There’s a particular kind of melancholy that settles over you when you hold a WonderSwan Color for the first time. It’s the weight of it, mostly β that strange, asymmetrical heft that feels less like a games console and more like a piece of industrial design from a parallel timeline where Nintendo lost. Which, in a way, is exactly what it is. This was Gunpei Yokoi’s final handheld, finished by his successors at Koto Laboratory after his death in 1997, and brought to market by Bandai in 1999 to challenge the Game Boy Color on its home turf. It sold about 3.5 million units in Japan. It never officially left the country. And then, by 2003, it was effectively dead, killed by the same Game Boy Advance that everyone assumed it would at least scratch.
I’ve spent the better part of eight months β between other assignments, between the inevitable distractions of a Steam Deck and a backlog the size of a small library β playing through the WonderSwan’s exclusive catalogue. Not the FromSoftware ports. Not the Final Fantasy remakes that eventually made their way to other platforms. The genuine, never-localised, never-ported, never-anything-else-but-here exclusives. There are, depending on how generous you’re being with the definition of “exclusive,” somewhere between 60 and 90 of them across the original WonderSwan, the WonderSwan Color, and the SwanCrystal.
Most of them, I’m sorry to report, are not very good. A great many of them are cheap licensed tat aimed at the Japanese commuter market β Gundam card battlers, Digimon spin-offs, dating sims for franchises I’ve never heard of. But buried in that mass of mediocrity are a handful of games that genuinely justify the cost of importing the hardware, learning enough kana to navigate menus, and explaining to your partner why there’s now a third grey rectangle on the shelf next to the Neo Geo Pocket Color and the Game Gear. These are the seven worth your time.
A Brief History of Bandai’s Beautiful Failure
To understand what makes the WonderSwan worth caring about in 2024, you need to understand what it was trying to do in 1999. Gunpei Yokoi had left Nintendo in 1996 after the Virtual Boy debacle, founded Koto Laboratory, and signed a development deal with Bandai. The original WonderSwan, launched on 4 March 1999 at Β₯4,800 (around Β£28 at the time, an astonishingly low price), was the result. It was monochrome, ran on a single AA battery for approximately 40 hours, and weighed just 93 grams. Compared to the contemporary Game Boy Color β Β₯8,900, two AA batteries, 30 hours β it was a genuine threat.
The hardware itself was idiosyncratic in ways that betrayed Yokoi’s fingerprints. The console could be held either horizontally, like a Game Boy, or vertically, like a pager β and many games used the vertical orientation for shoot-’em-ups and RPGs. The two D-pads (one on each side when held horizontally) felt strange at first but became the platform’s defining ergonomic feature, allowing for vertical-orientation games where one D-pad handled movement and the other handled menu navigation. The sound chip was capable but tinny through the mono speaker (headphones required a separate adaptor, in true Yokoi cost-cutting fashion).
The WonderSwan Color followed on 9 December 2000, adding a 4096-colour palette (241 displayable simultaneously) and doubling the RAM to 64KB. The SwanCrystal arrived in July 2002 with a vastly improved TFT display that finally eliminated the ghosting that had plagued earlier models. By then, the GBA had been out for over a year and the writing was already on the wall.
Why You Should Care Now
Two things make 2024 a particularly good time to investigate the WonderSwan. First, hardware prices have stabilised β a working SwanCrystal in good condition can be had on Yahoo Japan Auctions or Suruga-ya for around Β£60-90, with most games costing between Β£5 and Β£20. Second, the modding community has produced genuinely excellent solutions for the platform’s biggest weaknesses: IPS screen mods now exist for both the WSC and SwanCrystal, and flashcarts like the WonderWitch and various Chinese-manufactured everdrive equivalents make playing the entire library trivial.
Emulation, too, has finally caught up. Mednafen’s WonderSwan core is essentially flawless, and the standalone Ares emulator handles even the trickier vertical-orientation games elegantly. If you’re playing on an Analogue Pocket, the openFPGA WonderSwan core released by agg23 in 2023 is, frankly, the best way to experience these games short of original hardware with an IPS mod. The barrier to entry has never been lower.
