boy and design your own font and start screen, then add an interactive title screen, a live score, three lives, a proper game-over screen, and finally sound effects and a pause button. Along the way you meet the ideas behind every real game: reusable functions, loops, keeping track of numbers, and talking to the sound hardware, all at a gentle pace. TOPICS Part 1: Drawing Graphics the Game Boy Way Part 2: A Title Screen for Your Snake Part 3: Keeping Score Part 4: Three Lives Part 5: A Proper Game Over Part 6: Sound and Pause Who It Is For, and What You Need Both series are aimed squarely at people with little or no coding experience. There is no jargon left unexplained, and every code block is followed by a plain-language walk-through. The tools are all free and run on Windows, macOS and Linux: the GBDK-2020 development kit, any text editor, and an emulator such as Emulicious, BGB or SameBoy to test your game. That is genuinely all you need to follow along. If you later want to play your creation on real hardware, a flash cartridge like an EverDrive lets you run it on an original DMG-01, which is a magical moment worth chasing. Where to Start If you are new, begin with Series One, Part 1 and work through in order; by the end you will have a working Snake. Then move on to Series Two to give it a title screen, a score, lives, an ending, sound and pause. If you have already built the Snake and just want to make it feel finished, you can jump straight into Series Two. Either way, take it one part at a time, type the code in yourself rather than only reading it, and enjoy the moment your own game lights up that green screen. And whenever you want inspiration, the games that built this machine are all here to study and admire in the collection.

No game is more tangled up with the Game Boy than Tetris. It was the cartridge in the box, the reason millions of people bought the console, and one of the best-selling video games ever made. But behind that clean, falling-blocks simplicity lies one of the strangest and most litigious stories in gaming, a tale that runs from a Soviet computer lab to the courtrooms of the West and finally into the box of a Nintendo handheld. Here is the whole story: where Tetris came from, the rights battle that nearly buried it, the trivia around it, and the sequels it spawned on the Game Boy itself. Probably the most recognized home screen for the Game Boy - Tetris (1989) Born Behind the Iron Curtain Tetris was created in 1984 by Alexey Pajitnov, a researcher at the Soviet Academy of Sciences in Moscow. He built it as a side project, and it spread from computer to computer across the country on copied floppy disks, with no thought of profit, because under the Soviet system the state, not the programmer, owned the work. That single fact, that Tetris belonged to the USSR rather than to its creator, is the root of everything that followed. The Rights Battle As the game leaked westward it was licensed, sublicensed and mislicensed in a hopeless tangle. A businessman named Robert Stein believed he had secured the rights and passed them on to Western publishers, who in turn sold console and arcade versions to companies including Atari, all before anyone had cleanly established what the Soviet authorities had actually agreed to. The USSR's trade body, known as Elorg, had never signed away the rights everyone assumed they held, and the whole edifice was built on sand. Stand alone version of Tetris - Complete in Box The decisive move came from Henk Rogers, who flew to Moscow and negotiated directly with Elorg. He secured the crucial handheld rights for Nintendo, which is why Tetris could be packaged with the Game Boy, and Nintendo went on to nail down the console rights too. That triggered a bitter legal fight with Atari's Tengen over its unofficial NES version: the courts sided with Nintendo, and Tengen was forced to pull its cartridges from sale, reportedly destroying tens of thousands of them. The Game That Sold the Console Bundling Tetris with the Game Boy in the West was a masterstroke. A simple, language-free puzzle that anyone could grasp in seconds turned the handheld into a device for everyone, not just for children or dedicated gamers. Commuters, parents and grandparents bought a Game Boy because they wanted to keep playing Tetris, and it went on to sell in the region of 35 million copies on the console alone. It remains the clearest example in history of the right game selling the right hardware. The Trivia The story is full of remarkable footnotes. For years Pajitnov earned nothing from his own creation, because Elorg held the rights; only in the mid-1990s, once the original licences had lapsed, did control finally revert toward its creator, and in 1996 he and Henk Rogers formed the business that became The Tetris Company, still the guardian of all things Tetris today. The game's very name blends the Greek prefix for four, reflecting its four-block pieces, with tennis, Pajitnov's favourite sport. And the specific version bundled with the Game Boy is the one that fixed Tetris in the popular imagination worldwide, above all the countless other editions. The Game Boy Successors Success on that scale demanded sequels, and the Game Boy got several. Tetris 2, released here bundled with a golden console, mixed the falling blocks with colour-matching and connecting mechanics for a different, more deliberate kind of puzzle. It was followed by further variations such as Tetris Blast, which added explosive bombs to the formula, Tetris Plus, with its puzzle-adventure mode, and Tetris Attack, a fast tile-swapping game that carried the Tetris name in the West despite being a different design underneath. Together they show how Nintendo tried, again and again, to bottle the original's lightning. Why Tetris Anchors a Collection Every serious Game Boy collection revolves around Tetris, and rightly so. It is the commercial cornerstone of the whole platform, the game most responsible for its success, and the carrier of a history that stretches from Cold War Moscow to modern licensing. To hold the Game Boy Tetris cartridge is to hold the single most consequential object in the console's story, and the sequels that followed it map the platform's long attempt to recapture a once-in-a-generation phenomenon. The Tetris cartridge and its Game Boy successors are documented, with their packaging where complete, in the collection.

