      Hi, yes this would be great if these files were symbolic links. But I am doubting it, since I was verifying where the symbolic link is going:

      If I type in the command shell:
      readlink -f ~/RetroPie/roms/gb/Pokemon\ -\ Blue\ Edition.gb

      I got the output:

      /home/pi/RetroPie/roms/gb/Pokemon - Blue Edition.gb

      In my opinion it could be, that it is a symbolic link to itself, where I think that this means it is not a real symbolic link but the file itself.
      For a symbolic link I would expect:

      -> /media/usb/retropie-mount/roms/gb/Pokemon - Blue Edition.gb

      (a link to the USB drive)

      By the way, I read the tutorial in the thread creation again and I realized in the last section the small sentence:

      Now transfer ROMs either directly to the USB drive, or via any of the usual methods (aside from using the automatic USB copy, obviously!)

      In my opinion, this means that a direct copy to the USB-drive is not able to work with the "automatic method", but only with the manual method, doesn't it?

        @retrochip it might be your NTFS drive. the guide states fat32.

        Now transfer ROMs either directly to the USB drive, or via any of the usual methods (aside from using the automatic USB copy, obviously!)

        In my opinion, this means that a direct copy to the USB-drive is not able to work with the "automatic method", but only with the manual method, doesn't it?

        i don't understand you, here. if your links aren't working, it doesn't matter if the automatic copy has happened or not. you have problems before that.

          Perhaps, I expressed myself a bit unclearly:
          The links are working, if the ROM is in bother folders (/home/pi/RetroPie/roms/gb/ and /media/usb/retropie-mount/roms/gb/)
          So the games are updated after a restart of the emulation system.
          If I delete a rom file on one both folders, then the ROM in the other folder is deleted as well after a certain time. It doesn't matter if I do it on the SD-Card or the USB-Drive. So there is some kind of a syncronization process running. But the interesting question is, if the file in /home/pi/RetroPie/roms/gb/ is really a symbolic link to /media/usb/retropie-mount/roms/gb/. Then everything would be perfect ;) But as stated before, I doubt it because of the output of the readlink command. Unfortuanetly I do not know more about the sync process.
          So it could have something to do with the automatic copy or the manual copy. Does anyone know the author who has written the tutorial and could send me some contact details via PM?

            I think you are over-complicating the thought process. It doesn’t “Sync” it only creates a pointer to the rom on your USB Storage.

            But there are 2 independent ways to look at this.

            1. You load ROMs from a USB onto the Raspberry Pi from a USB stick. In which case, once that has taken place there is no need for the USB device. The ROMs are now on the SD card.

            2. You RUN ROMs off of the USB device, and the ROMs live on the external device. In this case there will be a “Link” to the external drive data.

              Hey, yes I understand. And my question is how do I tell retropie to do as you described in your second point?
              Until now I thought it doesn't matter if I use the automatic mount or the manual mount to go your second way.

              @dankcushions
              I rechecked it with a USB-Drive which is newly formatted with FAT32. I still have the same behavior. (same output for readlink command as before) So it seems to be no problem, that I have a drive with NTFS.

                I have used the Official method of “RetroPie-mount” that you describe and it worked fine for me. But I prefer the Easy-Hax toolkit method. Maybe you will have more success with that.

                The thing I like about this is you can keep some ROMs on your SD card (if you want to), while also being able to plug in the External drive and reboot to have access to that as well. Win / Win

                  i wrote the tutorial :)

                  i guess i just don’t know what the problem would be. this is basic functionality of retropie and should work ‘out of the box’. it works for me and many others. i don’t know how i can assist you other than if you look at the usb functions in the scripts and work through it line by line.

                    Well, there's also the KISS principle – keep it simple, stupid. In this case, that would be having all roms either on the card or on the usb drive.

                    I understand your desire to adjust the system to your personal preferences, but there is a point where the possible gain is not worth the effort (and that comes from someone who manually set up his usb mount to only some rom folders, but also with over 11 years of Linux experience).

                    That said, it would be helpful for further help in this matter if you describe your setup method step by step including the exact commands used and config files created/changed. And no, the mere reference to the How-To you used isn't enough.

                      If you configured your retropie, that you run the ROMs OFF of the USB device, with a symbolic link to the external drive data. Could you please provide the output, what you get if you run the readlink -f command in the /home/pi/RetroPie/roms/ folder for a specific rom file. Then I would at least know how it should look like.

                      Thank you!