The Methodology: How I Picked These Seven
Before we get to the games, a word on selection criteria. I set myself three rules. First, the game had to be a WonderSwan exclusive in the strictest sense β no Final Fantasy I & II remakes (which later appeared on GBA and PSP), no Rockman & Forte: Mirai Kara no ChΕsensha (which is technically a sequel but borrows extensively from the SNES original), no FromSoftware Souls-adjacent dungeon crawlers that received PS1 ports. The game had to live and die on the WonderSwan. Second, it had to be playable by someone with limited Japanese β either through fan translation patches that exist and work, or through gameplay that transcends language barriers. Third, it had to be genuinely good in 2024, not merely “interesting” or “historically important.”
The seven games that follow met all three criteria. They span genres from tactical RPG to puzzle-platformer to immersive sim (yes, really, on the WonderSwan), and represent what I genuinely believe to be the artistic high points of a platform that deserved more than the obscurity history granted it.
1. Judgement Silversword: Rebirth Edition (2004)
Let’s start with the masterpiece. Judgement Silversword has the kind of origin story that gets retold so often in shmup circles that it’s become a kind of folk legend. It began life as the winning entry in Qute Corporation’s WonderWitch programming competition in 2001 β developed by a single programmer, Yusuke Hashimoto, on the official WonderSwan homebrew development kit. Qute liked it so much they retained Hashimoto and released a commercial cartridge version in 2004, just before the platform’s commercial death.
What landed on that cartridge is, no exaggeration, one of the finest portable shoot-’em-ups ever made. It’s a vertical-orientation arcade shooter β you turn the WonderSwan on its side and use the bottom D-pad for movement, the top buttons for fire and bomb. The game runs at a silky 60fps with a bullet density that frankly shouldn’t be possible on hardware this modest, and across its 22 stages it manages to teach you, beat by beat, how to read patterns in a way that feels less like a series of escalating arcade challenges and more like a chamber-music composition.
Why It Still Works
The genius of Judgement Silversword is its scoring system. You have a “tension” meter that builds as you graze bullets and destroy enemies, and which decays if you play conservatively. High tension multiplies your score but also makes enemies more aggressive. It’s a feedback loop that punishes the timid and rewards the brave, and it transforms what would otherwise be a competent but unremarkable shooter into one of the most replayable arcade experiences on any handheld. The “Rebirth Edition” specifically β there are bootleg copies of earlier versions floating around β includes the bonus Cardinal Sins boss-rush mode, which is essentially a separate game in its own right.
Expect to pay Β£80-120 for an authentic boxed copy. There is no fan translation because there’s almost nothing to translate. Buy it, play it, weep at how good handheld shmups can be.
2. Riviera: The Promised Land (2002, original WSC version)
Most retro gaming enthusiasts know Riviera as a GBA game, or perhaps the PSP remake. What they don’t know β what I didn’t know until I went looking β is that the original 2002 WonderSwan Color version is meaningfully different and, in some respects, better than its more widely distributed successors.
Developed by Sting and published by Bandai, Riviera is a tactical RPG-slash-visual novel about a winged warrior named Ein sent to investigate the mysterious island of Riviera. The combat system is genuinely unique even now: you carry only a limited number of items into each battle, items have limited uses, and the items themselves level up rather than your character. It’s a system that forces you to constantly evaluate what you’re willing to “spend” on any given encounter, and it works beautifully.
The Case for the Original
The WSC version has a slightly different script, character art that some longtime fans (myself included) prefer to the GBA redraw, and an exploration system that’s more streamlined than the often-criticised GBA implementation. Crucially, a complete English fan translation patch by Crimson Nocturnal was released in 2018 and works flawlessly on hardware via flashcart.
If you’ve played the GBA or PSP version and bounced off it, the WSC original is worth a second look. If you’ve never played any version of Riviera, this is genuinely one of the most original RPGs of its era, and the WonderSwan version is the truest expression of Sting’s vision before the platform-jumping diluted it. Loose carts go for around Β£15-25.
