Choose the Retroid Pocket 4 if Nintendo 3DS is important to you. CompareHandhelds rates Nintendo 3DS as unsupported on the R36S and fair on the Retroid Pocket 4, while HandheldDatabase lists the Pocket 4 as playable. Those are platform-level ratings, not guarantees for every game, but they establish the practical choice: the R36S is an inexpensive handheld for older systems, whereas the Pocket 4 is the only realistic 3DS option of the two.
The reason is more than processor speed. The Pocket 4 combines a substantially faster chipset, four times the memory, Android app support, a touchscreen, a gyroscope, analog triggers and Hall-effect sticks. The R36S is smaller, lighter and naturally shaped for 4:3 8-bit, 16-bit and PlayStation 1 games, but its hardware and controls are not designed around 3DS emulation.

Nintendo 3DS performance and compatibility
Why the R36S is not a 3DS purchase
The R36S uses a Rockchip RK3326 with four Cortex-A35 cores, a Mali-G31 MP2 GPU and 1 GB of DDR3L RAM. CompareHandhelds classifies Nintendo 3DS as unsupported on this hardware. That rating is consistent with the R36S’s intended role: ArkOS and RetroArch are configured around older systems rather than the substantially more demanding 3DS generation.
Installing a different menu, changing a RetroArch setting or replacing the microSD card does not change the underlying processor, graphics capability or memory capacity. You may find experimental software references online, but an unsupported platform rating should be treated as a stop sign for a 3DS-focused purchase.
What “fair” and “playable” mean on the Pocket 4
The Pocket 4 is not a promise that every 3DS title will run smoothly. CompareHandhelds gives it a fair rating, and HandheldDatabase lists it as playable. These labels indicate that 3DS emulation is feasible on the device, with results depending on the game, emulator build, graphics settings and any per-title fixes.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteThe safest expectation is that some games will be comfortable while others may need lower resolution, frame-skip or other adjustments. The available material does not provide a standardized per-game benchmark or an emulator-version matrix, so no honest comparison can guarantee a fixed frame rate or identical behavior across the library.
Why the Pocket 4 has the necessary headroom
Retroid lists a Dimensity 900 system-on-chip with two Cortex-A78 cores at 2.4 GHz, six Cortex-A55 cores at 2.0 GHz, Mali-G68 MC4 graphics at 900 MHz and 4 GB of LPDDR4X RAM. Compared with the R36S’s RK3326 and 1 GB of DDR3L, this is a major increase in CPU performance, graphics resources and available memory. That gap explains why the Pocket 4 reaches newer systems while the R36S is best kept to older retro consoles.

Controls, touch and motion input
Why 3DS control requirements matter
Nintendo 3DS games were designed around a lower touchscreen, a second display, a circle pad, face buttons, shoulder buttons and, for some titles, motion sensing. A device can have enough processing power yet still be awkward if it cannot reproduce those inputs.
Retroid Pocket 4 advantages
- The 4.7-inch touchscreen provides direct input for menus, maps, inventory screens and touch-driven game actions.
- A built-in gyroscope supports motion features that would otherwise require a workaround.
- Analog L2 and R2 triggers provide graduated input rather than simple on/off shoulder-button presses.
- Three-dimensional Hall-effect sticks are designed to resist the wear associated with traditional potentiometer sticks.
These features do not guarantee that an emulator maps every game perfectly, but they remove several hardware obstacles that the R36S cannot address.

The R36S has a 3.5-inch 4:3 IPS panel with no documented touch input. Its physical controls are well matched to classic systems, but a 3DS title that expects stylus taps or motion control will require compromises. You can assign touch actions to buttons only where the emulator permits it, and that can make games built around the touchscreen considerably less convenient.
Displays: one screen versus the 3DS layout
R36S: excellent proportions for classic games
The R36S’s 3.5-inch, 640×480 IPS panel uses a 4:3 aspect ratio. That shape suits many 8-bit, 16-bit and PlayStation 1 games with minimal wasted space. It also keeps the vertical handheld compact and light.
Pocket 4: larger, sharper and widescreen
Retroid specifies a 4.7-inch touchscreen with 750×1334 resolution, 60-fps operation and 500-nit brightness. Its approximately 16:9-class shape gives Android interfaces and modern systems more room, although older 4:3 games can display black bars at the sides.

