Rocknix G350 Fork
Along with the custom images they made for Lakka and Batocera, developer Paulyboi390 has released a custom fork of Rocknix specifically designed for the G350 handheld.
- Download the rocknix-g350.img.gz from the releases section of the project’s GitHub
- Using 7zip, WinRar, or your choice of archive software to unpack the downloaded rocknix-g350.img.gz archive and extract the .img within to a directory of your choice on your PC.

- Write the extracted ROCKNIX-BATLEXP-G350.img using Balena Etcher or the software of your choice (USB Image Writer pictured)

- After the write process is successfully completed, remove the SD card from your PC, and re-insert it into the G350.

- The OS will begin the unpacking and installation process automatically.

- After the installation process is complete, you should boot directly into the Rocknix OS. Don’t panic if the screen goes dark after the install page. It can take a good twenty seconds or so before the initial bootsplash appears.

- Once you’re into Rocknix, you can shut the handheld down, eject the card, and load up all your ROM and BIOS files into the STORAGE partition of the SD card.

ARKos or PAN4ELEC?
I’m a big fan of what’s happening with Pan4Elec on this device!
I installed ark OS and the right thumb stick mapping is wrong. Up is right, down is left, left is up, right is down
Any info on how to fix the right joystick issue? It seems that when ArkOS is installed the stick configuration is rotated 90 degrees anticlockwise. So left is up, up is right etc. I tried a few fixes that I found here and there but none fixed the issue so I had to go back to the StockOS ( even though I liked ArkOS more )
Go to https://github.com/retrogamecorps/G350-ArkOS-dtb and download Image and replace the in the boot volume
I wish I would’ve seen this before I played and created save states. I lost my save state in my favorite game and now I can’t save any game (it freezes and gets stuck at saving 0%). Is there a fix like a cache refresh in the original software or is it cooked because of the SD card? If so is it still salvageable to transfer to Arkos and keep all the games it came with?
I played my game when I got not knowing I had to do anything else to it now I turned it on and it says no SD card. What should I do I
My menu hotkey is not detected in retroarch can anyone please help me with this
Hi Paylyboy390,
I’ve had the same problem. Did you find a solution for this?
Yes a proper dtb swap is needed you have to rename the batlexp dtb to rk3326-rg351mp-linux.dtb
You can find Batocera and rocknix for the g350 at my github