3. Gunpey (1999)
It would have been wrong to write this piece without mentioning Gunpey, the puzzle game named in tribute to Gunpei Yokoi himself, released as a launch title in March 1999 and arguably the best argument for the WonderSwan’s vertical-orientation design philosophy.
The concept is deceptively simple. You have a grid of cells, each containing a line segment that runs in one of four diagonal orientations. Rows shift upward as new lines appear from the bottom, and your job is to swap cells vertically to connect lines into an unbroken chain that spans the entire width of the playfield. Clear a line and the connected segments vanish. Let the grid fill and you lose.
Why It’s More Than a Curiosity
What makes Gunpey special β beyond its obvious historical significance as a launch title for a console designed by the recently-deceased man it honours β is how perfectly it suits the hardware. The vertical orientation and dual D-pad layout were practically designed for this game, and the score-attack mode generates the same kind of compulsive “one more go” energy as Tetris or Lumines. There’s a Puzzle mode that teaches the mechanics across 100 increasingly devious set-piece challenges, and an Endurance mode that will eat your battery and your soul in equal measure.
Later versions appeared on PSP and DS, but neither captures what the WonderSwan original gets right: the tactile click of those tiny D-pads, the way the vertical screen forces you to physically reconfigure your relationship with the console. It’s a game that could only have existed here. Cartridges are extremely cheap β around Β£5-10 β and you don’t need a word of Japanese to play.
4. Final Lap 2000 (1999) β and Why I Almost Didn’t Include It
I went back and forth on this one. Final Lap 2000 is, by any technical measure, an absurd achievement: a top-down racing game with a working multiplayer mode via the WonderSwan’s communication cable, developed by Namco and based on the arcade Final Lap series. On the surface it’s the kind of competent-but-unremarkable racing game that a launch window typically produces.
But spend a few hours with it and something strange happens. The handling model β which initially feels twitchy and over-sensitive β reveals itself as one of the most demanding portable driving experiences of its generation, requiring you to read corner geometry several beats ahead and feather the throttle with millimetric precision. There are no rubber-band physics, no concessions to handheld accessibility. It’s an arcade racer that respects you, on hardware that arguably shouldn’t have been able to deliver one.
I’m including it because it represents something the WonderSwan library does often and which no other handheld of its era did consistently: it ports an arcade experience without compromise, trusting the player to meet the hardware where it lives. Cartridges run Β£8-15.
5. Dicing Knight Period (2003)
If Judgement Silversword is the WonderSwan’s shmup masterpiece, Dicing Knight Period is its roguelike one. Developed by Qute (yes, the same Qute) and released as one of the last commercial cartridges in late 2003, this is a Mystery Dungeon-style top-down dungeon crawler with a single, brilliant twist: every action you take consumes a face on your dice-shaped life meter.
You start each floor with six “lives” represented as faces on a die. Each step, each attack, each spell consumes a face. Run out and you lose a die entirely. Run out of dice and you die, lose all your items, and start the dungeon again. It’s a permadeath system that turns every floor into a tense exercise in resource management β do you push deeper to find better loot, or retreat to preserve your remaining dice?
The Long Tail
The dungeons are procedurally generated, the loot system is rich without being overwhelming, and the whole thing fits onto a single WonderSwan Color cartridge with style to spare. There’s a fan translation by NopeNotNow released in 2019 that handles the menus and item descriptions; the small amount of plot is incidental.
The catch, and it’s a significant one, is price. Dicing Knight Period was a late-life release with a tiny print run, and authentic copies regularly sell for Β£200+ on Yahoo Auctions. This is one of those games where flashcart access is genuinely justified β there’s no realistic prospect of playing the original at sensible prices, and the game is too good to skip on principle.
6. Glocal Hexcite (1999/2000)
Bear with me. Glocal Hexcite is an abstract strategy game on a hexagonal board, somewhere between Go and the Settlers of Catan, originally developed as an arcade game in Japan and ported to the WonderSwan in 2000. You place triangular pieces on a hex grid, claiming territory by completing larger shapes, and the AI is brutal in ways that genuinely surprised me.
