The RG350 is out in the wild! I’ve had my unit for a couple of weeks now and it’s time to share some thoughts on the device. Is it all it’s cracked up to be?
2018 and early 2019 saw a tonne of handhelds released with almost identical hardware, the JZ4760/B powering the vast majority of them. A ten year old processor that offers reasonable emulation performance for most consoles up to and including the Super Nintendo. It’d be easy to forget that in 2013 we already had a natural progression from this processor when the GCW Zero was released. The GCW Zero’s JZ4770 CPU offered superior SNES emulation and allowed for a wide selection of PS1 games to be played at full or close to full speed. The GCW Zero became mostly unavailable to buy a few years later, and we saw shift towards ARM powered Android handhelds filling the void for the next couple of years.
With the release of the RG350 we’re seeing a renaissance of the JZ4770. Whilst the RG350 is a real progression from the recent LDK, RG300, RS97 and even PocketGo it must be remembered that this machine is still running a middle-of-the-road MIPS processor from 2011. As such, if you’re expecting a console capable of N64, Dreamcast, GameCube or PS2 emulation then Android handhelds are still your goto devices. On the other hand if you’re into older consoles and Linux is your thing then the RG350 might be exactly what you want.
The RG350 is a collaboration between the manufacturers of the RS-97 and Tony Jih, a Chinese software and hardware developer that has voluntarily worked on firmware for many of the previous handhelds in 2018 and 2019. Without further ado, let’s take a look at the machine and see what it’s all about.
The RG350 is currently available in three colours. I opted for the smokey transparent grey as I’m a fan transparent shells.
Aside from the bump in performance compared to its rivals, the RG350 promises a few other nice additions which help set it apart from the competition. As well as the d-pad, the RG350 boasts two real analogue sticks. These are very different to the nubs found on the RS-97 Anniversary Edition and the GCW Zero as they offer full 3D movement rather than sliding laterally over a flat surface.
The unit features 4 shoulder buttons, 2 sets of USB-C ports, a HDMI output, a reset button, headphone output, volume rocker, and an external microSD slot. The RG350 also has a pair of stereo speakers and rumble motors, which is unusual for a device such as this and a welcome addition.
Build Quality and Controls
At this point many of these handhelds rival products from mainstream console manufacturers in terms of build quality. Despite its other flaws, the PocketGo is one which I’m sure could not be improved upon in terms of fit and finish and I’m happy to say that the RG350 is another. That’s not to say that the controls are perfect (we’ll get to that) but as far the manufacture and assembly of the RG350 goes there is little to find fault with. The unit feels premium in almost all aspects, with some notable mentions going to the beautifully executed shoulder buttons and analogue sticks.

Notice how far out of the shell the d-pad and buttons sit.
The device comes equipped with enough buttons to service every console it’s capable of emulating and the additions of a volume rocker (instead of a wheel) and accessible reset button are welcome ones.
I have two gripes with the controls – the first one obviously being the placement of the d-pad. We all knew that this might be an issue, and for me it unfortunately is. I have big hands and I would find the d-pad way more comfortable to use if its position was switched with the left analogue stick. I find myself having to have a very loose grip on the left side of the console with my thumb fully extended in order to use the d-pad without getting cramp. It’s not a deal breaker, but it’s unfortunate.
Secondly, I find the ABXY and d-pad protrude slightly too far out of the case. Although the RG350 has the exact same d-pad as the RG300, the RG350 d-pad protrudes from the shell around an extra millimetre. It’s not much, but it means that sliding your thumb over it is not as fluid as it could be. The same can be said for the ABXY buttons, they’re too tall and could do with being recessed by 1 or 2 millimetres in my opinion.
The analogue sticks are the best we’ve ever seen on a device like this. They’re similar to the ones found on the GPD G5A but smaller. They have a textured rubberised finish on top and a small lip around the very edge to provide extra grip. They also function as L3/R3 when pushed down and in my opinion they are perfect. The OS comes with a homebrew app to test the function of all buttons on the device and the analogue sticks are registering exactly as I would expect.
The shoulder buttons are also very well put together with L1/R1 curving around the edge of the shell and L2/R2 set just next to them on the inside. They register with a very soft click and are easily reachable whether you’re using the d-pad or the analogue sticks.
LCD
The RG350 houses a 4:3 320×240 IPS display at 3.5″ in size. The colours and the viewing angles are excellent in every orientation, only beginning to fade and invert when viewed from extreme diagonal angles. It’s a shame that the panel isn’t higher resolution, the pixels are easy to see on a screen this size and consoles such as GBA really suffer with the non-integer scaling required to display games using all of the screen’s horizontal real estate.
I understand that it’s difficult to accommodate all consoles when choosing an LCD but it would have been amazing to see a super high resolution panel such as the one used in the upcoming Analogue Pocket, where sheer pixel density would overcome many of the scaling issues. But this adds extra cost, and the console is already pushing the boundaries of affordability for many so I do understand their choice. The LCD operates at 60hz and looks beautiful, with vivid, vibrant colours and no screen tearing to speak of.
Whilst there’s no app or dedicated button for screen brightness, it can be adjusted using the Power + Vol button combination.
Firmware, Emulation and Battery Life
As of writing the current firmware is RG-350_BASE_v1.4_121019. This is newer than the version that shipped with my unit, but mine was delivered a couple of weeks ago now. If you need the v1.4 firmware use the link above to download it. It is possible to apply patches to bring the firmware up to date instead of re-flashing from scratch. This can be done by dumping the patch in the /media/data/apps folder and running the OS Update application.
To transfer files to the RG350 you can either remove the external SD card and stick it in your PC, or you can access the unit via something like Filezilla or WinSCP. To do this you need to plug in your device using USB2, load the Network application and select the connection method you want to use. Then you can access the unit using the IP address and logon name given in the Network application.
Depending on how many updates you need to add it may be simpler to just flash the entire new OS image from scratch. This is what I did and it requires you to disassemble the device to get at the internal SD card. Instead of wiping my internal SD and flashing the new image, I decided to use a new SD card. This means that if I’d messed it up somehow, I could still use the other card with the original firmware on it whilst I figured out the problem. Thankfully everything went according to plan following the instructions here. In my opinion Anbernic should have made both MicroSD slots accessible from the outside, it would make the re-flashing process far easier and less time consuming.

