Miyoo Mini Plus 2026: 28,000 Games, PS1 Ceiling

There is a number printed on nearly every preloaded Miyoo Mini Plus listing in 2026, and it is the most honest lie in budget retro hardware: 28,000 games built in. That figure is real in the narrow sense that someone did, in fact, copy roughly twenty-eight thousand ROM files onto a 128GB microSD card and shrink-wrap the result. It is a lie in every sense that matters to a person who intends to actually play something before they die.

This is a review of the game list, not the sticker. It is about the two or three hundred titles you will genuinely return to, the systems this thumb-sized machine runs without complaint, and the exact point on the timeline where the silicon stops cooperating. That point sits, with some irony, inside the gray plastic of the original Sony PlayStation. The Miyoo Mini Plus is a device defined entirely by its library, and the library is defined entirely by a dual-core ARM chip and 128MB of RAM that were never going to render Mario in three convincing dimensions.

So we are reviewing the list. What it holds, what it fakes, and whether the honest version of it, call it the playable list, is worth roughly the price of two-thirds of one new console game. The Machine will spoil the ending for the impatient: it is worth it. Emphatically. Just not for any of the reasons the box art is shouting at you.

The 28,000-Game Lie

Before we praise this thing, and we will praise it, we have to dismantle the marketing, because the marketing is the single most misleading thing about an otherwise honest little device. The 'game list' is not a curated catalogue. It is a data-dump wearing a curated catalogue's clothes.

What the sellers actually ship

Search any marketplace in 2026 for a Miyoo Mini Plus and the bare handheld will be sitting next to a fatter, pricier listing: the same device with a 128GB microSD card pre-loaded and advertised, in bold, as roughly 28,000 games built in. This is not fraud in the criminal sense. Someone genuinely wrote twenty-eight thousand ROM files to that card. The only question worth asking is what those files are.

They are full 'no-intro' romsets for every system the device supports, plus complete arcade dumps, plus regional duplicates, plus ROM hacks, betas, prototypes, translation patches, and homebrew. A single arcade or Neo Geo set can add several thousand entries on its own, most of which are BIOS files, parent-and-clone variants, or games nobody has voluntarily loaded since the first Bush administration. Twenty-eight thousand is what you get when you copy-paste the internet onto flash storage and call the byte count a feature. We have counted the real, deduplicated list ourselves, and the number that survives contact with reality is closer to six thousand than to twenty-eight.

Why the number is true and worthless at once

Here is the cascade every buyer should have in their head. The marketing says 28,000. Strip the duplicate regions, the arcade clone sets, the broken dumps, and the hacks, and the honest aggregate lands near 6,041 distinct, launchable titles. Strip that down to games that (a) run at full speed on this exact hardware and (b) a sane adult would choose to replay, and you are left with a shelf you could count in an afternoon: a few hundred, heavily weighted toward the 8-bit, 16-bit, and PlayStation eras.

None of that is a knock on the hardware. It is a knock on the number. A Game Boy library of two hundred genuinely great cartridges is one of the finest things in this hobby. Dressing it up as 28,000 does the device a disservice, because it invites the one comparison the Mini Plus always loses: the comparison to a machine that promises everything.

The Machine's thesis

So here is the position this review takes and will not abandon. The Miyoo Mini Plus is one of the best values in handheld gaming, and the 28,000-game claim is the worst thing about it. Judge the device by what it runs beautifully, everything from the Game Boy up to a curated shelf of PlayStation classics, and it earns every cent. Judge it by the count on the shrink-wrap, and it is selling you a library you will never load, on a screen the size of a playing card, with no analog stick. We choose to judge it as the former, and we will hold it to that standard without mercy.

What the Hardware Actually Runs

The only 'game list' worth publishing is the one filtered by the phrase 'at full speed.' Everything else is aspiration. A 2026 emulation guide from the community and compatibility trackers such as Playhouse.io converge on a remarkably tidy picture of where this SoC thrives and where it drowns.

The full-speed tier: Game Boy to PlayStation

According to that 2026 breakdown, the Mini Plus runs the following at full speed with no asterisks worth printing: Game Boy, Game Boy Color, Game Boy Advance, NES, SNES, Mega Drive/Genesis, Master System, Neo Geo, arcade, and PlayStation 1. That is the entire spine of two-dimensional console history, from Tetris to Symphony of the Night, in one pocket. The guide's list of titles that simply 'run perfectly' reads like a museum wing: Chrono Trigger, Pokemon, Zelda, Tetris, Kirby, Super Mario World, Street Fighter II, Sonic, Streets of Rage, Gunstar Heroes, and Metal Slug. If your idea of a great evening is any of those, the review is essentially over and the answer is yes.