This is the kind of game that the WonderSwan was uniquely positioned to host β a thinky, low-input, high-stakes board game that benefits from being playable in five-minute commutes β and which never found a home elsewhere because no other platform’s audience would have tolerated something this stubbornly cerebral. It’s not flashy. It’s not story-driven. It’s just a tremendously well-designed abstract strategy game that you can sink hundreds of hours into without ever feeling like you’ve fully solved it.
There’s no translation needed and no translation exists. Carts are dirt cheap β Β£5-10 β and if you have any affection for the abstract strategy genre, this is one of the most overlooked entries of its era on any platform.
7. Mr. Driller (2000)
The WonderSwan version of Namco’s Mr. Driller deserves inclusion not because it’s the best version β that honour probably goes to the arcade original or the Dreamcast port β but because it’s the version that best fits the platform’s strengths. The vertical-orientation option turns the entire screen into a single tall drilling shaft, far taller than the horizontal arcade configuration allowed, and the result feels less like a port and more like a remix of the original concept.
For the uninitiated: you control a drill operator descending through coloured blocks, matching three or more of the same colour to clear them while managing a depleting air supply that refills only when you collect specific items. It’s pure arcade chase-the-score design, and the WonderSwan’s two-D-pad layout maps to the controls perfectly β one D-pad for movement, the other for menu navigation between runs.
Loose cartridges are Β£10-20, no translation needed, and you’ll lose more hours to it than you’d like to admit. It’s the perfect bus-stop game on the perfect bus-stop console.
Build Quality and the Hardware Itself
Let’s talk about the actual machine you’ll be playing these on, because the WonderSwan’s build quality is one of the more interesting stories in handheld history. The original 1999 model and the WSC use the same chassis β a slightly bulbous, asymmetric plastic shell that feels, in 2024, like a curiosity from an alien design tradition. The plastic is dense and good-quality, the buttons have a satisfying mechanical click, and the dual D-pads β which I confess to finding awkward for the first hour or so β quickly become second nature.
The SwanCrystal, released in 2002, addressed the platform’s worst weakness: the dire passive-matrix LCD that made fast-moving games on earlier models look like they were happening underwater. The Crystal’s TFT display is genuinely sharp, with respectable response times and significantly improved colour reproduction. If you’re buying hardware in 2024, the SwanCrystal is the only model worth considering for serious play.
The IPS Mod Question
That said, even the SwanCrystal’s display is showing its age, and the modding community has responded. Several Chinese sellers β RetroSix and FunnyPlaying among the more reputable β sell IPS replacement screens for both the WSC and SwanCrystal, with installation kits running Β£40-60. The transformation is dramatic: brightness, contrast, and viewing angles all improve to the point where the modified Crystal is genuinely competitive with a modded Game Boy Advance for image quality.
I’d strongly recommend the mod if you plan to play these games seriously. The installation is moderately fiddly β you’ll need to be comfortable with soldering and ribbon cables β but the results are transformative.
Display, Performance, and the Sound of a Forgotten Era
The WonderSwan’s screen is 224Γ144 pixels β slightly higher resolution than the Game Boy Color’s 160Γ144 β and runs at 75Hz, which gives the platform a slightly smoother feel than its competitors when running well-optimised games. Judgement Silversword‘s 60fps bullet patterns are a direct beneficiary of this headroom.
The CPU is an NEC V30MZ running at 3.072MHz β significantly faster than the Game Boy Color’s Z80 derivative β and the result is a platform that handled 2D sprite work with genuine confidence. Where the GBC struggled with anything more than a handful of large sprites, the WonderSwan could push dozens without breaking sweat. This is why so many of the platform’s best games are shmups, racers, and action titles: the hardware actually had the bandwidth to deliver them.
