GammaOS Next v1.2.2 for the Anbernic RG DS in now here!
Hey everyone!!! 😄🎮
GammaOS Next v1.2.2 is now officially available for the Anbernic RG DS and this release is a proper quality jump for anyone using the device as an actual “DS-first” handheld.
I’ve wanted the RG DS experience to feel less like “two screens running Android” and more like a real dual-screen console you can actually live in, and I think we’re finally landing there. 🙌
📥 GitHub release (v1.2.2)
https://github.com/TheGammaSqueeze/GammaOSNext/releases/tag/v1.2.2-ANBERNICRGDS
🔐 Password (Full + Lite builds)

⚡ Lite vs Full (quick and honest take)
Both are included in the download, but I’m going to be straight with you:
✅ Lite is strongly recommended on RG DS
It runs smoother, stays snappier, and feels more “console-like” overall.
⚠️ Full includes Google Services
It works, but it slows this device down enough that it takes the fun out of it for most people.
If you want the best “pick up and play” experience, go Lite.
🧠 What’s improved in v1.2.2 (RG DS)
This update is all about making the RG DS behave like the device it’s meant to be.
✅ Fixed the 40 Hz bug on the top screen
Both screens now behave properly and match the refresh characteristics you’d expect from a real Nintendo DS style experience. No more weird mismatch vibes.
✅ DualStack support is here
This is a big one. You can make apps behave like a single-screen experience when you want, instead of fighting layouts that were never designed for dual displays.
Long-press the DualStack Quick Settings tile to tweak the settings. 🧩
✅ Fixed Drastic secondary screen latency (DualStack)
Touch and secondary screen response feels noticeably tighter now, especially when you’re running DS-heavy titles.
✅ Performance enhancements for Drastic
Less overhead, smoother frame pacing, and better responsiveness in actual gameplay.
✅ Touch panels now run at 120 Hz ✨
This makes touch motion feel way smoother and more “premium”, and it genuinely helps with DS gameplay where you’re dragging, tapping, or doing quick stylus-style input.
✅ Big quality-of-life upgrades for dual-screen living
RetroArch launching on the second screen (so you can keep your flow)
True multitasking without the system constantly pausing apps like it’s scared of background activity
Use the Launch Guard and Secondary Screen Quick Settings tiles to adjust behavior on the fly
✅ Fixed sleep issues 😴
Resume reliability has been improved so you’re not rolling the dice after standby.
✅ Fixed Widevine / Netflix DRM 📺
Streaming behavior is now corrected where supported by the device stack.
✅ Per-screen volume adjustments 🔊
Finally, the dual-screen audio experience makes sense.
✅ GammaEQ support 🎧
Better audio quality and more consistent tuning support across usage.
✅ Keyboard is now pinned to the *bottom screen*
Stop letting things get in the way of the top screen !

🙏 Thank you
Seriously, thank you for supporting GammaOS. The RG DS is such a cool device concept, but it needs the right software polish to really shine, and your support is what lets me keep pushing these niche devices further than they ever should realistically go. 😅🔥
If you try v1.2.2, let me know:

Hi Gamma I have tried using the password provided but it tells me it is wrong for the lite build is this a known issue. thanks
will there be 1.3 for RG477M?
I bought an RGDS on Facebook marketplace. Everything works fine just when I connect to Wi-Fi on one network. It won’t let me connect to a different network. It’ll even crash the system settings and make me reboot it but even then it would just go through a cycle until I completely erase everything and and restart it. Has anyone had this issue? I will say it already had the OS on the device and this is the first I’m hearing about a password.
I keep getting "wrong password" when i try to extract. Anyone else having this issue?
I'm trying to extract the one for the TrimUI Smart Pro, and I am getting the same error.
Are there any planned updates for this release?
I've set up gamma on my rg ds but there's a problem with putting the ds on sleep when closing. Whenever I close the ds, whatever app i use just resets and I've lost progress on games like that. Is there someway to get around this?
Cannot extract the 3 files. Corrupted :(
How do I revert to stock OS? Seems I cannot do anything but boot from SDCard now.
Anyone any idea why the download is taking such an age from Github? So slow
use IDM to download.