The PlayStation ceiling

The important half of the story is the top of the stack, because the top of the stack is where the device stops. For the PlayStation, the 2026 guide lists a deep bench of titles that are reliable at full speed: Final Fantasy VII, VIII, and IX; Crash Bandicoot 1 through 3; Spyro 1 through 3; Metal Gear Solid; Castlevania: Symphony of the Night; Tekken 3; Gran Turismo 1 and 2; Resident Evil 1 and 2; Tony Hawk's Pro Skater 1 and 2; Wipeout; and Ridge Racer. That is not a consolation library. That is a killer app list on its own, and it is why we call this the PlayStation ceiling rather than a wall. It is a ceiling you can stand on comfortably; you just cannot climb through it. We gave the PlayStation ceiling its own full autopsy, because it is the single most important fact about the machine.

The Nintendo 64 delusion

Now the bad news, and the reason the '28,000 games' pitch is actively harmful: it makes people believe the fifth generation of 3D consoles is on the menu. It mostly is not. The same 2026 guide flags the demanding Nintendo 64 software by name, and the names are the ones you actually want: Majora's Mask, Banjo-Kazooie, and Donkey Kong 64 are called out as heavy going rather than easy fits. There are lighter N64 titles the guide says can work with tweaks, specifically Super Mario 64, Mario Kart 64, and GoldenEye, but 'works with tweaks' is a different product category from 'runs perfectly,' and you should treat it that way. If N64 is your reason for buying, buy something else. Better still, buy hardware built to do N64 properly and leave the Mini Plus to the two-dimensional canon it actually masters. The device has no analog stick, which alone disqualifies half the N64 catalogue on ergonomic grounds before emulation accuracy even enters the argument.

Specs and the Library Ceiling

The library ceiling is not an accident of software. It is dictated, to the megabyte, by the parts inside the shell. Understand the silicon and you can predict the game list without ever reading a compatibility chart.

The silicon that draws the line

The Miyoo Mini Plus is a study in disciplined cost-cutting. It pairs a modest dual-core application processor with a genuinely lovely little screen and almost nothing else. Here is the full accounting, drawn from Miyoo's own figures and community teardowns.

Note that every number above is hardware, not benchmark theatre. The Mini Plus does not advertise frame rates because it does not need to; the parts tell you the story.

Why 128MB of RAM decides the catalogue

The single most important line in that table is the RAM. 128MB is plenty for systems whose entire address space was measured in kilobytes and low megabytes. It is comfortable for the PlayStation, whose main RAM was two megabytes and whose emulation overhead this chip can absorb. It is a brick wall for the Nintendo 64, the Sega Saturn, the Nintendo DS, and the PSP, all of which demand either more memory, more parallel compute, or emulation techniques this dual-core A7 cannot sustain. When a marketplace listing implies otherwise, the RAM is the fact that quietly calls it a liar. It is also why we spent a whole separate piece pitting this device's 128MB against the Anbernic RG35XX's full gigabyte; the memory gap is the entire plot.

OnionOS and the 100-plus emulators

A 2026 review argues, correctly, that the Mini Plus is still relevant in large part because of OnionOS, describing the community-built firmware as something that materially improves the stock experience rather than merely reskinning it. OnionUI's own GitHub description does not undersell it either: it calls the project an OS overhaul for Miyoo Mini and Mini+ and advertises 100+ built-in emulators plus auto-save/resume and deep customization. The current builds sit on the 4.x release-candidate line, which matters because plenty of retailers still ship cards imaged with stale 1.x or 2.x versions. The takeaway is blunt: the stock firmware is the device at 60 percent, and OnionOS is the device at 100. Budget an hour to install it and never look back.

The Games That Define the List

Every platform has a handful of titles that justify its existence. On the Mini Plus, those titles are disproportionately the reason to own it. Here is the shortlist that actually defines the game list, organized by the eras this chip was born to run.

8-bit and 16-bit: the comfort food

This is the device's home turf and its greatest strength. Chrono Trigger, assembled by the so-called Dream Team of Hironobu Sakaguchi, Yuji Horii, and Dragon Ball's Akira Toriyama, remains the benchmark against which portable JRPGs are measured, and it runs flawlessly here. Super Mario World, Street Fighter II, Sonic, Kirby, Zelda, Streets of Rage, and Treasure's astonishing Gunstar Heroes all fall into the '2026 guide says runs perfectly' bucket. The 16-bit library is where the Mini Plus feels less like an emulator and more like a time machine with a warranty. For the deeper historical context on any of these, the archives at Hardcore Gaming 101 remain the standard reference, and they take these games as seriously as the games deserve.

