Running ROMs from a Network Share
-
Hi guys,
I need some help with running my roms from a Synology NAS.
Despite following the guide, I can't get any of my systems or games to appear in RetroPie. I've tried putting a line in autostart.sh which didn't work and I've tried using fstab to no avail :(
I'm running a pre-made image of the latest build - RetroPie 4.4 on a Raspberry Pi 3B+ connected to my home network via ethernet. My Synology NAS is running on IP 10.0.0.10 and has a "Media" cifs share with guest access.
The line I've added to autostart.sh is:
`sudo mount -t cifs -o username=xxxxx,password=xxxxx //10.0.0.10/Media/RetroPie/roms /home/pi/RetroPie/roms
If I try "sudo mount -a" I don't get any errors, but I still don't see what the issue is. I've even tried using the hostname of the server e.g. "SYNOLOGY" in the path and it doesn't work.
Help!

@evh If the share name is
Media
, then the mount command is not correct. You can't mount arbitrary folders inside a share, you should mount the share itself.
My advice is to create a different share and name itRetroPie-Roms
, then follow the docs and add the share to the/etc/fstab
file to be auto-mounted to/home/pi/RetroPie/roms
. Restart and see if the share is correctly mounted, then restart Emulationstation and see if the ROMs from the share appear in the list. -

The docs suggest that the path can contain folders... which I wrongly assumed would work.
sudo mount -t cifs -o username=something,password=something **//REMOTEHOST/path/to/roms** /home/pi/RetroPie/roms

Well, I can confirm it still doesn’t work.
Mounting a cifs share called RetroPie and having all the usual folders inside didn’t work.
I even tried appending the path to 10.0.0.10/volume 1/RetroPie/roms thinking that maybe I needed the volume name but I couldn’t get it working.
I’m almost about to give up which is a shame because I’ve got a NAS full of roms that I want to use and only a 16GB SD card :(

@evh Is the remote share mounted if you issue the command manually ? Does
mount -a
works after you set up the fstab ? Is there an error when you run themount
command ? -

Just in case someone comes into this topic and none of the posts in this thread or the wiki solves their issues (like what happened to me). Here's how I got mine working. I'm using an ASUS RT-AC86U router with a Network Place (Samba) Share on a Raspberry Pi 3 B running RetroPie 4.4.x:
Mount:
sudo mount -t cifs -o username=xxx,password=xxx,vers=1.0 //server/path/to/roms /home/pi/RetroPie/roms
Notice the
vers=1.0
. That was the only thing that would make the mount work for me. I found that option on a Linux support forum.Permissions:
sudo chown -R pi /home/pi/RetroPie/roms
I tried every variation of
sec
,file_mode
, anddir_mode
, but no matter what I did my gamelist.xml, save states, battery saves, etc. would not get created or updated. After chowning the newly mounted shared rom folder, everything worked like a charm. -
@ringnutz said in Running ROMs from a Network Share:
I had the exact same issue. It is not the fstab part that is important here but the options. Specifically one of "nounix,noserverino,defaults,users,auto". I have not deduced which one fixed it, but I am using the Autostart.sh and it works fine as follows
sudo mount -t cifs -o gid=1000,uid=1000,username=USER,password=PASS,domain=DOMAIN,nounix,noserverino,defaults,users,auto //192.168.X.X/SHARENAME /home/pi/RetroPie/roms
Note that you may not need domain above for your share.
After unmounting and remounting the share using the above arguments, I am now able to launch Mame2003 Roms just fine.
I know this is old, but thank you! This worked! Those extra options at the end allowed me to play Mame from my NFS file share, whereas before, everything BUT Mame worked.

I have been racking my brain. I switched from USB to Network share. I have followed everything in the guide, and in this thread. everything mounts properly, I can see everything when I enter the terminal on my RetroPie, or via SSH.
Even viewing the Samba Share via windows Explorer.
But when emulationstation starts, it hangs at checking system config. it will not move past that. I have verified the es_systems.cfg it is all proper, and matches my rom paths exactly.
there doesnt seem to be any logs, i check every log i can think of for emulationstation and they are all blank.

