Gadget Guides – JELOS Beginner’s Guide for Anbernic RG353 Devices

Written by thegaminggeek

November 19, 2022

The RG353 series of retrohandheld devices from Anbernic has become very popular recently. One of the reasons why these devices have become excellent gaming devices is because of JELOS, a community developed Linux-based operating system. This guide aims to help new users with some frequently used features of JELOS.

Please note that this guide is specifically for devices in the RG353 range – the Anbernic RG353P, the Anbernic RG353V, the Anbernic RG353VS, and the Anbernic RG353M. While JELOS is also available for other handheld devices such as the Anbernic RG552, the tips in this guide may not be applicable to those.

Note: The JELOS team has discontinued support for Anbernic devices. In its place is UnofficialOS, which are JELOS builds done voluntarily by a member of the retrohandheld community, RetroGFX. I’ve updated the guide to add the link to where you can download the UnofficialOS releases.

To turn your RG353 device off:

  1. Exit the software/game/app you are currently using (instructions below).
  2. Press Start in the JELOS environment to bring up the Main Menu.
  3. Choose Quit (near the bottom) and Press A.
  4. Select Shutdown System and Press A.
  5. Choose Yes and Press A on the following prompt.
  6. Wait for the device to turn off.



In case of firmware failure and you don’t have a backup, here’s how you can quickly get your device up and running again. These instructions are specific to Windows.

  1. Download Win32 Disk Imager. You’ll need this app to install the firmware.
  2. Download/install 7zip to extract the image from the 7z format.
  3. Download the latest version of JELOS here.
    • The latest releases of UnofficialOS (uOS) can be downloaded from this repository.
  4. Insert the TF1/Int microSD card that came with your device into your laptop/PC. You may need an SD card reader for this.
  5. Using Win32 Disk Imager, flash the firmware image to the microSD card. This can take 10-15 minutes.
  6. Once you’re done, you may get several errors saying that the disk needs to be reformatted. Close them and eject the microSD card.
  7. Insert the microSD card into your device and power it on. Wait for JELOS/uOS will complete the installation process.
  8. Device is ready once the Emulationstation menu is displayed.

Sometimes, specific games perform better using specific emulators/cores. In some cases, they might not even run properly. It’s a good idea to try changing emulators/cores when having trouble with specific games.

  • In the game selection screen of the system you want to change emulators for, press Select.
  • Choose Advanced System Options (at the very bottom of the list).
  • The top option will be Emulator, which is set to Default by default. Press A to see the list of available emulators for that specific game system.
    • Note: Cores running through Retroarch will have the prefix “Retroarch:”. Emulators/cores without this prefix are likely standalone emulators, which will run outside of Retroarch.




Some disc-based systems will have multi-disc games. When playing these games, they may prompt you to insert the next disc. Here are the instructions on how to do this.

Default Playstation 1 Emulator

  1. Press Select + X to bring up the Retroarch menu.
  2. Scroll down and choose Disc Control.
  3. Choose Load New Disc.
  4. Choose the next disc of the game that you’re playing in the list of files that appears.
  5. Proceed with the game.


Sega Saturn (Yaba Sanshiro)

  1. Press Select.
  2. Choose Open CD Tray. It will change to Close CD Tray. Choose it again.
  3. A list of files will appear. Choose the next disc of the game that you’re playing.
  4. Proceed with the game.


Default Sega Dreamcast Emulator

  1. Press Select + X to bring up the Retroarch menu.
  2. Scroll down and choose Disc Control.
  3. Choose Load New Disc.

    Tip: Don’t mess with JELOS on Anbernic devices!

    I’ve got it running on my RG353M and I love it, but the JELOS dev team stopped supporting non-x86 systems in December 2022. No more updates. If you have the fortitude to build the OS from source, it’s still possible, apparently, but I wouldn’t bother.

    • thegaminggeek

      Well, this was written weeks before they announced that they’ll stop the builds and more than a month before they dropped support for Anbernic completely. But the 20221130 build is still up on their github page, and it still works well except that you can’t install Drastic on new flashes any more. That version is still good for the RG353 devices.

    Rg353vs arkos, when I insert a samsung 64gb sd card formatted exfat, and select to use slot 2 for roms, I get this error Could not find a Fat, Fat32, Exfat, EXT4, or NTFS based sdcard to mount from slot2

    • thegaminggeek

      Do you have other sd cards you can try? I’ve had an RG353VS with a busted slot2 – it wouldn’t read any microsd card I use (and I’ve tried a lot).