The PlayStation crown jewels

The PS1 shelf is what elevates this from a nostalgia toy to a genuinely serious portable. Symphony of the Night is routinely credited, alongside Super Metroid, with defining the entire 'Metroidvania' template; playing it on a crisp 640x480 panel is arguably a better experience than the CRT-blurred original. Metal Gear Solid, Tekken 3, and Gran Turismo were the games that proved a home console could deliver arcade-grade spectacle, and this handheld runs the lot at full speed. The one caveat is the missing analog stick: Gran Turismo and the 3D fighters are playable on the D-pad, but the twin-stick 3D shooters of the late PS1 era will always feel like a compromise. Historians of the medium, including Jimmy Maher's meticulous Digital Antiquarian, have written at length about how the CD-ROM and the 32-bit leap reshaped the industry; the Mini Plus lets you replay that inflection point in your palm.

Arcade and Neo Geo: Metal Slug and friends

The arcade and Neo Geo support is the underrated third pillar. SNK's Metal Slug series, with its absurd hand-drawn sprite animation, is exactly the kind of pick-up-and-play spectacle a pocket device should showcase, and the 2026 guide confirms it runs perfectly. The catch, as always, is the marketing: 'arcade support' is where most of those fictional 28,000 games hide as clone sets and BIOS files. The real arcade list you care about is a few hundred cabinets, not tens of thousands. Below is how a handful of the true defining titles stack up.

How It Plays: Five Scenarios

Specs and lists are theory. The only test that matters is how the thing feels in five different pairs of hands. The Machine has held it in all five.

The casual and the completionist

For the casual player, the one who wants twenty minutes of Pokemon on the sofa, the Mini Plus is close to ideal. OnionOS boots fast, its auto-resume drops you back exactly where you left off, and the 640x480 panel makes Game Boy Color and GBA titles look better than they ever did on original hardware. This is the scenario the device was designed for, and it is the one a 2026 product review explicitly endorses: a handheld for quick pick-up sessions, not for heavier systems.

For the completionist, the grinder chasing every Chrono Trigger ending or every SNES JRPG to 100 percent, the story is nearly as good, with one caveat. The device excels at long-form 2D RPGs, thanks to save states and reliable full-speed emulation, but the small battery means a marathon session will want a USB-C cable within reach. As a 200-hour JRPG machine it is superb; as an untethered all-dayer for PS1-heavy backlogs it is merely good.

The speedrunner and the co-op night

The speedrunner gets a mixed verdict, and honesty demands stating it plainly. Save states and rewind are gifts for practicing routes, and input latency on OnionOS is respectable for a device this cheap. But the D-pad, while decent, is not a competition pad, and the absence of an analog stick removes any run that depends on analog control. It is a fine practice tool and a poor place to set a world record.

The co-op night is where the Mini Plus simply says no. There is one screen roughly the size of a business card, no second controller port that matters, and no realistic local multiplayer story. Pass-the-handheld works for turn-based games and nothing else. If your fantasy is Streets of Rage 2 with a friend on the couch, this is the wrong device by a wide margin. This is the single scenario where the hardware's cost-cutting is genuinely felt as a loss.

The commuter

The mobile / commuter scenario is the one the Mini Plus wins outright and the reason it exists. It disappears into a coat pocket, wakes instantly from sleep, and holds a full 2D console library that will outlast any train delay. The Wi-Fi added on the Plus revision lets you scrape box art and, if you care, wire up RetroAchievements without ever touching a PC. For the person who wants a Game Boy that also happens to contain the SNES, the Genesis, and a shelf of PlayStation RPGs, on a commute, there is very little to argue with and a great deal to love.

Miyoo Mini Plus vs the Field

No device exists in a vacuum, and the budget handheld shelf in 2026 is crowded. The Mini Plus's game list only makes sense next to the lists of its rivals, because the differences are almost entirely about where each machine's ceiling sits.

Versus the Anbernic RG35XX

The natural rival is the Anbernic RG35XX, which in its current H700 generation packs a quad-core Cortex-A53 and a full gigabyte of RAM against the Mini Plus's dual-core A7 and 128MB. On paper that is a rout, and in practice it does buy the Anbernic a slightly higher, more selective ceiling: some Dreamcast, some PSP, some Nintendo DS, where the Miyoo simply cannot follow. The RG35XX also adds HDMI-out and Bluetooth, neither of which the Miyoo offers. What the extra silicon does not buy is a better experience within the shared 2D-to-PS1 library, where OnionOS and the Miyoo's superb screen keep it fully competitive at a lower price.

