How to add usb hdd storage as second storage for games in retropie

[martinex]

I'd like to add hdd usb storage to retropie/raspberry. How can I setup to load to list game, games from microsd and usb hdd combinated?

I do not want to auto import games from this hdd to microsd.

@martinex Running ROMs from a USB drive, even if the retropie-mount method is the easiest, in most "stationary"- or "just this system on the raspberry & external device just meant for this"- cases the manual mount is IMHO to be prefered (as is ext4 for the external drive (IMHO again)).

Edit: Sorry, haven't realized what exactly it is that you want

games from microsd and usb hdd combinated?

I don't think that having "roms" both on SD and external storage freely mixed is an easy task. Having certain folders on the SD card and others on the external mount can be done via the manual mount method and mount-points. But that what you are asking for is IIRIC under the context of "union mounts" and with such I have no experience.

Hey there ok if this helps try this you will be able to use sd and hdd just relocate the games path

you can edit the file in /etc/emulationstation/es_system.cfg so all you do is change the locations of your roms you need edit this by ssh which you can do from phone or pc
Heres and example

<system>
<name>3do</name>
<fullname>3DO Interactive Multiplayer</fullname>
<path>/home/pi/RetroPie/roms/3do</path>
<extension>.chd .cue .iso .zip .CHD .CUE .ISO .ZIP</extension>
<command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 SYS 3do %ROM%</command>
<platform>3do</platform>
<theme>3do</theme>
</system>

Above you will need to edit <path> so instead of home/pi/ you will use the mounted hdd path of the games.

I know it might be alot of editing but just back it up when your done
Hope this helps and good luck.

Retropie is monting this hdd automatic.

/dev/sda1 229G 2.9G 214G 2% /media/usb0
using ext4 on this hdd.

No, that's not supported - a system can have only one path in EmulationStation.

@mitu I just check it, doesn't work that way.