Great performance! The touch response feels like butter with the new polling rate. I'm just trying to get used to the dual-screen management. Sometimes I open the launcher on both screens and it drives me crazy! hahah
After a month of redoing my device several times due to corruption, I'm kinda done. If you need to store any apps on your SD card, this build will corrupt your SD card within a few days. Yes, there's a note about it when you're formatting the device, but it isn't mentioned before paying to download. I genuinely wish I just waited until it was made available for free because since the RG DS only has 32GB of internal storage, external storage is necessary especially after scraping all your ROMs with the included launcher. It's a shame because this runs really well when it's not locked up. I've tried both builds out for a couple of weeks each and really enjoyed them. The lite build gives you enough performance to play GameCube rather well with an optimized version of Dolphin, while the full version is nice if you want to make full use of Android without running into some apps and features that need Google Play services. Watching YouTube TV while playing Super Mario Run or GTA San Andreas on the other screen is the kind of multitasking that makes this device feel like a more modern DS and GammaOS can do it really well unless you run into one of these external storage issues down the road like I have. Unfortunately, it's something that doesn't appear to happen with just one micro SD card either. I've got several spares of varying brands and capacities and even my Samsung, SanDisk and TeamGroup cards all had the same issue after a while. Thank you for the effort. Please fix storing apps on external storage, it'll make this build more than worth the money you're asking if you do.
I still can connect to other wifi's after chaing the hostname but sometimes the wifi turns off and can not find any networks anymore. Only solution is a reboot.
It's great, but setting any kind of screen lock is completely broken on the RG DS and renaming the device breaks wifi in a way so it refuses to connect to anything but an already saved network.
Is there a way to play solely on the top screen while the one below is turned off ? I can only work with the bottom one while the top one is turned off. (on retroarch or psp emulation)
I'm sure you can't (at least not currently). "Officially", the console threats the top screen as the secondary. The system can only shutdown the secondary screen...
This unbricked my RGDS when the Anbernic build didn't. This is great!
Hey guys is anyone having issues opening settings or the dropdown menu I installed the lite version and I can only open games and apps can’t close them open or open settings
it's like Android. Did you hover your finger from bottom to top to show up the navigation buttons? There you can touch the square to open the multitasking and close what you want.
Love the Gamma Shader that applies a universal LCD pixel shader that just makes it feel like a big ole fancy DS. If we had some Shader settings to tweak it a bit to our taste, it would be the cherry on top of this feature.
Hey i cant install gamma os in my rg-ds, i have android 14 and im trying to flash my sd card with gamma os and i cant deal with it, can someone help me?
it starts the anbernic software and ignore my sd card
Great work. I stopped using the RGDS because it slowed down too much playing Solatorobo (a DS title). Hope this makes it worth playing again.
Thank you for your dedication. This is how Anbernic should officially prepare their OS's. Absolutely brilliant work!
Hey, I'm having big problems on putting gamma os on my RG DS stock fresh out of the box, I helped my brother set it up smoothly, first try, but mine just came and did the same thing, but when I boot up, it doesn't flash the console and set up gamma, but boots stock os and normal screen, I'm stuck and I'm worried about what to do next...
did you figure this out?
Thank you! When a game close from retroarch, dosent go the the bottom screen automaticly, you have to touch the screen, it stays on top screen. Can you make that, after the game closes, the main screen to go on bottom ?? EDIT: I had to use Tasker to resolve this, also beacon is much better than daijisho.
Hey all! So GammaOS Next has made DS stuff look and perform quite a bit better than stock - touch feels more responsive too. However, battery drain, sleep/wake, and charging all feel buggier than stock. It's actually gotten kind of annoying that I have to fiddle with the device in some way every time I open it up (having to wait for it to respond or pressing the power button multiple times to get it to wake), and the battery seems to get down to ike 20% overnight after a full charge, and stock wasn't nearly that bad for me. Hopefully, a future update can help with some of these issues.
Yeah I've noticed the battery drain as well, but it's probably gonna get some optimization
Hi everyone! I've tried both Console launcher and Beacon launcher. I prefer to use the console launcher, but as of now, I don't think the RGDS can handle it. Beacon launcher, on the other hand, works great, scrapes box art, and launches DS games correctly. Beacon launcher is pretty lightweight, so don't expect too many options in terms of customization. Since I don't have Google Play, I had to download the APKs.
Does anyone else have issue with after shutting down or going to sleep, RG DS does not wake up anymore? Not even charging light lits when charging. Somehow, taking off the battery and pushing volyme down + power key i managed to resurrect my console. But same thing happened again.. Must i keep console powered on all the time to prevent this from happening?