Versus the original Mini and the step-up crowd

Against its own predecessor, the original Miyoo Mini, the Plus wins on the two things that matter for a modern buyer: a larger 3.5-inch screen and the addition of Wi-Fi. The core game list is identical because the SoC and RAM are effectively the same, so anyone still running an original Mini has no library reason to upgrade, only a comfort reason. The step-up crowd, meanwhile, is a different market entirely: an Android-based Retroid Pocket breaks the PS1 ceiling and reaches GameCube and PS2, but it costs roughly four times as much and trades the Miyoo's pocketable simplicity for a small computer that needs managing.

The library-per-dollar verdict

Measured on the only metric that counts for this review, great games per dollar within the systems it actually runs, the Mini Plus is arguably the leader of the entire category. It does not have the highest ceiling. It has the best floor-to-price ratio, and for a library that tops out at the PlayStation, a higher ceiling is a feature you are paying for and not using.

Setup: Firmware, FAT32, OnionOS

The gap between the Mini Plus as sold and the Mini Plus as it should be is one firmware install wide. This is the least glamorous and most important part of the review, because it is the difference between the 60-percent device and the 100-percent one.

The firmware floor: 20230505

A 2026 setup guide is specific on one prerequisite that trips people up: the Miyoo Mini Plus needs its stock firmware at a version of at least 20230505 before OnionOS will install successfully. Units that have been sitting in a warehouse may ship on older firmware, so the very first step is checking the version and, if necessary, updating the stock OS before you go anywhere near the community firmware. Skip this and the install fails in ways that look like a bricked device but usually are not.

Format FAT32, not exFAT

The second non-negotiable is the filesystem. The same guide recommends formatting a new microSD card as FAT32 rather than exFAT before installing OnionOS. This matters because most large cards ship pre-formatted as exFAT out of the box, and OnionOS expects FAT32. It is a thirty-second fix that prevents an evening of confusion. That this workflow is still being documented in 2026 tells you the platform is alive and well: one prominent YouTube install guide for OnionOS on the Mini Plus was published on 2026-03-27 and was still being updated as of 2026-08-13, and an earlier walkthrough from 2025-07-19 shows the current method has been stable since mid-2025.

The folder structure that makes the list work

Once OnionOS is on the card, the game list lives inside a folder structure that is worth understanding, because it is where your ROMs and BIOS files must go for each system to appear. If you would rather assemble the emulation stack yourself rather than trust a seller's card, our guide to installing cores by hand covers the same ground for the wider RetroArch ecosystem. A representative OnionOS layout looks like this:

/                      (microSD root, FAT32, MBR)
|-- .tmp_update/       <- OnionOS boot payload (do not delete)
|-- BIOS/              <- neogeo.zip, PS1 BIOS, gba_bios.bin, etc.
|-- Roms/
|   |-- GB/            <- Game Boy
|   |-- GBC/           <- Game Boy Color
|   |-- GBA/           <- Game Boy Advance (needs gba_bios.bin)
|   |-- FC/            <- NES / Famicom
|   |-- SFC/           <- SNES / Super Famicom
|   |-- MD/            <- Mega Drive / Genesis
|   |-- MS/            <- Master System
|   |-- NEOGEO/        <- Neo Geo (needs neogeo.zip in BIOS)
|   |-- ARCADE/        <- FBNeo / MAME sets
|   \-- PS/            <- PlayStation 1 (.chd or .pbp)
\-- Saves/             <- auto-save data and save states

Folder names can vary slightly between OnionOS releases, but the principle holds: one folder per system, BIOS files in their own directory, and saves handled automatically. Get this right once and the '28,000 games' problem becomes a 'which 300 games do I actually want' problem, which is a much nicer problem to have.

Pricing and Availability

The Mini Plus is cheap, but 'cheap' hides a few different configurations, and one of them is the marketing trap dressed up as a bargain. Here is how the money actually breaks down in 2026.

Bare unit versus the 28,000-game bundle

The bare device, no card, streets at around $53.99. That is the honest price of the hardware. The preloaded bundles cost meaningfully more and their premium buys you a microSD card padded with a romset you did not curate and legally do not own. The Machine's recommendation is unambiguous: buy the bare unit, add your own card, and keep the difference.

