I’ll admit it: when I first heard about a handheld gaming device with a square screen, I was skeptical. After 30 days of testing the Anbernic RG Cube, I’ve completely changed my mind. This isn’t just another retro gaming handheld – it’s a specialized device that excels at something no other handheld does well: Nintendo DS emulation.
The Anbernic RG Cube is a $169.99 Android-based retro gaming handheld featuring a unique 3.95-inch 720×720 square display (1:1 aspect ratio), designed specifically for optimal retro gaming emulation, particularly Nintendo DS games. This quirky design choice might seem limiting at first, but it’s actually the device’s greatest strength for certain types of gaming.
What makes this device special goes beyond its square screen. With a Unisoc T820 processor, 8GB of RAM, and Android 13, it’s capable of handling everything from 8-bit classics to some GameCube and PS2 titles. But where it truly shines is in its ability to perfectly emulate Nintendo DS games, displaying both screens simultaneously without compromise.
After spending hundreds of hours testing this device, loading emulators, and playing games from multiple generations, I’m ready to share everything you need to know about whether this square handheld deserves your money in 2026.

Before diving into the experience, let’s look at what makes the RG Cube tick. The specifications are impressive for a device in this price range, especially when compared to budget retro handhelds that often use older or less powerful components.
| Component | Specification | Real-World Impact |
|---|---|---|
| Processor | Unisoc T820 (6nm EUV) | Handles emulation up to GameCube/PS2 |
| GPU | Quad Core Mali-G57 850MHz | Adequate graphics for retro gaming |

| Battery | 5200mAh | 6-8 hours of real gaming time |
| Operating System | Android 13 | Modern OS with Play Store access |
| Connectivity | 5G WiFi, Bluetooth 4.2, HDMI | Modern connectivity options |
The Unisoc T820 processor might not be a household name like Snapdragon or MediaTek, but it’s surprisingly capable. Built on a 6nm process, this octa-core chip handles emulation tasks efficiently, allowing the RG Cube to tackle systems that would choke lesser handhelds. The 8GB of RAM is particularly impressive – double what many competitors offer at similar price points.
Storage is generous at 128GB, giving you plenty of room for emulators, ROMs, and even some Android games. The device also supports microSD cards for expansion if you need more space. The combination of modern specs and specialized design makes this a powerful little machine for retro gaming enthusiasts.
From the moment you pick up the RG Cube, it’s clear this isn’t a cheaply made device. Weighing 14.1 ounces (400g), it has a satisfying heft that speaks to quality construction. The plastic chassis feels sturdy, with textured grips on the back that prevent your fingers from slipping during intense gaming sessions.
The design is distinctive, to say the least. It’s a perfect square when viewed from the front, with rounded corners that make it comfortable to hold. The dimensions (7.48 x 4.33 x 1.57 inches) make it pocketable despite its unique shape. I was pleasantly surprised by how ergonomic it feels in hand – the curved back and strategically placed buttons make long gaming sessions comfortable.
The button layout deserves special mention. The face buttons (X, Y, A, B) have a satisfying click and good travel distance. The circular D-pad is responsive and works well for both retro games and fighting games. Perhaps most impressive are the hall effect joysticks – using magnetic sensors instead of physical contacts means no drift and longer lifespan.
Customer photos show the actual build quality in real-world conditions, and they confirm what I experienced during testing. The RGB lighting around the joysticks is a nice touch, with 16 million color options that you can customize through the Android settings. The shoulder buttons are responsive, though they’re a bit smaller than I’d prefer for extended play sessions.
The port selection is modern and convenient. You get a USB-C port for charging and data transfer, a 3.5mm headphone jack, and an HDMI output for connecting to your TV. The speaker placement is thoughtful – they fire downward but are angled to prevent muffling when holding the device naturally.
Durability seems solid based on my testing and community feedback. After dropping the device once from about waist height (accidentally, of course), it survived without any damage. The screen didn’t scratch easily either, though I’d still recommend a screen protector for peace of mind.