The img file linked above comes with the latest version of all emulators included, however all apps and games are included in a separate zip file. You can choose which of these you want to include by following the instructions here.
The RG350 has a 2500mah battery installed, which is 300mah larger than the one found in the GCW Zero. Battery life is ridiculously good in this thing, I’ve played a mixture of PS1 and GBA for hours and hours at a time and the battery meter has barely dropped. I would estimate that the device has somewhere between 5 and 8 hours of battery life depending on what you’re doing with it. It really is exceptional.
The JZ4770 offers a notable increase in performance in SNES SuperFX/FX2 games. Games such as Star Fox and Yoshi’s Island still rely heavily on frameskip, however the difference between the JZ4760B and JZ4770 is very obvious. These games on the RG300 (JZ4760B) were unplayable, however on the RG350 they are enjoyable to play as long as you can live with frameskip.

Whilst frameskip is still necessary, for me Star Fox is playable now.
Playstation emulation is also good on the RG350. I have sunk a few hours into Diablo, Ridge Racer Type 4, Tony Hawks Pro Skater 2 and Gran Turismo. Diablo stutters a little until you’re in a dungeon and then frame drops are minimal. I’m sure there are plenty of PS1 games that are still unplayable, but the library of playable games is opened right up on the JZ4770 with everything I’ve tried so far running very well.

Version 1.4 of OpenDingux running on the RG350
You know the drill by now, this is an open source handheld running OpenDingux and as such development is ongoing all the time. Whilst a game might only reach x FPS today, tomorrow an emulator or OS tweak may bump the framerate by 5 or 10 FPS. Although a lot of the library is already fairly mature having been brought over from the GCW Zero versions, never under estimate the determination and skill of the developers!
Caveats and Bugs
Unfortunately not all of the advertised features are currently working. Although the rumble motors can be tested in the input test app, they’re not used in any emulators yet as far as I’m aware. I know that this is being worked on and will eventually be worked into the software. Likewise despite the HDMI port being present, the software is not currently in place to support it. It’s unfortunate that the machine was rushed out before these features were working, but then again it gives us all something to look forward to in the coming weeks or months 
Overall Thoughts and Summary
The RG350 is a step forward in many ways, but it also feels like treading water in others. Whilst it’s a shame to see no advancement in raw CPU power since 2013’s GCW Zero, it’s obvious right from the outset that the RG350 has been designed and built with far more thought and skill than the GCW or indeed most other current Chinese handhelds.
In my opinion the RG350 represents the best that we currently have coming out of China. It’s a solid effort all round with only a few drawbacks, of which some are personal preference. The design and execution is outstanding and it’s obvious that a lot of thought and attention to detail has been given to this device during research and development.
With that said, here’s my verdict in a plain and simple pros and cons list.
Pros
- Excellent build quality
- Vivid and colourful IPS panel
- Mature and stable operating system and emulators
- Amazing battery life
- Comprehensive and well thought out controls (for the most part)
- A genuine step up from the majority of 2018 and 2019 handhelds
- Ongoing development for the foreseeable future
Neutrals
- Higher resolution panel would have been nice
- Price is borderline too high for some
- D-pad and ABXY protrude too high from the shell for my taste
- Both SD cards should be accessible externally
Cons
- D-pad and left analogue positions should be swapped
- Rumble and HDMI not working as of October 2019
- In 2019 it would be nice to see more CPU power than this
The RG350 can be picked up from the official Anbernic store on Aliexpress in a choice of 3 colours, as well as from Amazon if you’re willing to pay a little more to have it faster.