Neither device has two physical panels. On the Pocket 4, the emulator must present both 3DS screens on one display, switch between them, or use a custom layout. A larger screen and touch input make that arrangement more usable, but it is still not the same viewing experience as original 3DS hardware. The R36S’s smaller 4:3 panel offers no special advantage for this two-screen problem.
Processing hardware and what it changes in practice
| Specification | R36S | Retroid Pocket 4 |
|---|---|---|
| CPU architecture | Quad-core Cortex-A35 | 2× Cortex-A78 at 2.4 GHz plus 6× Cortex-A55 at 2.0 GHz |
| GPU | Mali-G31 MP2 | Mali-G68 MC4 at 900 MHz |
| RAM | 1 GB DDR3L | 4 GB LPDDR4X |
| Cooling | Not stated in the supplied specifications | Active cooling listed by Retroid |
For older emulators, the R36S hardware is usually sufficient and its lower demands help explain its lower price. 3DS emulation performs more work per frame, including translating the original system’s CPU and graphics behavior. The Pocket 4’s newer big cores, faster graphics and larger memory pool give an emulator more room to maintain performance and run an Android operating system at the same time.
Battery life, weight and portability
R36S: the pocketable budget choice
The R36S is smaller and lighter than the Pocket 4, and its vertical body is easy to carry. The vendor advertises up to five hours of play. That is a usage claim rather than a laboratory result; brightness, volume, emulator, game and wireless activity all change runtime. CompareHandhelds reports longer average battery life for the R36S than for the Pocket 4, but those figures are source-specific estimates, not a controlled test that applies to every owner.
Pocket 4: more battery capacity, more demanding hardware
The Pocket 4 has a 5,000 mAh battery and active cooling. Its larger screen and faster processor add capability but also increase the power budget. The available comparison does not establish a universal number of hours for 3DS play, so plan around access to charging rather than assuming the 5,000 mAh figure translates directly into a particular session length.
Choose the R36S when the smallest possible retro companion matters more than newer-system support. Choose the Pocket 4 when you accept extra weight in exchange for a larger screen, better controls and the processing margin needed for 3DS.

Operating system, connectivity and storage
ArkOS and RetroArch on the R36S
The R36S uses ArkOS with RetroArch. This gives it a console-like interface for classic systems and established emulator cores. USB-C is used for charging, and storage is expandable with a card. The platform is intentionally streamlined; it is not an Android tablet with access to a broad app ecosystem.
Android 11 on the Pocket 4
The Pocket 4 ships with Android 11, supports over-the-air updates and can install compatible Android applications. Retroid lists Wi-Fi 6, Bluetooth 5.2, video out and TF-card storage expansion. Android makes it possible to use a compatible 3DS emulator and configure touch overlays, controller mappings and display layouts, although the exact experience depends on the emulator version and the game.
Planning storage expansion
Both devices support expandable storage, so a larger card can hold more legally obtained game backups, save files and emulator data. Card capacity, file-system format and the emulator’s directory permissions can affect setup. Back up the card before changing its partitions or replacing preinstalled files, and keep a separate copy of save data.

The following workflow avoids assuming a particular emulator release. Menus and names can change between Android applications, so use the instructions supplied by the emulator you install.
- Update the handheld. Connect the Pocket 4 to Wi-Fi, open its system update tool and install any available Android or Retroid update before configuring games.
- Prepare storage. Insert a compatible TF card if you need more space. Format it through Android only after copying off any files you want to keep.
- Install a compatible Android 3DS emulator. Use a reputable, current source and check that its Android version and processor requirements match the Pocket 4. The available comparison does not certify one specific emulator or version.
- Point the emulator to your game directory. Grant Android’s requested storage permission, then select the folder containing your own legally obtained game backups.
- Map the controls. Assign the Hall-effect sticks, face buttons, shoulder buttons and analog triggers. Test the touchscreen and gyro in the emulator’s input panel before launching a game.
- Choose a screen layout. Try side-by-side, stacked or touch-focused layouts. The 4.7-inch widescreen panel cannot display two full-size 3DS screens at their original proportions simultaneously, so choose the arrangement that keeps the active screen readable.
- Start with conservative graphics settings. Use the emulator’s native or lower internal resolution first. Raise resolution only after a title is stable, and change one option at a time so you can identify the cause of slowdowns or glitches.
- Test each title separately. Record whether menus, audio, saves, touch actions and motion controls work. A setting that helps one game can hurt another.
Do not treat a single successful launch as proof that the entire 3DS library is supported. The published ratings are broad platform guidance, and the available evidence does not include a controlled game-by-game test.

