      Retropie 3.7 on RPi3B. Trying to configure both following the wiki pages, but launching the +LAUNCH scripts nothing happens, apps abort and return to emulationstation.
      Launching the binaries from the command line (outside emulationstation) works.
      Cannot figure out the problem... could you please help me?

      Tnx!

        please post the contents of /tmp/runcommand.log after launching.

          The log BuZz requested should ultimately delineate the problem, but it sounds like the scripts have lost their permission to execute in some way. Have you relocated your roms folder in any way? If so, have you moved it to an external drive not formatted to ext4? If not, you can try running "chmod +x /path/to/+LAUNCH/" with the actual path to the affected scripts of course.

            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.

                    Sorry, my unix/Linux memories are almost lost.. how to do that? editing the fstab to define a fixed mount?

                        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.