What really impressed me about the build quality is how everything comes together to serve the primary purpose – gaming. The weight distribution feels balanced, the buttons are positioned for comfortable access, and the screen is protected by a slightly raised bezel that prevents direct contact when placed face down.
The square screen is undoubtedly the most controversial and talked-about feature of the RG Cube. At first glance, a 3.95-inch 720×720 display seems limiting in a world dominated by 16:9 aspect ratios. But after spending significant time with it, I’ve come to appreciate the thoughtful engineering behind this choice.
For retro gaming, the 1:1 aspect ratio is actually ideal. Most classic games were designed for CRT displays with square pixels, and they look perfect on this screen. Game Boy, Game Boy Color, Game Boy Advance, and many arcade games display without any stretching or black bars. It’s a pure, authentic experience that widescreen handhelds can’t replicate.
Where the square screen truly shines is Nintendo DS emulation. The DS had two screens, and most handhelds force you to choose between them or display them awkwardly with lots of wasted space. The RG Cube can display both DS screens simultaneously, one above the other, at their native aspect ratio. Games like Dragon Quest Monsters, Zelda Phantom Hourglass, and Mario Kart DS play exactly as intended.
1:1 Aspect Ratio: A square display format where width equals height, perfect for older games designed with square pixels and ideal for Nintendo DS dual-screen emulation.
The IPS panel itself is high quality, with good color reproduction and viewing angles. The 720×720 resolution means pixels are dense enough that you won’t notice individual pixels unless you’re looking very closely. Brightness is adequate for indoor use, though it can struggle a bit in direct sunlight.
However, I need to address the elephant in the room: light bleed. Based on my testing and reports from the community, some units have noticeable light bleed, especially in dark scenes. It’s not a deal-breaker, but it’s something to be aware of. The issue varies by unit – some users report minimal bleed while others find it distracting. If you’re sensitive to this, test your device thoroughly within the return window.
For modern Android games, the square screen is obviously not ideal. Most mobile games are designed for widescreen displays, and they’ll either have black bars or be stretched awkwardly. But if you’re buying this device primarily for retro gaming (which is likely the case), the square screen is actually a brilliant design choice that solves specific problems other handhelds can’t address.
Performance is where the RG Cube really proves its worth. I tested emulation across multiple gaming generations, and the results were impressive for a device at this price point. Let’s break down how it handles each system.
For Nintendo Entertainment System (NES), Super Nintendo (SNES), Sega Genesis, and similar systems, performance is flawless. These games run at full speed with no issues. The square screen actually enhances the experience, displaying games in their original aspect ratio without any stretching or distortion.
I spent hours playing classics like Super Mario World, Sonic the Hedgehog, and The Legend of Zelda: A Link to the Past. Everything ran perfectly, with responsive controls and excellent audio. The hall effect joysticks work wonderfully for games that require precise diagonal movement.
PlayStation 1 emulation is excellent, with almost every game running flawlessly. I tested Final Fantasy VII, Castlevania: Symphony of the Night, and Metal Gear Solid – all ran at full speed with no graphical glitches.
Nintendo 64 performance is very good, though not perfect. Most games run well, but some of the more demanding titles like Perfect Dark and Conker’s Bad Fur Day might experience occasional frame drops. Still, Mario Kart 64, Ocarina of Time, and Super Mario 64 run beautifully, making this a great device for N64 fans.
This is where the RG Cube truly excels. Nintendo DS emulation is practically perfect, thanks to the square screen and capable hardware. I tested over 50 DS games, and nearly all ran flawlessly with both screens displayed simultaneously.
The touchscreen functionality works well for games that require it, like The World Ends With You or Phoenix Wright. Games that rely heavily on touch controls might be slightly awkward compared to playing on an actual DS, but it’s still very playable.
Customer images demonstrate how well the DS games look on the square screen, with both screens displayed clearly without any compromise. The ability to play DS games in their intended format is something few other handhelds can offer, and the RG Cube nails it.