Audio is the one area where the WonderSwan falls genuinely short. The four-channel sound chip is competent enough, but the mono speaker is tinny and the lack of an integrated headphone jack β you need a separate adaptor, the WonderWave or similar β is the kind of cost-saving decision that feels uniquely Yokoi. Bring headphones. Or don’t. Half the charm of these games is hearing them through that little speaker on a quiet train.
Battery Life and Daily Use
Here is where the WonderSwan absolutely demolishes its competition, even 25 years on. A single AA battery in a SwanCrystal will give you approximately 20 hours of play; in the original mono WonderSwan, closer to 40. By comparison, two AAs in a Game Boy Color manage about 30 hours total, and a GBA SP needs charging every 10-15 hours.
What this means in practice is that the WonderSwan is, even now, the most travel-friendly handheld of its generation. A handful of Duracells in a coat pocket will see you through a transatlantic flight with hours to spare. There’s something genuinely liberating about a handheld that doesn’t require you to think about charging β you just play it until the battery dies, drop in a fresh AA, and continue.
Software Library: The Wider Context
The seven games above are the highlights, but they exist within a library that’s broader than its reputation suggests. The WonderSwan was home to remarkable ports of Final Fantasy I, II, and IV (the IV port is genuinely excellent), the only handheld version of Star Hearts, several strong FromSoftware dungeon crawlers in the Frontier Tales series, and a surprising number of Bandai’s licensed properties β Gundam, Digimon, Evangelion β that, while not exclusive in concept, often had unique gameplay implementations on this platform.
The platform’s tragedy is that it arrived too late and was killed too quickly. By the time the WonderSwan Color was getting its best software in 2001-2002, the GBA had already swallowed the global handheld market. Many of the WonderSwan’s most interesting late-life releases β Dicing Knight Period, Judgement Silversword β had print runs in the low thousands, which is why prices have climbed so steeply for collectors.
The Collector’s Market in 2024
Speaking of collectors: the WonderSwan market has gentrified significantly in the last five years. A complete-in-box SwanCrystal that might have cost Β£40 in 2018 is now routinely Β£100+. Sought-after games like Dicing Knight and the original Judgement Silversword Cardinal Sins compilation have multiplied in price several times over. This isn’t unique to the platform β the entire retro market has inflated β but the WonderSwan’s small library and limited print runs have made the climb particularly steep.
If you’re buying now, my advice is to prioritise the hardware (a modded SwanCrystal) and a flashcart over a comprehensive collection of original cartridges. The platform’s appeal lies in the games themselves, not in shelf displays, and the cartridges that are genuinely affordable will give you plenty to play with.
Comparisons: WonderSwan vs the Field
The obvious comparison is the Neo Geo Pocket Color, SNK’s contemporary handheld effort and the WonderSwan’s spiritual cousin in commercial doomedness. The NGPC has a more famous library β SNK vs Capcom: Card Fighters’ Clash, the various fighters, Cotton β and arguably better hardware in some respects. But the WonderSwan has more games, a broader range of genres, and a higher ceiling of artistic ambition. Judgement Silversword and Dicing Knight Period have no real equivalents in the NGPC library.
Against the Game Boy Color, the WonderSwan wins on technical capability and loses on library depth. The GBC’s killer apps β PokΓ©mon, Zelda: Oracle, Wario Land 3 β are arguably stronger than anything in the WonderSwan’s exclusive catalogue. But the WonderSwan, for the patient importer, offers a more idiosyncratic, more surprising library. It’s the difference between a greatest-hits compilation and a record-collector’s deep cut: less reliable, more rewarding when it hits.
Against the GBA, there’s no contest. The GBA is the better platform by every objective measure. But that’s the wrong question. The WonderSwan offers experiences you cannot have on the GBA, and that’s the whole point.
Practical Recommendations for the Curious
If this piece has convinced you to investigate, here’s my recommended path. First, source a SwanCrystal in good cosmetic condition from Suruga-ya, Buyee, or a trusted UK reseller (Retro Frog and Console Passion both occasionally stock them). Budget Β£80-100. Second, install an IPS screen β RetroSix’s kit is the most user-friendly, around Β£55. Third, buy a flashcart. The current consensus pick is the WonderSwan EverDrive from Krikzz or the cheaper Chinese alternatives that pop up on AliExpress; expect to pay Β£80-120 for the EverDrive, Β£30-50 for the alternatives.