Long before amiibo figures and toys-to-life games, Nintendo's handheld already had a way to pull real-world objects into a game. All you needed was a barcode, and a strange little device called the Barcode Boy. It is one of those ideas that sounds made up, and yet it was a real, boxed product you could buy in 1992. What Is the Barcode Boy? The Barcode Boy was developed by Sofel and released by Namcot, a Namco brand, only in Japan in December 1992. It connects through the Game Boy's link port, and a card is swiped through its sensor so the device can read the barcode printed on it. In effect, it gave the Game Boy a barcode scanner. Scanning the Supermarket Here is the part that delighted players: it did not only read the special cards in the box. You could scan barcodes from ordinary store-bought packaging too, turning a tin of food or a magazine into game data. Each code unlocked characters, items or features, so a trip to the supermarket became a hunt for the most powerful barcode you could find. Battles by Barcode Around four games were built to use it, the best known being Monster Maker: Barcode Saga and Battle Space. In Monster Maker, two players could enter barcodes and then fight head to head, with the codes determining each fighter's hit points, magic points, attack, defence and experience. Your shopping, quite literally, set your stats. A Truly DMG-01-Only Device There is a neat hardware footnote here. Because the Barcode Boy relies on the original Game Boy's link port, and the Game Boy Pocket introduced a different connector in 1996, the Barcode Boy is one of the rare accessories that only works on the DMG-01. It is a true original-hardware exclusive. Set 1, Set 2 and the Stand-Alone Unit The collection holds the Barcode Boy across its forms. The two boxed releases, Barcode Boy 1 and Barcode Boy 2, each paired the scanner with a compatible game and a deck of printed barcode cards to get players started. Alongside them sits a stand-alone unit, the scanner preserved on its own. Seen together, they show how Namcot packaged the same clever idea in more than one form for the Japanese market. There is a nice reason the gadget felt so futuristic at the time. In the early 1990s barcodes were the quiet symbol of a newly computerised world arriving in everyday shops, and the notion that a toy could read them, turning a cereal box into a game character, felt like genuine science fiction. That is exactly the spirit the Barcode Boy captured, and a big part of why it still charms people today. Why the Barcode Boy Endures The Barcode Boy quietly predicted a whole genre, the toys-to-life and scan-to-play games that would become huge decades later. As a Japan-only curiosity that depends on the original Game Boy, it is a wonderful talking point in any collection. Explore more peripherals in the Knowledge Base.

The Game Boy played games, of course. But for a few years in the 1990s, accessory makers were convinced it should do everything else as well, and that included playing the radio. A small group of add-ons clipped onto the handheld and turned it into a portable FM radio, and they are some of the most charming oddities in the accessory world. A Radio in Your Game Boy The best known of these is the GameTunes Stereo FM Tuner, made by the accessory specialist Beeshu. It was a true FM radio that drew power and a home from the Game Boy, letting you tune in to stations through headphones. By most accounts it worked perfectly well, which is more than you might expect from such an unlikely mashup of console and transistor radio. GameTunes and the Gameball The GameTunes tuner was not alone. The collection also holds the BigBen FM Gameball, another take on the same idea from a different maker. Between them they show that putting a radio on a Game Boy was not a one-off joke but a small genre of its own, with rival companies offering their own spin on the concept. The Era of Add-on Everything FM tuners belong to a wonderful moment when the Game Boy was treated as a platform to build on, not just a toy to play. The same shops sold clip-on lights, magnifiers, amplifiers and cradles, all promising to make the handheld brighter, louder or more capable. A radio attachment was simply the logical extension: if you already carried a Game Boy everywhere, why not let it keep you company with music too? Why the Game Boy FM Radio Add-ons Are Fun to Collect Because they were niche, third-party and easily lost, Game Boy FM radio attachments are uncommon today, and they make a delightful talking point in a collection. They capture a very particular flavour of 1990s optimism, when a grey handheld seemed like it might be the one gadget you needed for everything.

