      Here's the error message when trying DOSbox:
      /opt/retropie/supplementary/runcommand/runcommand.sh: line 804: /home/pi/RetroPie/roms/pc/+Start DOSBox.sh: Permission denied*

      Indeed a permission related error. I've moved some roms folder by system to a usb key, by creating symbolic links for each system I want to manage roms on the USB key.

      Permission of the original scripts on the MicroSD card:
      -rwxr-xr-x 1 pi pi 271 Mar 22 12:23 +Start DOSBox.sh
      -rwxr-xr-x 1 pi pi 176 Mar 22 12:32 +Start rpix86.sh

      Permission of the scripts on USB:
      -rwxr-xr-x 1 pi pi 271 May 11 12:46 +Start DOSBox.sh
      -rwxr-xr-x 1 pi pi 176 May 11 12:46 +Start rpix86.sh

      Seems exactly the same to me....

        How is your USB key formatted? Also, did you use the method of altering the paths in "es_systems.cfg" to relocate?

          I've not altered the config file, but simply created links for each platform. For example, for the pc platform:
          lrwxrwxrwx 1 pi pi 19 May 11 12:47 pc -> /media/usb0/roms/pc
          drwxr-xr-x 2 pi pi 4096 May 11 15:55 _pc (renamed original folder)

          About usb mount:
          /dev/sda1 on /media/usb0 type vfat (rw,nodev,noexec,noatime,nodiratime,sync,uid=1000,gid=1000,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,errors=remount-ro)

            OK, if you change "noexec" to "exec", it should start launching.

                  in /etc/usbmount/usbmount.conf (if using usbmount)

                    OK, drop to the command line (f4 key), then type "sudo nano /etc/fstab". After that you can add the line "/dev/sda1 /media/usb0 vfat auto,users,rw,exec,uid=pi,gid=pi 0 0". Then hit "ctrl+o" to save, "Enter" to confirm, "ctrl+x" to exit and finish it off with "sudo reboot". That should do it, but we'll see.

                      If usbmount is the superior and preferred method, then most certainly go with that. I might have been a bit too quick to recommend the settings from my machine.
