Just Enough Linux Operating System (JELOS) is an immutable Linux distribution for handheld gaming devices developed by a small community of enthusiasts. Our goal is to produce an operating system that has the features and capabilities that we need, and to have fun as we develop it.

1 While not technically supported, JELOS is known to work well on a variety of generic x86_64 devices including gaming PCs, mini PCs, and laptop computers.
2 Anbernic RG353P/M/V/VS devices with both v1 and v2 displays are supported. RG353PS will not be supported.
3 To boot JELOS on Ayaneo devices, hold LC and volume up and press the power button, continue holding "LC" and volume up until the Ayaneo logo appears. Select the storage device with JELOS from the boot menu using the Ayaneo button, and then press volume up to boot the distribution.

Flashing
- Download the latest version of JELOS (.img.gz) for your device.
- Decompress the image.
- Write the image to an SDCARD using an imaging tool. Common imaging tools include Balena Etcher, Raspberry Pi Imager, and Win32 Disk Imager. If you're skilled with the command line, dd works fine too.
Installation
- JELOS is installed by restoring an image file and Flashing to a device's internal storage or an external sd card.
- On x86 devices JELOS includes an installation tool. The installation tool can be found in the tools menu, which is one of the systems listed within ES.
- JELOS operating system is stored on an Ext4 partition that can be read by LINUX but is not natively readable on Windows. Currently it is not possible to access the primary JELOS Ext4 partition on Windows to transfer roms.
- On devices that support a second sd card, the sd card can be formatted as Ext4, FAT32, or exFAT. JELOS will automatically detect the second SD card on boot and configure the relevant folders for storing roms.
Upgrading
- Download and install the update online via the System Settings menu.
- Download the latest version of JELOS (.tar) for your device.
- Copy the update to your device over the network to your device's update share.
- Reboot the device, and the update will begin automatically.
Network Access
- External services are disabled by default in stable builds. When enabled, the username for ssh and samba access is "root". The root password is generated during every boot, it can be found in the System Settings menu.

Credits
Like any Linux distribution, this project is not the work of one person. It is the work of many persons all over the world who have developed the open source bits without which this project could not exist. Special thanks to CoreELEC, LibreELEC, and to developers and contributors across the open source community.