For its first six years, the Game Boy came in exactly one colour: a sober off-white grey that made it look more like a pocket calculator than a toy. Then, in the mid-1990s, Nintendo decided the grey brick should show off. It relaunched the hardware in a range of bright colours, and one model stole the show completely: a version with a clear case that let you stare straight into the machine's electronic heart. European coloured Game Boy DMG-01 collection When the Game Boy Learned to Show Off The idea arrived in 1995 with Nintendo's Play It Loud campaign, a deliberate attempt to make an ageing handheld feel fresh and fashionable again. Instead of new hardware, Nintendo simply gave the existing DMG-01 a wardrobe of new coloured shells. The consoles were identical inside, but suddenly the Game Boy came in a spectrum of finishes that turned a functional gadget into a statement. In Europe the range grew into the colourful family the museum now groups as its Limited Edition colour series. It is worth stressing that nothing changed under the plastic. Every one of these coloured Game Boys is still a standard DMG-01, with the same directional pad, A and B buttons, Start and Select, the same unlit green dot-matrix screen and the same four AA batteries. The magic was entirely on the outside, which is exactly why they are so collectible: they are pure design, the same beloved machine wearing seven different outfits. The Clear Game Boy: See-Through Star of the Set The undisputed favourite is the clear Game Boy, officially called High Tech Transparent and nicknamed the "X-Ray" in the United Kingdom. Its see-through housing reveals the green circuit board, the ribbon cable to the screen and the little speaker inside, turning the console into its own display piece. Transparent electronics were a mid-1990s craze, and see-through Game Boys have remained among the most sought-after variants ever since. The transparent shell was a hit on both sides of the Atlantic. Alongside the European unit, the collection also holds the North American Play It Loud clear console, letting you compare the same see-through idea as it was sold in different markets. There is something fitting about a museum piece you can literally see inside. Play It Loud Series - X-Ray Version (USA) That fascination was not unique to Nintendo. The mid-1990s were the golden age of see-through consumer electronics, from clear telephones to translucent stereos, all trading on the thrill of showing off the technology inside rather than hiding it. Nintendo clearly liked the effect, because it returned to transparency again and again in later years, with clear Game Boy Color shells and translucent controllers becoming recurring collector favourites. The clear DMG-01 was where that story started for the Game Boy. Every Colour in the European Run The clear model has plenty of company. The European colour series in the collection also includes the Radiant Red, the Gorgeous Green, the Deep Black, the Vibrant Yellow, a Traditional White and the Cool Blue. Seven finishes, one shelf, and a small rainbow of Nintendo history. Not every colour is equally easy to find, which is part of the fun for collectors. Yellow, red, clear and black were the common ones, produced in large numbers. Green is noticeably scarcer, while blue and white are the true rarities: the blue console was sold only in Europe and Japan, and the white was largely a Japanese release that reached Europe in limited numbers. Assembling the whole set, as here, is far harder than it looks. The colour range also threw up some intriguing regional quirks. The clear model that Europeans and Americans knew as High Tech Transparent was nicknamed the "X-Ray" in the United Kingdom, and Britain even received an exclusive red console decorated with Manchester United branding for football-mad fans. These little regional variations are catnip for collectors, because they turn a simple colour choice into a map of how Nintendo tailored the same machine for different markets. The Rarest - Traditional White Same Machine, Different Skin The Play It Loud consoles are a lovely lesson in how much personality a simple colour change can add. The internals never varied, yet a transparent shell feels futuristic, a red one feels sporty and a black one feels grown-up and serious. Nintendo understood that the Game Boy had become a personal object, something people carried everywhere, and that letting owners pick a colour made the machine feel like theirs. It was branding at its cleverest, extending the life of a console that was already a runaway success. There is a preservation angle, too. Coloured and especially transparent plastics can discolour over the decades, with clear shells yellowing and bright whites turning cream as the material reacts to light and air. A crisp, unclouded example is therefore far scarcer than the original production numbers suggest, and keeping one in good condition is a small act of conservation in its own right. It is one more reason the coloured Game Boys are prized well beyond their humble origins as a marketing refresh. The Colour Set in the Collection Seen together, the European colour run tells the story of a company that knew exactly how beloved its little handheld had become. The clear model may be the star, but each shade has its own character and its own rarity. You can explore the full spread of coloured consoles, and the rest of the DMG-01 world, across the collection.