                        I think I got it now :)

                        I understood that if I access the subdirectories of /home/pi/RetroPie I always access my USB-drive. The subdirectories are not on the SD-card anymore and everything is on the USB-drive.
                        I verified it with the following command (for anyone who had the same problems):

                        df -P /home/pi/RetroPi | tail -1 | cut -d' ' -f 1

                        Output:
                        /dev/sda1

                        As you can see here (/dev/sda1) equals my USB-drive:

                        pi@retropie:/home $ df
                        Filesystem 1K-blocks Used Available Use% Mounted on
                        /dev/root 7928236 2083396 5419064 28% /
                        devtmpfs 378828 0 378828 0% /dev
                        tmpfs 383436 0 383436 0% /dev/shm
                        tmpfs 383436 5460 377976 2% /run
                        tmpfs 5120 4 5116 1% /run/lock
                        tmpfs 383436 0 383436 0% /sys/fs/cgroup
                        /dev/mmcblk0p6 58234 21480 36754 37% /boot
                        /dev/sda1 1953511420 958316104 995195316 50% /media/usb0

                        So the readfile command is therefore of course always refering to itself.

                        In total, this is exactly the behavior I would like to :).

                            @clyde not trying to make things more difficult. Just giving another option in-case he can’t get the official method to work.

                            In my case I don’t scatter ROMs onto either storage media. I use my hard drive for the CD based games and then when unplugged it still holds all my cartridge systems on the SD Card.

                              Did you follow these steps EXACTLY. Note is says FAT32 and NOT NTFS. If you are still on NTFS on your external USB drive you will have to reformat it to FAT32. That should fix the issues ... I had similar issues with an external USB on a PS3. Tried for days (literally) to get it to work. Converted the drive from NTFS to FAT32 and it worked straight away. Not sure why NTFS screws it up but it does

                              First Update the RetroPie Setup Script
                              Re-Enable the USB ROM Transfer Service
                              Format your USB drive to FAT32 per directions above
                              Create a folder called retropie-mount on the USB drive
                              Plug into Raspberry Pi
                              It will proceed to automatically copy the RetroPie folder AND all of its contents (you may need to reboot to start the copying)
                              

                              Note, that you MUST disable the USB ROM Transfer Service AFTER everything has been completed and copied over, that can confuse things as well

                              If your USB drive is NOT FAT32, have a look at these links to explain how to convert from NTFS to FAT32. It can take quite some time depending how full your USB drive is. Be patient if you do convert it will work eventually and DO NOT be tempted to stop it. Your USB drive must be plugged into your PC though ....

                              NTFS is the preferred format these days as filesizes over 4GB are not supported in FAT32 and will cause a copy error if you try to, but as everything on RetroPie is well under 4GB filesizes that isn't an issue here. Even if you try MAME CHD games they are all under 4GB. Not that the PI3 will run all of them, but that option is there if you wish to try once you've got it running

                              https://www.disk-partition.com/tutorials/convert-ntfs-to-fat32.html

                              If you are not 100% sure what filesystem your USB drive is, in the My Computer folder, simply left-click your USB drive once and it should tell you what it is either NTFS or FAT32. If not, right-click your USB drive and choose'properties' at the bottom of the drop-down menu it will then show another windows with the filesystem clearly shown as NTFS or FAT32. Pretty much every USB hard drive I've bought is now already NTFS format

                              If nothing works, you might have to rebuild an image from scratch. I've done it this way in the past and installed a minimal OS image from the NOOBS option, and rebuild RetroPie manually. More work, but guaranteed to work if the RetroPie image is causing headaches

                              Use the NOOBS_LITE download which is the bare minimum and you then choose what OS to install. But you NEED an internet connection. Preferably an ethernet one as its much faster than the PI's wireless connection

                              https://www.raspberrypi.org/downloads/noobs/

                              Then follow these steps EXACTLY. If you have already installed the OS using the above method, then just skip to the INSTALL RETROPIE step and work from that. It does work this way as I've installed it this way when I've also had issues with the RetroPie pre-built images in the past

                              https://github.com/RetroPie/RetroPie-Setup/wiki/Manual-Installation

                              "Custom" hard drives always cause problems for future updates, as its basically just shovelware. They install functioning software package and just load everything onto the drive and you are left with basically with zero after sales support and hundreds of games that are not suitable for that set-up

                                NTFS is supported by the retropie-mount routine. It's working 100% fine here with a 3TB NTFS file system on a external portable hard drive.