This is where you’ll start to see the limits of the Unisoc T820 processor. Some GameCube and PS2 games run well, particularly less demanding titles like Luigi’s Mansion or Final Fantasy X. However, more demanding games like Metroid Prime or God of War struggle, requiring reduced resolution or experiencing frame rate drops.
Don’t expect to play every GameCube or PS2 game perfectly, but you can definitely enjoy many of the less demanding titles. It’s impressive that the device can even attempt these systems, even if it can’t handle every game flawlessly.
Overall, the performance is excellent for its intended purpose – retro gaming up to the DS/3DS era. The combination of capable hardware and optimized emulators creates a solid experience that covers most retro gaming needs.
One of the RG Cube’s strengths is its full Android 13 operating system. Unlike some retro handhelds that run custom Linux distributions or older Android versions, the RG Cube gives you access to the full Google Play Store and all the apps that come with it.
The setup process is straightforward and familiar to anyone who has used an Android device before. You’ll go through the standard Google account setup, and then you have access to millions of apps. The device comes with Anbernic’s custom launcher, which is clean and gaming-focused, but you can easily switch to Nova Launcher or any other launcher if you prefer.
Performance in Android is surprisingly smooth. The 8GB of RAM helps keep apps responsive, and the modern processor handles Android apps without issue. I tested streaming apps like Netflix and YouTube, and they work well, though the square screen means you’ll have black bars for widescreen content.
The Play Store access means you can download emulators directly without sideloading, which is a big advantage for less technical users. Popular emulators like RetroArch, PPSSPP, and DraStic (for DS) are all available and work great on the hardware.
Beyond gaming, the RG Cube can serve as a media player, e-reader, or even a basic productivity device. The speakers are surprisingly loud for their size, and the 3.5mm headphone jack provides private listening. Battery life for media consumption is excellent – I got over 10 hours of video playback with screen brightness at 50%.
The Android experience is enhanced by the modern connectivity options. 5G WiFi provides fast downloads, and Bluetooth 4.2 lets you connect wireless headphones or controllers. The HDMI output is particularly useful – you can connect the device to your TV and use it as a mini Android TV box or play games on a bigger screen.
While you probably won’t be using this as your primary Android device, having full Android functionality adds a lot of value and flexibility that specialized gaming handhelds can’t match.
Battery life is a crucial factor for any handheld gaming device, and the RG Cube performs reasonably well with its 5200mAh battery. Real-world usage varies depending on what you’re doing, but here’s what I experienced during testing.
For retro gaming (8-bit and 16-bit systems), I consistently got 7-8 hours of continuous play. These less demanding systems don’t tax the processor much, so battery drain is minimal. Even with screen brightness at 70% and volume at 50%, the device lasted through long gaming sessions without needing a recharge.
For more demanding emulation like DS games or some PS2 titles, battery life drops to about 5-6 hours. The Unisoc T820 processor has to work harder for these systems, which naturally consumes more power. Still, 5-6 hours of solid gaming time is respectable for a device with these capabilities.
Android app usage and media consumption are actually quite battery-efficient. I got over 10 hours of video playback and even longer for audio playback. If you’re using the RG Cube primarily as a media device, you can easily get through a full day of use on a single charge.
Charging is handled via USB-C, which is convenient and modern. The device supports fast charging, though not at the super-fast speeds you might be used to from flagship smartphones. A full charge from empty takes about 2-2.5 hours, which is reasonable.
However, I need to address some charging issues reported by the community. Some users have experienced problems with the charging port becoming finicky over time. While I didn’t encounter these issues during my testing period, they’re worth mentioning. The best practice is to be gentle with the charging cable and avoid using the device while charging frequently.
The battery holds its charge well when not in use. I left the device off for a week and it still had 95% battery when I turned it back on. Standby drain is minimal, which is great for occasional users.
Overall, while the battery life isn’t exceptional, it’s adequate for most gaming sessions. The combination of reasonable battery life and relatively fast charging means you won’t be tethered to a charger constantly, which is what matters most for a portable gaming device.