By 1990 the Game Boy was famous enough that it started turning up in places far beyond the toy shop: on lunchboxes, on breakfast cereal, and, most surprisingly of all, on the shelves of comic-book stores. For a brief moment the little grey handheld was not just a machine you played, but the star of its own comic book, a genuinely bizarre four-issue series that remains one of the strangest artefacts in all of Game Boy history. Nintendo Comics System Game Boy comic The Nintendo Comics System The comic was part of the Nintendo Comics System, a line published by Valiant Comics between 1990 and 1991. At a time when Nintendo could do almost no wrong, the company licensed its characters out to comics that adapted its biggest games into panel-by-panel adventures. Titles based on Super Mario Bros. and other Nintendo properties filled the racks, aimed at the enormous audience of children who already spent their pocket money on the games themselves. These were unmistakably products of their era, brightly coloured and cheerfully commercial, designed to keep Nintendo's characters in front of fans between game releases. Most have been half-forgotten, which is exactly why holding the originals today feels like uncovering a small piece of buried treasure. They are a snapshot of just how completely Nintendo had captured popular culture at the start of the 1990s. The Game Boy Comic: When Sarasaland Invaded Earth The Game Boy title ran for four issues, published between June and September 1990. Despite its name, it is really a tie-in to Super Mario Land, the handheld's own launch adventure. The premise is delightfully odd: the characters of Super Mario Land, including Mario, Princess Daisy and the alien villain Tatanga, materialise out of a Game Boy and spill into the real world, turning a video game into a very physical problem for the people around it. It is a wonderfully strange conceit, and a very 1990 one. The Game Boy was still novel enough that the idea of its pixel people escaping the screen carried a genuine science-fiction charge. Rather than simply retelling the plot of Super Mario Land, the comic used the handheld itself as the doorway between the game world and ours, making the machine a character in its own right. The Game Boy comic was also part of a much larger wave. The early 1990s saw a boom in comics based on video games, as publishers raced to turn the era's biggest franchises into monthly reading. Nintendo, sitting at the very top of the industry, was the most prized licence of all, and its handheld getting a dedicated book, separate from the Mario titles, is a measure of just how big a phenomenon the Game Boy had become in barely a year on sale. Herman Smirch, the Strangest Hero in Gaming Comics At the centre of the story is not Mario but an original creation named Herman Smirch, a bitter, cynical loner who becomes tangled up with the escaped game characters. Smirch is such a sour, ill-tempered figure that the villain Tatanga finds him easy to hypnotise and bend to his will, using the man's own resentment against him. It is a surprisingly dark and psychological hook for a comic ostensibly aimed at children, and it gives the series a strange, uneasy tone that has earned it a small cult reputation among collectors. That oddness is a big part of the appeal. Where most licensed tie-ins play it safe, the Game Boy comic reads like a fever dream, blending Nintendo's colourful mascots with a downbeat human antihero. It is the kind of creative swing that simply would not be made today, which is exactly what makes the surviving issues so fascinating to leaf through. Who Made It The series was the work of writers connected to Valiant's Nintendo output. The first and third issues were written by George Caragonne, while the second and fourth were handled by Mark McClellan, both regular contributors to the wider Nintendo Comics System line. Splitting the run between two writers was common practice for these fast-moving licensed books, and it gives the four issues their own slightly uneven, anthology-like rhythm. For collectors, the distinction between a first print and a later reprint matters. The original 1990 issues are the ones that actually sat on the racks during the Game Boy's first great wave of popularity, and surviving copies in good condition are far from common, since comics of this kind were read, folded and thrown away rather than carefully preserved. Assembling all four first-print issues, as here, is a small feat of patient hunting, and it captures the series exactly as its first readers would have found it. The Four Issues in the Collection The collection holds the complete run in first print, from issue one and issue two through issue three to issue four, alongside later reprints of the same stories. Together they preserve one of the oddest corners of Game Boy history: the brief moment when the world's favourite handheld climbed off the shelf and onto the comic-book page.

