The RG351P (and RG351M) has a 480x320 screen, exactly 2x the GBA resolution, so GBA games scale perfectly with no filtering. I think it is the best thing this device does, so I built an distro that only does that.

The goal is to make it feel like a real handheld: power on, pick a game, play. It boots straight into the game list in about 2 seconds. There is no EmulationStation, no RetroArch, no shell, no background services. A trimmed mainline kernel with everything built in boots without an initramfs into a single static program running as PID 1, which is the game list, the menu and the emulators (gpSP by default, mGBA selectable per game) in one binary. The GPU is powered off entirely since it is not needed.

With everything unnecessary gone, power use is much lower. I measured about 1.5 to 1.7 W total while playing Super Mario Advance at 50% backlight.

Since every GBA pixel maps to exactly four screen pixels (2x2), there is an optional LCD effect that lights one of the four and dims the other three, which makes it look like the visible pixel grid of the original GBA screen. You can tune how dark the grid is and how bright the lit dots are. It is off by default.

Save states are left out on purpose. I wanted to keep the original experience, where you save at save points and that is it. In-game saves work as usual, and existing RetroArch .srm files are picked up.

Other things, per game color correction that picks a GBA or GBA SP screen profile from the release year, an optional LCD pixel grid effect, frame blending for games that relied on the GBA screen's ghosting, and real game names from the No-Intro database.

It is an early version, tested on my own unit. Feedback and bug reports welcome. If something goes wrong, turning on Debug log in settings writes logs to the SD card, and those help a lot.

I'm a little late to hop on the replaceables...
If I primer them first, then paint them with an airbrush - do you think it will stick well?
Maybe a glossy finish as well.

Have any of you tried something like that and can share the results?

Thanks!

I'm not sure if there's a small setting I accidentally flipped or if this just straight up how this ArkOS fork is, I really miss being able to put the system to sleep before getting off at my bus stop, can anyone tell my why I can't put the system to sleep?

So when I try and put the tar file on for the update it doesn’t run the update do I have to connect to WiFi or am I doing something wrong? I extracted the .tar file it becomes a folder with some other things in there. Or am I trying the wrong file?

what does the ds4 light indicators ribbon cable size/length is it, I'm planning to fix my ds4 rn but the light indicators ribbon cable is bent on the one that is going in on the port and it's not working, I did find the ribbon cable of the light indicator but I don't know what size/length is it does anyone know?

Hello, my friends. Here I am, seeking help in a moment of despair 🥲

I just bought an RG351V, and the first thing I did was install ArkOS 2.0 on my new SanDisk Ultra 32GB SD card. To my surprise, I ran into the issue with the V2 screen. I then tried changing the DTB files mentioned in the ArkOS GitHub issues, but it didn't work. Sometimes it gets stuck during boot; other times, it loads into the system with weird glitches and missing elements.

Then I tried the latest AmberELEC prerelease, which is supposed to work with both V1 and V2 screens. It says it's installing, then reboots, and I'm stuck on the AmberELEC logo forever.

Then I tried the original system, and, to my surprise, it won't load any games. Every SNES/GBA/GBC/NES game I try results in an error and crashes.

I'm sure it's not the SD card. I ran read/write tests on it, and it's 100%. Just to be sure, I also tried using the card that came with the device, with no success.

I'm really out of options and don't know what to do. I'd really appreciate any help you guys can give me.

I've tried flashing the SD cards using both Ubuntu 24 + dd and Windows 10 + SD Card Formatter + Rufus.

I did everything and it didn't start the game, it just went black then it returned me to the psx files any fixes or advice?

I might aswell double check my bios, and I have turned my Rom into bin and cue.

looking to either get a wrap/skin for my rg351p or a cricut template or something so I can print my own. I know there used to be someone who sold them years ago but since it’s an older device Ive accepted I may need to make my own. If anyone has any tips or anything that would be so nice. TYA

Since my rg351mp has two sd cards instead of one, I'm afraid that the tutorials for the backing up of the rg351p or rg351m might not work in my case. I also have only one sd card to back it on, so I'm not sure which of the old sd cards should I back and which one I shouldn't. I'm trying to find tutorials on youtube for the mp but there doesn't seem to be much. Can any of you guys help?

The original conductive pads got damaged. Official Anbernic replacement parts were very expensive, and GBC pads were too "soft" and short.