What the R36S is actually good at
Although it loses this comparison on 3DS, the R36S can be the better product for a different brief. Its 4:3 screen, low weight and ArkOS interface suit 8-bit and 16-bit consoles, arcade titles and PlayStation 1-era games. If those systems make up most of your library, paying for the Pocket 4’s Android hardware may add cost and bulk without improving the games you play.
The R36S vendor says, “The R36S gives you access to over 20,000 retro games ready to play: RPG, fighting, adventure, arcade and more.” That is a vendor marketing claim, not an independently audited count, so evaluate the hardware and software rather than buying on the number alone.
Price and value
CompareHandhelds reports the R36S as about $100 cheaper than the Retroid Pocket 4 in its comparison snapshot. That is useful for understanding the tier difference, not a guaranteed current price. Retail pricing, promotions and stock change, and the available material does not establish a recurring price for either model.

For a 3DS-focused buyer, the extra cost of the Pocket 4 pays for the only platform in this pair rated for 3DS, plus touchscreen and motion input, a faster Dimensity 900 chip, 4 GB of RAM, Android app support and broader connectivity. For a buyer who wants inexpensive classic gaming, the R36S preserves money and pocket space by omitting capabilities that may never be used.
Decision guide
Buy the Retroid Pocket 4 if:
- Nintendo 3DS is a central requirement rather than an occasional experiment.
- You want the best chance of playable results across a varied 3DS library, while accepting title-by-title tuning.
- You need touchscreen and gyroscope input.
- You prefer Android apps, Wi-Fi 6, Bluetooth 5.2, video out and OTA updates.
- A larger 16:9-class screen is more useful to you than the R36S’s 4:3 panel.
Buy the R36S if:
- Your library is primarily 8-bit, 16-bit, arcade or PS1-era software.
- You want the smallest and lightest option and do not need a touchscreen.
- Your budget is tight and 3DS support would be a bonus rather than a requirement.
- You prefer a focused ArkOS/RetroArch interface over Android.
Common mistakes and how to avoid them
- Buying by screen size alone: A larger panel does not create two physical 3DS screens. Check the emulator’s layout options and expect compromises.
- Assuming “playable” means universal full speed: HandheldDatabase’s label and CompareHandhelds’ fair rating are platform-level guidance. Test the specific games you care about.
- Confusing storage with performance: A larger microSD card stores more files but does not upgrade the RK3326, Dimensity 900, GPU or RAM.
- Using one battery figure as a promise: The R36S’s up-to-five-hour statement is a vendor claim, and Pocket 4 runtime depends on workload. Brightness, volume, wireless use and emulator settings matter.
- Expecting an operating-system change to fix weak hardware: ArkOS settings cannot turn an unsupported R36S platform into a 3DS-capable device.
- Ignoring input mapping: Confirm touch, gyro, analog triggers and stick assignments before judging a game. A title can launch correctly and still be unplayable until its controls are mapped.
Final verdict
For Nintendo 3DS games, the Retroid Pocket 4 wins decisively. It is the only model here with a positive 3DS capability rating, and its Dimensity 900 processor, 4 GB RAM, touchscreen, gyroscope and modern controls explain why. Its single widescreen display still requires an emulator layout compromise, and compatibility remains game-dependent.
The R36S is the better value only when 3DS is not the point. Its lower price, lighter body, 4:3 screen and ArkOS/RetroArch setup make it a strong inexpensive retro handheld for older systems. Do not buy it expecting Nintendo 3DS support; spend extra on the Pocket 4 if that system is central to your plans.
