| # On LG WebOStv, RetroArch only have access to a few jailed folders so to run games on a usb drive, | |
| # we need to 'merge' the USB mounting point with one of those jailed folders using OverlayFS. | |
| # The scripts on folder '/var/lib/webosbrew/init.d/' will run after every tv boot. | |
| # Remove the $STARTUP_FOLDER/$SCRIPT_TO_RUN_AFTER_BOOT and reboot to revert the change. | |

| # Steps: | |
| # - Copy this script to a pen drive and insert it to the TV | |

I have rooted lg c3.
On my fat32 flash device parent directory i created folders: tmp, on tmp folder i created sda folder, then sda1 on tmp/sda.
Then i placed file add_usb_drive_to_retroarch_media_folder_install.sh on this tmp/sda/sda1 folder.
Then i connected my rooted tv to webOS Dev Manager.
On terminal i entered: cd /tmp/usb/sda/sda1/
Then checked that file exist: ls
Then i successfully run the script and tv rebooted.
Then i put some snes and smd roms to folder /tmp/usb/sda/sda1/ - but retroarch still dont see my usb flash drive...
I tried to reboot tv, i tried to put roms on sda or sda1 or tmp or parent usb drive folders - still do not see it. Yes i run snes or smd retroarch core, and use properate roms extension.
I uploaded roms on tv rom with webOS Dev Manager - and retroarch perfectly see and run them. But usb flash drive still do not work.
Any suggestions? Thanx!
Hi Shienok,
When you plug your usb drive to the TV, the folder "/tmp/usb/sda/sda1/" should be automatically created for you by the TV itself on its filesystem - the path may vary depending on the TV model.
On the usb drive, you only need the script "
add_usb_drive_to_retroarch_media_folder_install.sh" and your roms.
lg c3, rooted, ver.03.20.17
Tried 2 usb flash drives, formated fat32.
On empty flash drive i put only 1 file add_usb_drive_to_retroarch_media_folder_install.sh
Connected to tv via webOS Dev Manager Terminal
Entered: cd /tmp/usb/sda/sda1/, then entered: ls - it shows me only 1 file add_usb_drive_to_retroarch_media_folder_install.sh.
Then i entered: sh add_usb_drive_to_retroarch_media_folder_install.sh
It succesfully installing and rebooting tv.
After that no files or folders are creating on usb flash drive, only this 1 file add_usb_drive_to_retroarch_media_folder_install.sh as it was before all the procedure... I put roms on flash - retroarch do not see anything(
Are the roms zipped? It must be uncompressed to retroarch to find it.

no, all roms are unzipped of course
On RetroArch, if you go to "Load content" and select "/media/internal", what do you see?
Also, please send the output of following command with the usb drive attached:
ls -la /var/palm/jail/com.retroarch/media/internal/
And
cat /var/lib/webosbrew/init.d/add_usb_drive_to_retroarch_media_folder
And
ls -la /var/lib/webosbrew/init.d/add_usb_drive_to_retroarch_media_folder
screen 1 with donkey kong sfc rom - this rom i uploded on tv memory with the help of webOS Dev Manager.
screen 2 with above 3 commands on terminal
Everything looks okay.. could you please add all your roms to the usb drive and repeat all steps, adding the following?
ls -la /tmp/usb/sda/sda1/
I'm having an issue as well.
Here is output of script:
Fixed after reformatting usb using NTFS (overlayfs: filesystem on '/tmp/usb/sda/sda1' not supported)
@maatthc I have the same problem. run the script, TV rebooted, no new files or folders in /media/internal/ seen in retroarch.

Edit: nevermind, it was the file format as well. Apparently only NTFS works, which is odd for a Linux system,