Start Emulationstation with the
--debug
option and post the log you get - in a new topic please where you add the info about your system as requested in https://retropie.org.uk/forum/topic/3/read-this-first. -
@BuZz said in Running ROMs from a Network Share:
I avoid using fstab also, and just add the mount to the
/opt/retropie/configs/all/autostart.sh
script (4.0 feature)cat /opt/retropie/configs/all/autostart.sh
sudo mount -t cifs -o username=something,password=something //nas/retropie /home/pi/RetroPie kodi #auto emulationstation #auto
Maybe it is a stupid question but what username has to be put in? The User, i use as a User on my pi? Or the User on the Server?
-
@snydea the user for the share on your server.
-
@snydea For a better understanding, the username and password is needed to log into the NAS. You don't need the local username and password, because
you're already logged in locally when you are in the text console(edit) the autostart already runs as the local user.sudo
may ask for your local user's password, however, to gain temporary administrative rights to mount the remote share locally. (It will store the passwort for a short time, so subsequentsudo
commands may not ask for it again. edit: And on the official RetroPie image, its password request is disabled alltogether.)I hope I could make myself intelligible. :) I always find it better to understand something than to just know the necessary actions.
-
A much better way (for me) is using overlay file system, that way even if it can't connect to my server I can still play the games stored locally on the pi.
I have all the MAME ROM's on a share on my Windows PC, and this is what I put in autostart.sh:
(sudo mount -t cifs //10.88.44.17/Emu /net/emu -o username=Guest,guest,forceuid,uid=pi,ro,nounix,vers=3.0 && sudo mount -t overlay overlay -o lowerdir=/net/emu/Mame/roms,upperdir=/home/pi/RetroPie/roms/arcade,workdir=/home/pi/overlay.work /home/pi/RetroPie/roms/arcade ) &
emulationstation #autoEverything starting with ( and ending with & is supposed to go on one line.
Now it will mount the Windows share on my desktop 10.88.44.17/Emu in /net/emu (you need to create an empty directory there first), and I have all my MAME roms under Mame/roms under that share, and then it will underpin what was already in RetroPie/roms/arcade and when you make changes it gets written to that directory, but it can access all the files from my server, which is mounted read-only.
Because I do the mounting in a "( ) &" subshell, it will run in the background and not prevent or slow down the normal startup if the server can't be reached.

Re: Running ROMs from a Network Share
I am trying to mount in autostart.sh using the following command:
sudo mount -t cifs -o vers=1.0,username=roms,password=password,nounix,noserverino //192.168.0.5/roms /home/pi/RetroPie/roms
When I run this manually from the shell it works fine, but when I put it in autostart.sh it doesn't work (the roms directory is empty).
Suggestions on how to debug this?
-
@heythereharpo A more elegant way to mount shares on startup would be to use the
/etc/fstab
. See here for one of the many how-tos on the web:https://wiki.ubuntu.com/MountWindowsSharesPermanently
Suggestions on how to debug this?
Put a
> /home/pi/mount.log
behind the command to save its output into the text filemount.log
in the userpi
's home directory.A single
>
will overwrite the file every time. Use>>
to append the output to an existing file. -

Thanks @Clyde , I went the SystemD option. I found this page very helpful in addition to the ones you shared: https://michlstechblog.info/blog/systemd-mount-examples-for-cifs-shares/
Sharing this info for others that are trying to mount to a share on an old SMB 1.0 device.

I am running successfully ROMs from my network share using the modification of autostart.sh file. However:
-
when setting "parse XML gamelist only " to "OFF" the startup of ES is extremely slow - too slow to be workable. I then switched to the next option below.
-
when setting "parse XML gamelist only " to "ON", the startup of ES is fine, however, now loading the artwork (I presume) is extremely slow - too slow to be workable as well.
Any ideas of speeding things up in either options?
this is what I have added in the autostart.sh "sudo mount -t cifs -o username=pi,password=raspberry,nounix,noserverino //192.168.1.110/roms /home/pi/RetroPie/roms" where pi is an account I created on my windows 10 server and roms a share (pi has read/write access).
Any help would be very appreciated....even if it is confirming running off network is so slow it isn't a viable option. If so, then I will abandon it.

@kdeman The reason for both effects it the same – networks are much slower than local storage, and Emulation Station reads the artwork of a game only when you reach it while browsing the list.
Apart from any potential network tweaks that don't really change this ugly fact, the best way to speed up things is to set Parse Gamelists Only to ON and store the artwork locally. Most scrapers have an option (not) to store the media files in the rom folders.