Anyone can own a Game Boy. Building a true DMG-01 collection, one that captures the whole world around the machine, is a different and far more rewarding challenge. After years of doing exactly that, a few clear lessons stand out. Here is how a pile of grey bricks becomes a proper archive. Think in Categories The first step is to stop thinking about single items and start thinking in categories. A complete DMG-01 collection spans far more than consoles. It includes accessories and peripherals, the game library, official publications and catalogues, merchandise, and even period advertising and rare special items. Mapping those categories turns a vague wish to collect everything into a structured, achievable plan. Completeness and Region Within each category, completeness is where the real depth lies. That means chasing regional variants across Japan, Europe and North America, and favouring complete-in-box examples over loose parts. A matching set, correct for its market and intact down to the manuals, tells a fuller story than a shelf of mismatched pieces. Condition and Documentation Condition and documentation separate a hoard from an archive. Grading honestly, storing items safely, and recording each piece with its product code, region and provenance transforms a collection into a reference. Good records also protect value and make the whole archive useful to others, not just satisfying to own. Building a DMG-01 Collection That Lasts Ultimately, building a DMG-01 collection is an act of preservation. The goal is not just to gather objects but to keep a piece of gaming history intact and well understood for the future. That is the spirit behind this archive. Explore how it is organised in the collection, the hardware reference and the Knowledge Base.

Look in the bottom-right corner of any page on this site and you will find a small chat icon. Behind it lives GBuddy, the museum's own AI curator, and this post is a proper introduction to him. He is here to make everything we have gathered about the Game Boy easy to explore, simply by asking. GBuddy - Our little AI curator is here to help you Who Is GBuddy? GBuddy is exactly what a museum guide should be: knowledgeable, patient and focused. He is styled, fittingly, as a little Game Boy himself, complete with glasses, a bow tie, a clipboard and a Museum Curator badge. Ask him a question in plain language and he answers in plain language, whether you are a lifelong collector or someone who just found the site and is curious what all the fuss about a grey brick is. He Only Knows the Museum Here is what makes GBuddy different from a general chatbot. GBuddy draws his knowledge only from the internal database of this museum, the catalogue entries, the hardware guide and the articles in this Journal. He does not reach out to the wider internet. That is a deliberate choice: it means his answers are grounded in this collection and its documented facts, rather than in whatever a general model might have picked up elsewhere. When GBuddy tells you something, it comes from the museum itself. What to Ask Him The best way to understand GBuddy is to give him something to do. Here are a few questions to get you started, each one a doorway into a different corner of the Game Boy world: What is the difference between the original DMG-01 and the later Game Boy models? Which Game Boy games sold the most copies? What is one of the rarest pieces in this collection, and why is it so hard to find? How did people play Game Boy games on a television? What accessories were made to fix the console's unlit screen? Why was Tetris so important to the Game Boy? What should I look for to tell a genuine cartridge from a fake? Click the chat icon to say hello to GBuddy Each of those will send GBuddy digging through the museum to build you an answer, and each answer tends to suggest three more questions. That is rather the point: he is designed to turn a quiet browse into a proper conversation about the console. Why an AI Curator Fits a Museum A collection this size holds far more than anyone can take in by scrolling. GBuddy is a way to make all of it approachable, letting each visitor follow their own curiosity at their own pace instead of hunting through menus. He is not a gimmick bolted on for novelty; he is a genuine front door to the knowledge base, and the friendliest way we know to help you get lost in the Game Boy for an afternoon. So next time you are exploring the collection, say hello to GBuddy in the corner. He has been waiting to talk Game Boy with you.

