Budget shortlist candidate
Cartboy is more compelling when you judge it by role, not hype: what it can emulate comfortably, how it should feel in the hand, what it costs, and which nearby alternatives keep it honest.
Cartboy is not trying to win every argument at once; its appeal lives in the balance between emulation comfort, day-to-day usability, and whether its price still feels sane.
Before the review gets opinionated, here is the clean spec picture. This table is the reality check that keeps the rest of the write-up grounded.

If this review pulls you in, the fastest next rabbit hole is RG-NANO and TinyPi Pro, because those are the products most likely to clarify whether Cartboy is your real match or just your current curiosity.
Cartboy is best framed as a machine for players who care about nostalgia, portability, and quick pick-up sessions. This category rewards shoppers who know what kind of sessions they actually play, because not every strong device is strong in the same way.
The micro vertical shape matters here because it changes comfort, portability, and the kind of nostalgia the device leans into. The fact that it runs Linux - CartOS (RetroPie based) also affects what kind of setup work, app ecosystem, and tinkering ceiling buyers should expect.
The release timing listed as 2020 / 01 helps place it in context. In this market, timing changes expectations: a device that felt expensive at launch can look sharply judged six months later, while a newer device may need to justify a premium.
Cartboy is described with battery: 1200 mAh. Those are not background details; they shape noise, comfort, endurance, and whether the device feels eager to be used or mildly exhausting to keep fed. Audio is covered by Dual Stereo Front facing and 3.5mm Headphone, which matters for sofa play, travel, and late-night sessions when speakers and headphone output can quietly make or break the experience.
Physically, the device is outlined by 65.5 mm x 57 mm x 15 mm, 80.0, Plastic, and Blue, Gray, Red, Green, Orange. This is where you start picturing whether it is truly pocketable, only jacket-safe, or clearly a bag companion. Buyers often underestimate how much daily affection is driven by the little things: where the ports sit, how the shell feels, and whether the handheld seems built for real use instead of product photos.
The practical I/O story includes External MicroSD, USB OTG, Micro USB x2, and Mini HDMI. These details matter because many retro buyers are also collectors, tinkerers, dock-and-TV players, or people with large libraries that need sensible storage and transfer options.
Cartboy pairs the hardware with 1.3 inch, TFT, 60 Hz, 240 x 240, 1:1, and 261.09 PPI. That is the kind of detail stack retro buyers should linger on, because a handheld can be technically capable and still feel wrong if the aspect ratio, sharpness, and scaling story are off. The screen protection is listed as None (Protector only), a small clue that often hints at how polished or rough the front face might feel in daily use.
The controls are described with Cross Lower placement, 4 Butons, L1, R1, and Power. That matters more than many spec sheets admit, because the difference between a fun handheld and a fatiguing one often shows up in the D-pad, shoulder shape, and how naturally the thumbs settle into place. If the screen is what sells a handheld in screenshots, the controls are what decide whether it earns repeat sessions.
The 1:1 aspect ratio adds another layer to the story. Retro gaming screens are never neutral. They reward some libraries, punish others, and always whisper a preference about how the device expects to be used.
| Console | Angle | Price | Performance | Why Click Through |
|---|---|---|---|---|
RG-NANO Anbernic | Better Value | $60 (+ shipping) | ⭐️⭐️⭐️ | micro vertical layout, tracked around $60 (+ shipping), rated ⭐️⭐️⭐️. |
TinyPi Pro Pi0cket | Better Value | TBD | ⭐️⭐️⭐️ | micro vertical layout, rated ⭐️⭐️⭐️. |
GKD Pixel Game Kiddy | Better Value | 76.0 | ⭐️⭐️⭐️¼ | micro vertical layout, tracked around 76.0, rated ⭐️⭐️⭐️¼. |
GKD Pixel 2 Game Kiddy | More Powerful | 80.0 | ⭐️⭐️⭐️⭐️½ | micro vertical layout, tracked around 80.0, rated ⭐️⭐️⭐️⭐️½. |
Cartboy becomes much easier to judge once it is forced into the same room as RG-NANO, TinyPi Pro, and GKD Pixel. This is where a vague impression turns into a real buying decision, because each nearby rival throws a different kind of pressure on the table.
