R36S Review: Great for $40, If You Get the Real One

Most R36S reviews answer a question nobody is really asking. Yes, a forty dollar handheld plays Game Boy and SNES well. Of course it does.

The question that actually matters is the one almost nothing online answers properly: which R36S are you going to receive? Because R36S is not a product made by a company. It is a shape and a name, applied to several genuinely different circuit boards by several unrelated sellers, and which board arrives in your box decides whether the thing that makes an R36S worth owning will work at all.

So this review is organised around that. What the good version is, how to tell what you got, and what to do if it is not the good version.

The Short Version

• The good one is a Rockchip RK3326 with 1GB of RAM, a 3.5 inch 640x480 IPS screen and a 3,500mAh battery. For 8 bit, 16 bit, Game Boy, Game Boy Advance and most of PS1, it is excellent and nothing near the price beats it.
• The clones use different chips entirely. The two documented families are an Allwinner H700 and an Allwinner A33, and at least one A33 board ships with half the RAM.
• Why that matters more than a spec sheet: the custom firmware community that makes the R36S good targets the RK3326. One clone firmware project states the problem plainly: no existing R36S custom firmware supports its board, because they all target the Rockchip chip.
• You can check in two minutes once the device arrives, and the checks are below.
• Nobody is accountable for any of it. There is no manufacturer, no warranty and no support line. That is priced in at forty dollars and it is still worth saying.
• It ships with a microSD card full of game files. We do not treat that as a feature and neither should you. Replacing that card is step one of owning this device for reasons that have nothing to do with what is on it.

Specs, for the Genuine Version

R36S Is a Name, Not a Product

This is the part to understand before you spend anything, and it explains every confusing thing you will read elsewhere.

There is no R36S company. There is a reference design, and a large number of sellers who order units from factories and list them under the same name. Over time, factories changed what they put inside the same shell. The result is that two devices that look identical, bought from two listings in the same week, can be different computers.

The documented families, as of November 2026:

Note the last row properly. That project's own documentation says its firmware works only on one specific board revision of that clone, and other revisions of the same clone may behave unexpectedly. So the fragmentation is not even one level deep. It goes down to board revisions within clone families.

How to Tell What You Got

Three checks, in order of how conclusive they are. Our R36S setup guide walks through all of them with the firmware step attached.

1. Read the system's own CPU field. A genuine unit reports a Rockchip part. An Allwinner H700 clone reports an identifier from the Allwinner family instead, which looks nothing like a Rockchip name.

2. Put the system microSD in a computer and read the partition names. A genuine unit running the community firmware has a partition named EASYROMS. The common clones show partition names from a different firmware base instead.

3. Look at the device tree files on the boot partition. This is the definitive check, because that file names the board. A genuine unit has a Rockchip device tree filename. Clones have filenames that do not mention Rockchip at all, or no device tree files at all.

Do check number three before you flash anything, and keep a copy of the file. The most common way people brick the experience is flashing an image for the wrong board, and the device tree file is how you avoid it and how you recover.

The Firmware Situation, and One Thing Every Other Guide Gets Wrong

Here is the finding that changes the advice, and it is a few months old.

ArkOS is archived. The custom firmware that essentially every R36S guide, video and forum post tells you to install was archived by its own developer, with its last update in August 2025. It is not being maintained. Searching "R36S ArkOS" in 2026 returns a great deal of writing that silently assumes a project that has stopped.

dArkOS is the successor and it is active, with commits in November 2026. It is a Debian based rebuild by the same developer. The R36S line of it circulates as a device-specific release, and there is a separate build for supported clones.

This matters because firmware is the entire argument for this device. A forty dollar handheld with a vendor build is mediocre. A forty dollar handheld with current community firmware, properly configured, punches far above its price. If you follow a 2024 guide to a 2025 archive, you get the mediocre version and conclude the device is mediocre.

What It Actually Plays

The RK3326 is a 2018 class chip and the honest performance picture is narrower than the marketing.

Excellent: NES, SNES, Mega Drive, Master System, Game Boy, Game Boy Color, Game Boy Advance, PC Engine, Neo Geo, arcade up to the mid 1990s. This is most of what people buy a device like this for and it is all comfortable.

Good: PlayStation 1. Most of the library runs well, with the heaviest 3D titles being the exception rather than the rule. A 640x480 screen also treats PS1 kindly.

Patchy: Nintendo 64 and Dreamcast. Some games run, most do not run well, and the ones that do often need per game settings. Do not buy this device for either.

No: PSP, Nintendo DS in any comfortable sense, and anything newer. PSP in particular is advertised constantly on these listings and it does not work in a way you would enjoy.

The screen is the quietly excellent part. 640x480 in 4:3 is a whole number multiple of several classic systems' output, which means pixel art can be displayed without resampling. That is a nicer property than a bigger, higher resolution panel at an awkward ratio.

The Preloaded Card

Every one of these ships with a microSD card full of game files, and sellers advertise a game count as the headline feature.

We do not treat that as a feature and this review gives it no credit. Everything on this site is written for people playing games they own, and that is the frame here too.

There is also a practical reason to replace that card immediately, separate from what is on it. The stock card is the single most common point of failure on this device. They are the cheapest cards the bill of materials allows, in a device where the card is the system drive. A card that fails takes your saves with it.