I haven't had it completely lock up on me, but I do find things are a little inconsistent with waking and charging the device. Not sure if it's the deep sleep feature causing these bugs or not
When this thing occasionally gets stuck mirroring the top and bottom homescreen together how are you guys fixing it?
In this case, I hold the power button and select "Kill all apps". It's been a good way to refresh
Hey guys, have anyone noticed a battery drain issues? I've seen that if I put it on sleep mode, the baterry goes down a lot, why is that? Should I just turn it off for the night if I'll not use it?
It’s normal to drain 30% a day while in sleep I think
Hello, I made a bootable SD Card (512gb) via Rufus and the GammaOS Lite version, but the RG DS will not flash, it just starts up to its original OS. Any ideas on this?
I have the same issue, I don't know what to do, did everything as intended, but only boots up stock os
wifi picks and chooses when it wants to work. this has been a thing on stock and gamma. ive seen others posting similar wifi issues, some resolve by clicking the reset in the wifi options. for me if it doesnt return network results it wont work. I have to reboot several times and get lucky
Sometimes when I close a ds game the both screens show the launcher and only the upper screen respond to touch. Didn't find any way to fix it, only by restarting the device
Having the same issue. Made a comment below. I haven’t seen others mention it and I don’t know how to fix it.
Thanks for your hard work
Thank you for your effort. Dementium II is not working.
Hey Gamma, I'm trying to remap the Anbernic button on the RG DS. Where can I go for that? I've tried under the buttons settings, but it's still bringing up the notification panel
For those who are having issues with the device not booting, after a fresh install or after a crash, try unplugging the battery and plugging it back in.
I tried that, but it still just comes back to an orange Anbernic logo. I'm out of ideas (and kind of sad lol)
I've got the same problem a couple of other people have mentioned. It rebooted to an orange Anbernic logo and sticks there. I can't reflash Gamma or the original firmware. Think I'm bricked.
I try to open the firmware but the sd tool always fail to open the file after i click create
When there's an update for this will it auto update? Or where do I get that update, thanks
You out here doing God's Work appreciate you boss!
Thanks gamma. This is some great stuff you did here, anbernic should really just contract you at this point. Would it be possible to add in the feature to use 2 different wallpapers though? And potentially a button to bring up the software keyboard on the navigation bar?
Thank you gamma! Dual stack in artemis streaming app has been an excellent way to play 3ds on this device and be able to upscale it a bit too.
This appears to have bricked my device. The install was successful and I played briefly, then told the device to restart. It is now completely unresponsive. Update: Disconnecting and reconnecting the battery revived it. Looks like the same issue that happens between Rocknix and GammaOS, but I never used Rocknix, so I'm not sure what caused it.
Thank you for having not forgotten about us Anbernic RG Da guys
It's a nice and clean OS now but I don't know about the performance. Played around with it and have two of them. Even though Dualstack does a better job at combining bot screens it does not make a whole lot of difference for the games I play. Most games perform the same as stock. Great job all the less but for now I stick to Linux Rocknix which has bigger performance gains for my daily usage. Keep up the good work.
Thank you very much for GammaOS on RGDS @Gamma I have a question though. Is there away to have GammaOS prevent android from creating a default folder structure on the sdcard? Its a small annoyance I have with android in general. Every card you put in android creates the default folders: .$Trash$/ .android_secure/ Alarms/ Android/ Audiobooks/ DCIM/ Documents/ Download/ LOST.DIR/ Movies/ Music/ Notifications/ Pictures/ Podcasts/ Recordings/ Ringtones/
Worked a treat. I used Mint Linux and Pi imager to burn image, Windows 11 just kept giving image writing errors. So good to be able to use the RG DS to it full potential. Thanks
I have noticed when using dual stack with drastic. If I put the console to sleep then wake it up and quit the game through the drastic menu Daijisho launches on both screens and won’t respond to touch and I have to reboot the device to get things to work properly again.
No gamma OS core release planned for the console?
I cannot get it to boot I tried multiple times to flash the Img to sd card it is a high quality sd card and I tried with raspberry pi imager and balena etcher and multiple times tried to install on device and gets stuck on orange ambernic screen every time and I did lite version and waited hours like 4 on one attempt and still did not move past on any attempts Dug Further and 7zip is saying Data error : Wrong password? : RG_DS_GammaOS_Lite_v1.2.2_SDCARDINSTALL.img I made sure it was copied correctly and does not work
Can I change the launcher?
its android, so you presumably you could install a new launcher, then go to the default apps section and set that launcher as your default.
