Change Log

New Features

  • Adds support for changing the merged storage target between the internal and external card.
    • Since JELOS creates the games directory structure it is possible that the overlay will hide games if you switch targets as it will consider them removed. Delete the empty directories and reboot to resolve.
      • Ex: find /storage/games-internal -type d -empty -delete && find /storage/games-external -type d -empty -delete && reboot
    • Merged storage can now be disabled persistently.
    • A new directory structure is required to enable switching:
      • /storage/games-internal/roms
      • /storage/games-external/roms
      • The target /storage/roms has not changed.
      • Games will be migrated automatically when possible.
      • If game directories are not created correctly, ssh into the device and run systemd-tmpfiles --create /usr/config/system-dirs.conf.
  • Lowers RK3566 device clocks when put to sleep.
  • Adds ATSC acceleration and CPU accuracy options to Yuzu.
  • Adds TWB64 - Pack 3, thanks to @GlaZedBelmont!


  • Update Mali Bifrost and Vulkan to r46 (S922X).
  • JELOS now uses Xwayland and has deprecated xorg-server.
  • Updates Portmaster, Citra-SA, Flycast-SA, Yuzu-SA, Cemu-SA, Gambatte-LR, and the Linux kernel to 6.1.65 and 6.6.5 on supported devices.
  • Check if the controller is registered and 8bitdo and force 360-behavior in mednafen, thanks to @sydarn!

Bug Fixes

  • Fixes an issue with Yuzu graphics glitching due to bad Mesa compiler flags.
  • Removes 1908 clock as it is not present in the BSP kernel (S922X).
  • Corrects an issue with Yuzu prompting for confirmation when closing the app.
  • Update process now removes stale profile scripts that cause missing audio on some devices.
  • Fixes a udevil regression preventing thumb drives from mounting automatically.
  • Corrects factory reset to ignore new games paths.
  • Applies a workaround to portmaster to set permissions on games if they are not already set.
  • Adjusts available clock frequencies on RK3326 devices to improve stability.