So: buy a card from a brand you recognise, image the system onto it yourself, and keep the original untouched in a drawer as your record of which board you received. Our best microSD cards guide covers buying one that is what it claims to be, and the microSD corruption guide covers the failure signs.

Build, Battery and the Charging Trap

The shell is plastic and feels like forty dollars. The buttons and d-pad are better than they have any right to be, which is most of why this device has the reputation it does. The base model has no analog sticks, which rules out a few systems and matters less than you would think for everything before PS1.

The battery is replaceable with a standard connector, and replacements are a few dollars. For a device with no manufacturer behind it, user replaceable is worth more than capacity.

The charging trap is worth a paragraph of its own, because it generates a lot of "my R36S will not turn on" reports that are not faults.

The base R36S lacks the resistors a USB-C to USB-C cable needs to negotiate power. Plug a modern phone charger with a USB-C to USB-C cable into it and nothing happens. The device looks dead. It is not. Use a plain USB-A to USB-C cable with an ordinary 5V charger and it charges normally. Also use the port labelled for power rather than the data port.

Who Should Buy One

Buy an R36S if you want a cheap, genuinely good handheld for systems up to PS1, you are comfortable replacing a microSD card and flashing an image, and you accept that which board you receive is a lottery you can only resolve after it arrives.

Buy something else if you want any of PSP, DS, Dreamcast or N64, you want Wi-Fi for RetroAchievements or netplay, or you want a company to answer an email when something breaks. An Anbernic RG35XX H costs a little more, has a manufacturer behind it, and removes the board lottery entirely. Our best handhelds under $50 covers the whole tier.

Do not buy a rebranded one. The same hardware is resold through social media advertising at two to four times the price under invented brand names, with spec claims the chip cannot meet. We documented one in detail in our Retroverse Pro 2.0 review.

Final Verdict

Three and a half stars, and the half star it loses is not about the hardware.

For forty dollars, a genuine R36S with current firmware and a decent card is the best value in handheld gaming. We would recommend it to anybody without hesitating, if we could guarantee that is what arrived.

We cannot, and that is the review. The name covers several different computers, the firmware that makes it good runs on one of them, and you find out which one you bought after you have bought it. If that is a game you are happy to play for forty dollars, play it. If it is not, fifty to sixty dollars buys a device with a manufacturer's name on the box.

Frequently Asked Questions

Is the R36S worth buying in 2026?

Yes, if you get a genuine Rockchip RK3326 unit, replace the stock microSD card and install current community firmware. Under those three conditions nothing at the price beats it for 8 bit through PS1. The first condition is the problem, because several different boards ship under the R36S name and you cannot tell which you are getting from a listing.

How do I tell if my R36S is real or a clone?

Three checks. Read the system's CPU field, where a genuine unit reports a Rockchip part and the common clones report an Allwinner identifier. Put the system card in a computer and read the partition names, where a genuine unit shows EASYROMS. And look at the device tree file on the boot partition, which names the board outright and is the definitive answer. Do the third check before flashing anything and keep a copy of that file.

Does the R36S play PSP games?

Not in a way you would enjoy, despite being advertised for it constantly. The RK3326 is a 2018 class chip. PSP, Nintendo DS, Dreamcast and N64 are all either unplayable or need per game fiddling for mixed results. Buy this device for systems up to and including PlayStation 1.

Is there an Anbernic R36S?

No. Anbernic does not make the R36S and has never sold one. The R36S has no manufacturer at all, which is the root of everything else on this page. Anbernic's device in the same price range is the RG35XX family.

Why will my R36S not turn on or charge?

Most often because of the cable rather than a fault. The base R36S lacks the resistors a USB-C to USB-C cable needs to negotiate power, so a modern phone charger with a C to C cable does nothing and the device looks dead. Use a plain USB-A to USB-C cable with an ordinary 5V charger, into the power port rather than the data port. If it still does nothing, the stock microSD card is the next suspect.

Should I install ArkOS on my R36S?

ArkOS was archived by its developer, with its last update in August 2025, which almost every guide online has not caught up with. Its maintained successor is dArkOS, a Debian based rebuild by the same developer, still being updated in November 2026. There is a separate build for supported clones. Identify your board first, because flashing an image for the wrong board is the usual way people end up with a black screen.

What is the difference between the R36S, R36H and R36 Ultra?

All three use the same Rockchip chip, so they play the same games at the same speed. The R36S is vertical with a 3.5 inch 640x480 screen, the R36H is a horizontal grip shape, and the R36 Ultra is vertical with a 4 inch 720x720 square screen and adds Wi-Fi. Our full comparison is here.

Does the R36S have Wi-Fi?

Not on the base model, so no RetroAchievements, no netplay and no over the air updates. The R36 Ultra adds it. Some sellers list Wi-Fi on R36S pages regardless, which is one more reason to treat these listings as advertising rather than specification.

Do I have to use the card it comes with?

No, and you should not. The stock card is the most common failure point on the device and it is also where the preloaded game files live. Image a card you bought yourself, keep the original untouched in a drawer as a record of which board you received, and play games you own.