For first games, start with Gunpey (cheap, language-independent, perfect for the platform), Judgement Silversword (the masterpiece), and Mr. Driller (instant gratification). Once those have hooked you, move to Riviera with the translation patch and Dicing Knight Period. Glocal Hexcite and Final Lap 2000 are the deep cuts you’ll find your way to eventually.
Avoiding the Pitfalls
A few warnings. The WonderSwan’s capacitors are now 25 years old and starting to fail in some units β listen for distorted audio or display issues when buying. The battery contacts can corrode if previous owners left batteries in storage; always inspect the compartment before purchase. And the screen on unmodded units, particularly the original WSC, is genuinely difficult to read in modern lighting conditions; manage your expectations or commit to the IPS mod.
The Verdict: Is It Worth It?
This is where, in a normal review, I’d hand down a score for a piece of hardware. But the WonderSwan in 2024 isn’t really a piece of hardware to be scored β it’s a window into a particular moment in handheld history, the last gasp of Gunpei Yokoi’s design philosophy before the world moved on to backlights and rechargeable batteries and 3D graphics. Whether it’s “worth it” depends entirely on what you’re looking for.
If you want the best portable retro experience for your money in 2024, buy a modded Game Boy Advance SP or, frankly, just an Analogue Pocket. If you want the most efficient way to play the seven games I’ve recommended above, emulate them on a Retroid Pocket or a Steam Deck. The WonderSwan as a piece of hardware cannot compete with modern alternatives on convenience, library depth, or value.
But if what you want is the texture of a road not taken β the feel of holding a console that was almost a legitimate competitor to Nintendo, that housed some of the most idiosyncratic and ambitious portable games of its era, that represented the final design statement of one of the most important figures in handheld history β then yes, absolutely, the WonderSwan is worth it. It’s a platform that rewards effort with experiences you genuinely cannot have anywhere else, and the seven games above are the proof.
Score: 8/10 β A flawed, fascinating handheld with a small but exceptional exclusive library that genuinely justifies the cost of import. Not for everyone. Essential for the curious.
Looking Forward: The WonderSwan’s Legacy
What’s striking, looking at the WonderSwan now, is how much of its DNA persists in modern handheld design. The vertical-orientation play that Gunpey pioneered is everywhere in mobile gaming. The dual-input layouts that the platform normalised informed the Nintendo DS and, eventually, the Switch. The willingness to embrace cerebral, slow-burn experiences on a portable platform β Glocal Hexcite, Dicing Knight Period β feels prescient now in an era of Slay-the-Spire-likes and Vampire Survivors clones.
The platform failed commercially. Bandai discontinued the SwanCrystal in 2003, and the WonderWitch development kit faded shortly after. But the games persist, and the community around them β the translators, the modders, the homebrew developers still releasing new cartridges in 2024 β keeps the platform alive in ways that matter. There are new WonderSwan releases happening this year. Real, physical cartridges, developed by enthusiasts, sold to other enthusiasts. That’s not the legacy of a failed handheld. That’s the legacy of one that mattered.
Gunpei Yokoi never lived to see the WonderSwan launch. He never knew that his final design philosophy β “lateral thinking with withered technology,” using mature, cheap components in clever new configurations β would produce one of the most idiosyncratic handheld libraries of its era. He never knew about Judgement Silversword, designed by a single homebrew programmer on a development kit that wouldn’t have existed without his platform. He never knew that twenty-five years later, a slightly exhausted games journalist would spend eight months playing every exclusive on his last console, and would find seven that genuinely justified the effort.
I think he’d have been pleased. I think he’d have understood. And I think, if you’ve read this far, you might be the kind of reader who’d understand too. Import the hardware. Mod the screen. Play the games. The WonderSwan deserves it, and so do you.