The legal asterisk on a preloaded card

There is a reason we keep saying 'gray area.' The device itself is entirely legal; emulation is legal; owning a Miyoo Mini Plus is no more suspect than owning a DVD player. A microSD card someone else filled with twenty-eight thousand copyrighted ROMs is a different object, and the person profiting from copying those files is the one taking the risk, whether they advertise it or not. Buying the bare unit and dumping your own cartridges is the clean path, and it also happens to produce a tidier, better-organized library than any seller's data dump.

Where to buy in 2026

Availability is not a problem. The Mini Plus is sold through the usual marketplace channels and specialist retro-handheld shops, in a rotating cast of colors, and stock has been steady throughout 2026. The active community, the constantly-updated install guides, and OnionOS's ongoing development all point to a device that is far from end-of-life despite being a 2023 product. In a category where hardware is obsoleted every few months, that longevity is itself a feature.

Who Should Buy It

A review that recommends a product to everyone has recommended it to no one. The Mini Plus is a precise instrument for a specific job, and the honest use-case list is short on both sides.

Buy it if

Buy it if you want a genuinely pocketable machine that runs the entire 2D console canon and a deep bench of PlayStation classics at full speed. Buy it if your gaming happens in twenty-minute windows, on commutes, in waiting rooms, on the sofa. Buy it if you are a lapsed player chasing GBA and SNES nostalgia and you want the cheapest excellent way to scratch that itch. Buy it if you are curious about emulation and want a low-risk, roughly-$54 entry point that a strong community will help you set up.

Skip it if

Skip it if your wishlist is N64, Dreamcast, PSP, DS, GameCube, or PS2; the RAM ceiling means those are either broken, marginal, or absent, and no firmware fixes physics. Skip it if you need an analog stick for the 3D games you love. Skip it if local co-op is central to your fun, because the single tiny screen makes that a non-starter. Skip it, above all, if the '28,000 games' number is what sold you, because that number is the one promise this device cannot keep.

The five people this device was built for

1. The commuter who wants a Game Boy that secretly contains the SNES, the Genesis, and a shelf of PS1 RPGs.
2. The JRPG completionist chasing Chrono Trigger and Final Fantasy VII to 100 percent with save states as a safety net.
3. The budget-conscious PS1 fan who wants Symphony of the Night and Metal Gear Solid in a pocket for the price of a paperback boxset.
4. The emulation newcomer who wants a cheap, well-documented, community-supported way to learn the ropes without risking real money.
5. The collector who wants a pocketable second screen for the 2D catalogue and already owns bigger hardware for everything above the PlayStation.

The Verdict

Strip away the marketing and the Miyoo Mini Plus is exactly what it has always been: a superb, disciplined, deliberately limited machine that plays the best two-dimensional games ever made, plus a killer PlayStation bench, for less than the cost of one new console release. The only things standing between it and a higher score are self-inflicted: a missing analog stick and a game-list claim built to deceive.

Pros

• Runs the full 8-bit-to-PS1 canon at full speed, per the 2026 compatibility guides.
• OnionOS transforms it: 100+ emulators, auto-save/resume, instant sleep and wake.
• Genuinely pocketable, with a sharp 3.5-inch 640x480 IPS panel that flatters old games.
• Wi-Fi on the Plus revision enables box art and RetroAchievements without a PC.
• Costs around $53.99 bare, less than two-thirds of one new console game.
• Enormous, still-active community and documentation, with install guides updated through August 2026.

Cons

• No analog stick, which hobbles PS1 3D titles and rules out analog-dependent games.
• A hard ceiling at the PlayStation; N64 is marginal, and Dreamcast, PSP, DS, and PS2 are out.
• The '28,000 games' marketing is padded filler and a legal gray area.
• Small screen and a modest battery that PS1 emulation drains quickly.
• Local co-op is effectively impossible on a single card-sized screen.
• Stock firmware is merely adequate; you must install OnionOS to get the real device.

The rating: 8 out of 10

As an 8-bit-to-PlayStation pocket machine running OnionOS, the Miyoo Mini Plus is close to a perfect budget object, and it earns a confident 8/10. The two points it loses are the missing analog stick and the dishonest library math, not the emulation, the screen, or the value, all of which are excellent. Buy the bare unit for about $54, format a card to FAT32, flash OnionOS onto firmware 20230505 or newer, and curate the few hundred games you will actually replay. Ignore the twenty-eight thousand. The real game list is smaller, sharper, and far more satisfying than the number on the box, and it fits in your pocket.
