Updating KNULLI

OTA Updates

Batocera supports OTA (over-the-air) updates which can be executed directly from the EmulationStation GUI. Consequently, KNULLI also shows the OTA update menu. However, currently, we do not have OTA servers set up, yet. Until we do, we kindly ask you to update your KNULLI installation manually.

Manual Update

KNULLI can be updated by downloading the boot package for your device and replacing the batocera file manually.

  1. Download the latest boot package for your device from our Releases page by following these steps:
    • Scroll to the bottom of the latest release to find it's Assets list.
    • Identify the boot package for your respective device by making sure
      • it contains the device name (e.g., rg35xx-h for the Anbernic RG35XX-H).
      • it ends with boot.gz, boot.xz,boot.tar.gz, or boot.tar.xz.
      • it has a size of approx. 1.5-2.0 GB.
    • If you have any questions you can check the Device Support section to confirm which image you should download for your specific device.
  2. Extract the data from the compressed file (e.g. with 7-Zip).
    • Be aware that a package that ends in tar.gz or tar.xz contains a compressed file within a compressed file, so you might need to first take the tar file out of the gz/xz file before you can extract the contents of the tar file.
  3. Insert your KNULLI SD card into the SD card reader of your computer.
  4. Replace the file boot/batocera on the BATOCERA partition of your SD card with the file boot/batocera.update from the file you downloaded by following these steps:
    • Delete the existing batocera file or rename the current batocera file (e.g. to batocera.bak) if you want to keep it, e.g., to be able to downgrade to the previous KNULLI version again. (If you still have a backup of a previous KNULLI version, you might want to delete this now to make some room.)
    • Copy batocera.update you extracted from the boot package to the boot folder on the batocera drive of your SD card.
    • Rename batocera.update to batocera.
  5. Reboot the device, and the update will begin automatically.

Re-creating default settings

Usually, KNULLI updates will NOT require you to re-create neither a single configuration file nor your entire system folder. However, in VERY rare cases it might be required to adapt your configuration to new KNULLI default settings. In those cases, the easiest way is to reset to factory settings, either by re-creating single files or sometimes the entire system folder. You can learn more about it in the Reset to factory settings section, however, do NOT do this, unless you are absolutely sure it is required!