Man you are a savior for this device ! I was so disappointed with the stock os that i almost decided to sell it , I've been waiting for this release & the performance is on next level for DS titles.And not just performance the overall experience of using this device is improved, now it really feels like a handheld console & less like a cheap android that it used to be. Thanks for your hard work & support for this device !
Good Afternoon is there a hotkey guide for this OS like to activate max performance, I installed the lite version but seems to be getting stuck at every other app
That would be great, after a day I am still figuring out the volume/brightness controls.. :D
Done! Updated to be flashed via SD card now, for ease of installation: https://github.com/TheGammaSqueeze/GammaOSNext/wiki/GammaOS-Next-Installation#step-a-prepare-the-sd-card-image
Hey guys!! I’m getting stuck during the flashing process. [info] converting existing fastboot to fastbootd
Just had to manually reboot the device and it started flashing! So excited for this, thank you Gamma!!
I am working on SD card images for flashing instead of using Fastboot. Should resolve flashing errors. Will be able to create the update card using dd/balena/rufus etc. Will be uploaded today
Done! Updated to be flashed via SD card now, for ease of installation: https://github.com/TheGammaSqueeze/GammaOSNext/wiki/GammaOS-Next-Installation#step-a-prepare-the-sd-card-image
ive done the process twice, and when the system boots, it looks like the device is killing the homescreen and restarting it, resulting in the lower screen turning off then on again. Using the lite image. external sd card is not installed when this happened.
not sure why, but i initially did this on rhel. doing this on a windows device, i now have orange anbernic logos on boot and the problem has seemed to dissapear. probably a permissions issue when flashing on linux.
As in another really cool handheld SAVED
Another one
Is there a hotkey or button to swap screens like stock had?
Do you have an unbricker for RG DS?
to those using the lite version, are you having issues with your wifi not working? this happened on stock os as well but was fixed in the update 1.15
Yes! Installing this right away! Been playing Hotel Dusk recently
Not a super techy guy, but I did a clean install and followed every instruction to the letter. GammaOS Next Lite is now on my RG DS with no problems during install. However, it's running 70% of the CPU at rest and 95%+ when playing GBA games. What's a good way to get that down?
Hello - When I try to load a 3ds game in both .3ds and .cci format, the top screen seems to load for a bit and then goes black while the 2nd screen remains in the library section. Any help is appreciated, thanks
Running into an issue when running the flashpartitions.bat , Connected ADB devices: Connected Fastboot devices: [Info] No ADB or Fastboot device detected yet. [Info] Check that your RG DS is connected, powered on, and that drivers are installed. [Info] Checking again in 5 seconds... I am able to detect the device using the Open CMD.bat in the ADB and Fastboot++ file folder. I am also able to boot into fastbootd on the device. Any ideas?
go to : https://github.com/K3V1991/ADB-and-FastbootPlusPlus/releases then install the msi version and do NOT use the portable version, it looks for the exe found out the hard way and now mine is flashing!
Idk why I'm having bad input latency on the lite version, when using both retroarch and drastic, am I doing something wrong?
got it up and running on full with my existing SD card, this is flipping good man, well done!
Having issues entering a pin on the full install, seems to freeze and screen stops responding
Not recommended to use the Full install
quick tip for anyone who gets the multiple devices error when running adb run: adb devices find the one that is not emulator, copy the device id run the adb command with: adb -s ...
Gamma is the GOAT!!!🐐
Dude, I was so disappointed by the Anbernic firmware. I didn't think anybody would bother fixing it. You kick so much ass. Thanks.
Thank you so much. Install done, now setting it up on the device. Been waiting so impatiently for this. You're the man!
Thanks Gamma, again a master piece. 🥰 love it
Can you do a Gamma OS for OneSugarOne X dual screen device? Thanks!
+1 that would be amazing if that would be possible
Have you tried to figure out how to turn off the bottom screen? Would make the experience a lot better for other systems
Not off completely but you can use split brightness mode and turn the bottom screen brightness down
Much appreciated Good sir! Appreciate all of your efforts 😎
You're a saint! Things been collecting dust since Christmas day. Thank you!!
This will make DS cores on RetroArch playable, would it?
No
Love this Gamma. Amazing work Qq... For Lite version, if folks want Play Store type access do you recommend using the FDroid and then Aurora similar to other Lineage OS builds?
Yes
Does lite at least do signature spoofing for MicroG like vanilla LineageOS does?
Same question 👍
