Retropie not finding Roms on External Hard Drive

[bkay]

I am having trouble getting my Raspberry Pie 3 model B with RetroPie to find my roms on my 1 TB WD Passport external hard drive. I am new to RaspberryPie and RetroPie and I have been trying to figure this out. I want it to run the roms straight from the external hard drive rat her than the SD card. I did as much searching on the web to figure this out. I found out the drive is located at /media/usb0/ and changed the paths using sudo nano /etc/emulationstation/es_systems.cfg. The path on my hard drive is for example: F:/nes so I changed the path on retropie to /media/usb0/nes. It still doesnt seem to find the roms. Please any help would be greatly appreciated.

sudo df -h to see what your drive is named.

Should look something like this:

• Filesystem Size Used Avail Use% Mounted on
  /dev/root 15G 2.8G 11G 21% /
  devtmpfs 364M 0 364M 0% /dev
  tmpfs 368M 0 368M 0% /dev/shm
  tmpfs 368M 5.2M 363M 2% /run
  tmpfs 5.0M 4.0K 5.0M 1% /run/lock
  tmpfs 368M 0 368M 0% /sys/fs/cgroup
  /dev/mmcblk0p1 57M 20M 38M 35% /boot
  /dev/sda1 30G 1.5M 30G 1% /media/usb0

The drive you’re looking for is the one that resembles your USB drive. Now, sudo nano /etc/emulationstation/es_systems.cfg

<system>
<name>amiga</name>
<fullname>Amiga</fullname>
<path>/media/usb0/amiga</path>
<extension>.sh .SH</extension>
<command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 SYS amiga %ROM%</command>
<platform>amiga</platform>
<theme>amiga</theme>
<directlaunch/>
</system>

Change the path for every emulator in the list.

When you’re done, hit CTRL + O then enter to save the file and then CTRL + X to exit the nano editor.

@Ostego editing the file is not recommended. Better to symlink or mount the USB over existing from location.