Pick up almost any piece of Game Boy hardware, turn it over, and somewhere on the back you will find a short code: DMG-01, DMG-04A, CGB-P-KKK. Most people never give it a second glance. But these codes are not random at all. Nintendo ran a careful model-number system, and once you learn to read it, that little string of letters and digits tells you the console generation, the type of product, and even which part of the world it was made for. This is a guide to reading those numbers, and a tour of every DMG-numbered piece in the collection. What DMG Actually Means The story starts with the console's own development name. Inside Nintendo, the original Game Boy was the Dot Matrix Game, which is where DMG comes from, and why the console is designated DMG-01. That prefix is the first and most useful thing to read, because it marks the hardware generation. As the Game Boy family grew, each new console got its own prefix: MGB for the Game Boy Pocket, CGB for the Game Boy Color, and AGB for the Game Boy Advance. So the opening letters of any code instantly place a product in its era. A code beginning DMG belongs to the original grey brick's world. Every product carries a code: learning to read them is a collecting skill. Reading the Rest of the Code After the prefix, the rest of the code describes what the product is and where it came from. The simplest accessories were given plain sequential numbers, which is how we get DMG-01 through DMG-09. More specialised products used letter codes instead: a letter often flags the type of product, with a "P" typically marking a Game Pak, a cartridge-format product, and an "A" an accessory, followed by a short product code and then a regional suffix. Those suffixes are their own little geography lesson: JPN for Japan, USA for North America, NOE for Nintendo of Europe, and so on. Read that way, a code like DMG-A-NR-NOE unpacks neatly into a DMG-era accessory, code NR, released by Nintendo of Europe. The Simple Numbered Run: DMG-01 to DMG-09 The cleanest part of the system is the original numbered run, most of which made up the Japanese launch accessory line. It begins with the DMG-01 console itself, then runs through the DMG-02 stereo headphones, the DMG-03 rechargeable adapter, and the DMG-04 Interactive Play Cable with its shielded revision DMG-04A. From there it continues with the famously rare DMG-05 battery case and DMG-06 soft case, the DMG-07 four-player adapter, the DMG-08 cleaning kit, and the DMG-09 designation for the Game Boy cartridge itself, the standard Game Pak format every game shipped on. It is a tidy, logical sequence, and it is covered in full in the dedicated look at the Japanese box line. The Higher and Coded Numbers Beyond that first run, the numbers jump around and the letter codes take over, which is where things get interesting. The DMG-14 is the Universal Game Link Adapter, a clever bridge between the chunky original link plug and the smaller connector of later models, while the DMG-ANC belt carry bag shows even a simple pouch earned its own catalogue code. The lettered codes reveal their logic here too. The DMG-A-NR-NOE Battery Pack II is, exactly as its code says, a DMG-era accessory released by Nintendo of Europe. The DMG-P-VPH rumble pack is a Game Pak (the P), a cartridge that added vibration, most famously to Pokemon Pinball (interestingly intended for the GBC), and the DMG-P-FINC Game Boy Racing Set carries the same Game Pak marker for its bundled hardware. One of the most fascinating entries is the DMG-MMSA-JPN Nintendo Power memory cartridge, the rewritable cartridge at the heart of Japan's Nintendo Power download service, on which players could have games written to a single reusable cart in a shop. Its code marks it as a Japanese DMG-era product, but its purpose was years ahead of its time. When a Game Boy Color Game Carries a DMG Number The system also throws up a wonderful puzzle. Take the CGB-P-KKK tilt-sensor Game Pak, the special motion-sensing cartridge behind Kirby Tilt 'n' Tumble. Its product code begins with CGB, correctly marking it as a Game Boy Color title. Yet flip the cartridge over and the board itself is stamped DMG-20. In other words, a Game Boy Color game can carry an original-Game-Boy hardware number on its back. DMG-20 - The Tilt Cartridge for Kirby Pinball That apparent contradiction is actually the system working exactly as designed. The CGB code describes the product as it was sold, the game and its generation, while the DMG-20 marking describes the physical cartridge board and its hardware type. The two numbers answer two different questions, and spotting the difference is precisely the kind of detail that turns idle code-reading into genuine expertise. Why the Codes Matter to a Collector Learning to read these numbers is more than a party trick. A model code tells you at a glance which console generation a product belongs to, which region it came from, and what kind of thing it is, which is invaluable for spotting regional variants, matching an accessory to the right machine, and catching mismatched or misdescribed items. For a museum, the model number is a tiny catalogue entry that Nintendo stamped into the object itself, decades before anyone thought of it as history. Every code is a little compressed biography: a generation, a type, a place of origin, all in a handful of characters. Once you can read them, the collection stops being a set of objects and becomes a set of stories written in Nintendo's own shorthand. You can find all of these DMG-numbered pieces, and the rest of the DMG-01 world, across the collection.

