I recently purchased a 32gb USB stick to store my roms on.
Copied everything I wanted to the stick, make a symlink with the following command (as somebody else suggested in the forums):
ln -s /media/usb/roms/ ~/RetroPie/roms
After a reboot the roms were seen and all was well…exceeeeept:
NES/SNES/Megadrive/gba just will not load. runcommand.log is empty.
I expected at this point that none of the emulators would work but much to my surprise FBA and the PSX roms loaded fine.
Also it seems the Selph’s Scraper has the path hardcoded into it and it will not fall for the symlink trick.
Any ideas on the matter?
Thanx!11/08/2015 at 14:52 #109389
Perhaps some additional info after some searching:
The stick is FAT32 formatted, although it should not matter, perhaps it does?
The stick is mounted as read only and I cannot get it to mount as read/write. Yet again I would not expect this to matter but again: perhaps it does?
Is the symlink approach the wrong one? I could not find where to set the path where retroarch looks for its files as it seems online guides apply to 2.6 and not 3.X.11/09/2015 at 02:20 #109444
I’m new to this as-well, i tried what someone else suggested, editing the emulationstation/es_systems.cfg
by pointing it to my USB folder
But that is not working either. i have formatted my usb to EXT4 and the emulation I’m trying is FBA
Its working when i put the roms on the SD, but not of the USB11/09/2015 at 04:13 #109449
yup gettin the same problem11/09/2015 at 05:07 #109452
I have all of my ROMS on a 128GB thumbdrive with the es_systems.cfg for all systems pointing directly to my USB drive, and it works great.
A few things I discovered in the process:
1. I had to get rid of the tilde “~” in the roms path when pointing to my USB stick. This is Linuxese for ‘go to root’.
2. I had to be sure where Retropie saw my stick. In my case it was USB0.
So my roms path for SNES looks like this:
This works well for me, but I am looking into using symlinks in the future because every time I update my systems I have to re-edit my es_systems.cfg file… which is a pain.11/09/2015 at 09:40 #109456
o, so how can i change the permissions so i can set the drive to read/write so i can add files via filezilla mac.
oh, symlinks i’d be interested in using those too, but have no idea how

Changing the paths in /etc/emulationstation/es_systems.cfg did not work for me.
@momaw27: are you running 2.6 or 3.X?11/09/2015 at 17:39 #109479
So this is what i did to get my to work retropie 3.1
I went to /home/pi/RetroPie/roms
Deleted my rom folder (fba)
and created a symlink like this
ln -s /mount/usb0/fba /home/pi/RetroPie/roms
now all my roms from my usb are showing
as well as all my images from using the scraper
now i need to look into deleting the gambles games from my list and racing games11/09/2015 at 18:48 #109482
@fvargasfrank: the ones that were already scraped will show properly, running a new scrape will result in an error. And oddly, FBA works with the symlink, just not other emulators.
Happy it works for you but, sadly, does not solve our problem haha!
oh and PS: gambling games ok but racing?! Come on! 😛11/11/2015 at 22:26 #109678
Just tried the snes rom super mario, I created a hyperlink just as before and then i change the emulator to snes9x and the rom loaded11/15/2015 at 11:49 #109963
So it seems emulator related. I will have a look at the different emulators although I would like the Libretro ones to work as they seem to work best.
Is this an issue that is perhaps being adressed? As it seems some people manage to run them off external drives without any troubles.
Thanx for the tip!11/15/2015 at 19:40 #109976
I’d recommend making links one system at a time. Aside from that, check for case sensitivity and emulator file type compatibility.11/16/2015 at 04:21 #109998
symlinks should work fine. i use them with all the systems, and the sselph scraper. if your symlink is set correctly, the rom file structure should look exactly the same to anything accessing it, as if it was in the normal place.
the only problem i had was making sure the usb auto-mounted each boot, and with the right permissions. i can’t remember how i did this, but as a linux newbie i just googled until i found something to copy 🙂 it was something to do with fstab and fat32 permissions. my /etc/fstab looks like this:
proc /proc proc defaults 0 0 /dev/mmcblk0p1 /boot vfat defaults 0 2 /dev/mmcblk0p2 / ext4 defaults,noatime 0 1 # a swapfile is not a swap partition, so no using swapon|off from here on, use $ UUID=E44B-FC4E /media/usb vfat nofail,user,umask=0000 0 2
(last line is the usb)11/16/2015 at 10:52 #110019
@jedimaster666: unfortunately per system links do not work either. As stated above not all systems are affected, strangely enough. It seems more emulator related than anything else as switching to some other emulators for, say, SNES work (although these are not the emulators of choice, as one would prefer the libretro ones).
@dankcushions: did you symlink the roms folder in its entirety? I take it you are running 3.X? So I take it your USB stick is read write? The USB stick mounts fine each boot, just as read only. I altered the SRM directory to reside on the SD as the size is not that big of a problem11/17/2015 at 11:32 #110104
i’d previously manually set up the symlinks for each rom folder, but i’ve just done a re-build and attempted to do it with one link of the whole folder (i copied the contents of the stock roms directory to my stick beforehand), and it worked fine. saves time, cheers!
my USB stick is read/write (thanks to that fstab line) and i’m running 3.2.1 (although it worked fine before)02/07/2016 at 15:43 #116422