Cartboy versus RG-NANO is interesting because better value is the obvious angle. RG-NANO sits close enough to Cartboy to make the comparison meaningful, but different enough to sharpen the buying decision. RG-NANO is tracked around $60 (+ shipping). Its overall rating is ⭐️⭐️⭐️. Cartboy versus TinyPi Pro is interesting because better value is the obvious angle. TinyPi Pro sits close enough to Cartboy to make the comparison meaningful, but different enough to sharpen the buying decision. Cartboy versus GKD Pixel is interesting because better value is the obvious angle. GKD Pixel sits close enough to Cartboy to make the comparison meaningful, but different enough to sharpen the buying decision. GKD Pixel is tracked around 76.0. In practice, its overall rating is ⭐️⭐️⭐️¼.
A handheld earns a place in the shortlist when it can survive comparison without needing excuses. That is the standard this section is really applying.
Cartboy is currently tracked around $100 (DIY) $200 (Pre-built) and lands in the $100 - $150 pricing band. Price does not just change whether a device feels affordable. It changes what kinds of flaws buyers are willing to forgive.
The spreadsheet points shoppers toward Gamebox Systems for availability. That matters because storefront quality, shipping confidence, and after-sales expectations often shape the emotional experience of a purchase before the box even arrives. The listed strengths orbit around portability.
The tradeoffs are not buried, either: the sheet flags price, tiny screen. That is why value is always a conversation between specs and priorities. There is no universal bargain, only a good fit at the right moment.
The heart of the machine is the Broadcom BCM2835 (Raspberry Pi Zero). CPU duties are handled by ARM1176JZF-S. Graphics are handled by Broadcom VideoCore IV. Memory is listed at 512 MB DDR. The sheet rates the overall performance at ⭐️⭐️⭐️, or roughly 3 on the normalized scale.
The CPU side is described with 1 Core, 1 Thread, and 1.0 GHz, which is more useful than brand names alone because it hints at how much headroom the handheld should have before emulator tuning gets annoying. On the graphics side, 250 MHz and ARM helps sketch the ceiling for heavier systems, upscale experiments, and shader curiosity.
Cartboy looks strongest with Game Boy (A), NES (A), Sega Genesis (A), and Game Boy Advance (B), which gives the review something more tangible than a vague "good for retro" verdict. The listed emulation limit, Most SNES runs at 60 FPS but lags with FX & Mode 7 games, most 2D PS1 runs fine (not all at full 60 FPS) but lags with 3D games, is the kind of line buyers should actually respect because it tells you where the romance ends and the compromise begins.
The middle tier of compatibility, including Super Nintendo (C) and PlayStation 1 (C), is where the buyer needs some honesty. These are usually the systems that separate a casual dabbler from a user who is happy tweaking emulator settings, testing cores, or accepting the occasional rough edge.
Cartboy leaves the strongest impression when you frame it as a recommendation for players who care about nostalgia, portability, and quick pick-up sessions. That is the lens that makes the strengths feel intentional instead of accidental.
Budget shortlist candidate is not just a catchy label here. It is the cleanest shorthand for why this device deserves attention. The compatibility profile around Game Boy (A), NES (A), Sega Genesis (A), and Game Boy Advance (B) gives it a concrete identity. The main caution remains price, tiny screen.
If the device sparks your interest, the smartest next click is usually RG-NANO, followed by TinyPi Pro, because that is where the shape of the market around it comes into focus. The point is not to stop the reader from exploring. It is to make every next click smarter.
Games shown here match systems this handheld can run at a B grade or better.