When the Game Boy arrived in Japan in 1989, Nintendo did not just launch a console. It launched a whole coordinated family of accessories, each in matching packaging and each stamped with its own model number in the DMG series. Lined up together, these boxes are a beautiful sight, and completing the full Japanese line is one of the most satisfying, and most difficult, challenges a DMG-01 collector can take on. This is a piece-by-piece tour of that original box line, every item of which is here in the collection. The original Japanese Game Boy accessory family, boxed. DMG-01: The Console Itself Everything begins with DMG-01, the Game Boy console. The name is an abbreviation of Dot Matrix Game, and that model number became so iconic that collectors now use "DMG-01" as shorthand for the original grey brick itself. It is the heart of the whole system and the anchor of the entire accessory family that followed. DMG-01: The grey entertainment brick from Japan Part of the charm of this line is how coordinated it all is. Nintendo did not treat accessories as an afterthought; it gave each one a place in a numbered system and a box designed to sit alongside the others on a shop shelf. That shared visual language, the same logo, the same era of packaging, is what makes a complete run so pleasing to display. Line the boxes up and you are not looking at a pile of odds and ends, but at a single, deliberately designed product family. DMG-02 and DMG-03: Sound and Power Next come two accessories that made the machine nicer to live with. DMG-02 is the official pair of Game Boy stereo headphones, letting players enjoy the console's surprisingly rich stereo sound in private. DMG-03 is the rechargeable adapter, an official answer to the Game Boy's famous appetite for AA batteries, giving owners a way to power the handheld from a rechargeable pack instead. DMG-04 and DMG-04A: The Interactive Play Cable The link cable that turned the Game Boy into a social machine appears here as DMG-04, sold in Japan under the wonderful name the Interactive Play Cable. It connects two consoles for head-to-head play and trading. There is also a revised edition, DMG-04A, a shielded version of the same cable, and having both the original and the revision side by side is a lovely detail for a completist. DMG-07 and DMG-08: Four Players and a Clean Machine The line did not stop at two-player duels. DMG-07 is the four-player adapter, which let up to four Game Boys join a single game for the handful of titles that supported it, turning a quiet corner into a miniature tournament. And to keep everything running sweetly, DMG-08 is the official cleaning kit, a small maintenance set for looking after cartridge contacts and the console itself. It is exactly the sort of practical, unglamorous product a carefully planned system includes, and exactly the sort almost nobody bothered to keep. GB-8 and VG-01: Powering the Game Boy Anywhere Two more power options round out the practical side of the line. The GB-8 AC adapter runs the Game Boy straight from a mains socket, ideal for long sessions at home without draining a single battery. The VG-01 car adapter does the same job on the move, drawing power from a car so the handheld could keep going on the longest journeys. Together they show how thoroughly Nintendo thought about keeping the machine alive wherever you were. DMG-05 and DMG-06: The Rare Ones Now for the crown jewels of the set. DMG-05 is the Game Boy battery case, a small box for carrying spare AA batteries, and DMG-06 is the soft case, a simple cloth pouch to protect the console. On paper they are the humblest items in the whole line, a battery holder and a fabric bag. In reality they are the two hardest pieces to find by a wide margin. This is the great irony of accessory collecting. The cheapest, most disposable items are almost always the rarest survivors, precisely because nobody treated them as precious. A battery case and a cloth pouch were exactly the sort of thing that got used up, lost or thrown away without a second thought, while the console and the pricier electronics were kept carefully. As a result, complete and boxed examples of the DMG-05 battery case and the DMG-06 soft case are extremely scarce today, and among serious collectors they can change hands for strikingly high sums, far beyond what their modest original purpose would ever suggest. For collectors, the box is very often the whole game. A loose battery case or a bare cloth pouch is one thing; the same item still in its original carton, with any inserts intact, is another entirely, and the gap in both rarity and value between the two can be enormous. It is the packaging, the thing designed to be torn off and binned, that turns an ordinary accessory into a genuine grail. That is why chasing this line boxed, rather than loose, raises the difficulty so sharply. Why the Complete Japanese Line Matters Owning a Game Boy is easy. Owning every piece of its original Japanese launch family, boxed, in one place, is a different order of challenge entirely. It means tracking down not just the obvious, desirable electronics but the forgettable little extras that almost nobody bothered to keep. Each box you add is a small victory, and the two rarest, the battery case and the soft pouch, can take years to find in good condition. Seen together, this DMG box line is a portrait of how completely Nintendo planned the Game Boy as a system rather than a single gadget. From the console to the headphones, the cables, the power adapters and the humble carrying cases, every need was anticipated and given its own numbered, boxed product. You can explore the full Japanese accessory family, and the rest of the DMG-01 world, across the collection.
