Notes:

  • By default JELOS will detect your controller and configure RetroArch hotkeys automatically. This is controlled by the "AUTOCONFIGURE RETROARCH HOTKEYS" option in the Settings > Controller & Bluetooth menu. While the option is enabled, RetroArch hotkeys will be overwritten by the above defaults each time RetroArch is launched. If this behavior is not desired that option can be disabled and your user-defined RetroArch hotkeys will be used instead.

HDMI Output

These instruction only work for aarm64 devices. This is not implemented for x86_64 devices.

Press L1 + START + SELECT while in EmulationStation to swtich between Screen and HDMI output.

While this should work; it doesn't always result in the correct resolution. The best way to get consistent results is to turn off the device, plug in an HDMI cable and reboot.

"Why doesn't hot-plugging just work?"... Hot-plug HDMI switching is a fairly complex action to accomplish and not something we have implemented on any device. If you are a developer and interested in helping to build this functionality please start here: Contribute

Booting from an SD Card

In order to launch JELOS from an SD card or a USB drive you will need to first change the boot order in the BIOS.

During boot you can enter the bios by either (1) holding the Home+LCC (Turbo) buttons that sit bellow the dpad and right analog stick OR (2) connecting an external keyboard and pressing the Del key.

In the bios; navigate to the Boot menu and then change the boot order to prioritize the SD card or USB Drive under Boot Order Priorities. Then go Save & Exit and select the Save Changes and Exit option. This change will persist through all reboots. If you want to boot into Windows simply remove the SD Card or USB drive.

Video Walkthrough

Changing the RGB

In EmulationStation press the Start button to open the Main Menu. Then select System Settings and scroll until you see Device LEDS. Under that setting you can choose to turn RGB Off or select from a set of pre-defined colors. The value you set will persist through all future reboots but note your RGB setting will only take effect after JELOS boots.