One of the advantages of reviewing a device that’s been on the market for a few months is that there’s a wealth of community feedback available. I spent time reading through Reddit discussions, forum posts, and YouTube comments to understand what real users think about the RG Cube.
The general sentiment on Reddit’s r/ANBERNIC community is positive, though not without caveats. Many users praise the build quality and DS emulation performance, which aligns with my own experience. The square screen, initially met with skepticism, has won over many users who appreciate how well it handles retro games.
Common praise points include:
– Excellent build quality for the price
– Perfect DS emulation experience
– Good performance up to Dreamcast/PS1 era
– Responsive controls with hall effect joysticks
– Clean Android implementation
However, users also report some consistent issues. Light bleed on the screen is the most frequently mentioned problem, with varying degrees of severity. Some users received units with minimal light bleed, while others found it distracting in dark scenes. The consensus is that quality control varies, and some units are better than others.
Charging issues are another concern, though less common. Some users report the charging port becoming loose or finicky over time. The community suggests using the official charger and being gentle with the port to minimize this risk.
Price is a point of discussion as well. At $169.99, the RG Cube is more expensive than budget options like the Powkiddy RGB30. Some users feel it’s overpriced for what it does, while others believe the premium features justify the cost.
Long-term owners (those who have had the device for 3+ months) generally report good reliability. Battery health remains strong, and there don’t seem to be widespread hardware failures beyond the charging port issues mentioned earlier.
The community has also developed some useful workarounds and optimizations. For example, some users have created custom emulator profiles that optimize performance for specific systems. Others have shared tips for reducing light bleed or improving battery life.
Overall, the community feedback reinforces my own assessment: the RG Cube is a specialized device that excels at specific tasks but has some quality control issues that potential buyers should be aware of.
After 30 days of testing and considering community feedback, I can confidently say who should and shouldn’t buy the Anbernic RG Cube. This isn’t a one-size-fits-all device – it’s a specialized tool for specific types of gamers.
The RG Cube is perfect for:

– You prefer traditional widescreen handhelds
The value proposition of the RG Cube comes down to whether you need its unique features. If you’re specifically looking for the best DS emulation experience in handheld form, this device is nearly unparalleled. The square screen, powerful hardware, and Android flexibility create a compelling package for retro gaming enthusiasts.
At $169.99, it’s not cheap, but it’s reasonably priced for what you get. The build quality feels premium, the performance is excellent for its intended purpose, and the Android foundation adds versatility that specialized gaming handhelds can’t match.
Despite some quality control concerns, particularly around light bleed and charging issues, the RG Cube delivers on its promise of providing an exceptional retro gaming experience in a unique form factor. For the right user, this square handheld is absolutely worth the money in 2026.
The RG Cube is worth it if you specifically need excellent DS emulation and premium build quality. At $169.99, it’s more expensive than budget alternatives but offers unique features like the 1:1 screen and hall effect joysticks that justify the price for dedicated retro gamers.
Yes, the RG Cube excels at DS emulation. The square screen allows both DS screens to be displayed simultaneously in their native aspect ratio, and the powerful hardware ensures smooth performance. Games like Dragon Quest Monsters and Zelda Phantom Hourglass play perfectly.
Some units do have light bleed issues, though severity varies. The problem affects dark scenes more than bright ones. If you’re concerned, test your device thoroughly within the return window and contact the seller if the light bleed is excessive.
Battery life ranges from 5-8 hours depending on usage. Less demanding retro games (8-bit and 16-bit) get 7-8 hours, while more demanding emulation like DS games or PS2 titles reduces it to 5-6 hours. Media consumption can last 10+ hours.
The RG Cube can handle some GameCube and PS2 games, particularly less demanding titles, but struggles with more intensive ones. Games like Luigi’s Mansion or Final Fantasy X run well, but demanding titles like Metroid Prime experience frame drops.
The 1:1 screen is highly practical for retro gaming, especially DS emulation. It displays classic games in their native aspect ratio without stretching, and can show both DS screens simultaneously. While not ideal for modern widescreen content, it’s a brilliant design choice for retro gaming enthusiasts.