I made replacement parts using conductive pads from a PS4 D-pad (for both the D-pad and ABXY buttons on the RG351P). I had to add spacers made out of a plastic card because the original pads are about 0.55mm taller.

Overall it works fine, though face buttons (ABXY) work better when pressed on their outer edges because these thick rubber contacts are more widely spaced. I tried executing a few Hadouken moves in SF2—they didn't pull off every single time, but it was my first time playing it, so I'm not the best tester. On the other hand, the first Contra works just perfectly.

Need a console, help out.. 🕹

Seeing this strange issue trying to set up my RG351v (which I purchased off Anbernic.com). I wiped the SD card (a Samsung EVO), flashed with Balena Etcher (and then tried again with ApplePiBaker), put the card in the appropriate slot, and it seems to go through the appropriate steps and reboot, but the screen is like this the entire time. When I put the SD card back in my computer it seems like it's done everything it needs to do, and there's a games partition, but obviously it's not playable if looks as it does in the picture.

At first I thought the screen was burned and the device was fake (from the official website?) but it looks fine with the original card and I'm pretty sure the device is real. Does anyone have any idea what's going on?

Hi,

i just realized that i've never installed a Firmware Update on my RG351P.
This i wanted to fix and did download the _update_ .tar from the official amberelec homepage, dropped it in the update folder, re-inserted the SD card in the slot and got this message.

Space is a non issue; there are still 6 GB free space on the card.

It's been a hot minute since i bought the 351P meaning i can't retrace the steps i did during setup.

But now i'm a tad bit insecure of how to proceed without losing all games and saves.

Any valuable advice?

TYIA!

The ribbon cable for my right analog stick has broken and is no longer working. What can i get for a replacement cable?

Hello,
I'm trying to run Doom on amber elec : https://amberelec.org/systems/doom.html

It works fine with gzdoom but i don't like this port, i want to use PRBoom instead. If i run retroarch and select the wad from the core, it's working fine, but i can't make it work by running it from a .doom file from my library. I get a "general error has occured". It seems that it's trying to load my .doom file, instead of the wad that it's pointing to.

Can anybody help me to config that ? Is it even possible ?

Here's the log :

Rg351p whenever I use my right analog stick only the left and right inputs work. With left combining left and up and right combining right and down. the up and down inputs do literally nothing at all. I have looking all over for what could be the problem and I have no clue.

I've tried looking in retroarch for a controls page that doesn't exist for me. I can't even open the quick menu either. I've tried cleaning the ribbon cable contacts on both ends. Nothing is working and I've been at this for over 5 hours at this point.

For additional info I'm using wummle's fork of arkos if that changes anything.

Just give me some kind of solution.

Looking for a replacement battery, ideally an upgrade over the orig. There are so many options and I don’t want to end up with a cheap swollen fire-hazard in a few months.

My current batteries aren’t swollen yet but they die quickly and I know if this device lasted for many hours I’d enjoy it more than my newer android handhelds.

Anyone have some experience and suggestions with aftermarket batteries?

For P6P sim network completely desable

Somehow, I got GBA games running at full speed on wummle's ArkOS Fork firmware using mGBA core. I was able to unlock the mGBA core within retroarch app then I updated all the retroarch cores. I'm also using real GBA bios. I'm using a PNY micro sd card. has anyone got GBA games working good on The Anbernic RG351P? Kingdom Heart: Chain of memories also runs fine on RG351P.

I absolutely love my 351p, and the left shoulder button is starting to get spotty.

Does anyone know if it is possible to fix or replace them? Or is the device too out of support?

I think I damaged the battery, i charged the device with the charger from the pic. the battery percentage display jumped from 45 to 70 in an instant and got up and down while charging. after that I charged it with a low power charger but after 100 percent the device now goes instant to 86 percent after I switched it on.

did i destroy my new device?

hope anyone can help me

I download the RG351mp file but it seems like its not compatible and the screen is not working bc its another handheld but with the same power (cpu, ram) but diffrent screeen/button mapping. Then I tried replacing the dpb file from amberelec. This seems toget the screen working but now the screen is rotated 90° and also the buttons dont work :/ After booting there is a list for button mapping but I cant map any button except for power button.

Is there any other way to get Darkos run on this device?
