It is necessary to access the Lakka filesystem in order to accomplish tasks such as adding ROMs or BIOSes. Access to the filesystem also makes it possible to content like screenshots or savefiles from Lakka. There are two overall approaches to gaining access to the Lakka filesystem:
Lakka can also be configured to use ROMs that are served from a NAS for users who are comfortable working in a Linux shell environment.
The editable portions of the Lakka system can be found in the following folders. Note that these the only folders which are made accessible via SAMBA – accessing other areas of the filesystem requires a different approach.
Samba is a service that you can enable in Settings->Services which allows other computers on the local network to transfer files to Lakka via the CIFS/SMB protocol. Only the most important folders are accessible via Samba.
Windows, OS X, and most Linux distributions should be able to navigate directly to Lakka’s Samba share by entering
\\lakka\ into their file browser. If you cannot reach the Lakka system by name, it may be possible to reach it by IP. Once you have determined Lakka’s IP, enter that address in the file browser as with the Lakka name earlier, such as
This method requires that SSH be enabled in Lakka, but it is faster than SAMBA. It will also require that you have and be familiar with operating SCP-enabled file transfer software or an SSH client capable of managing SCP file transfers.
You may be able to connect to Lakka via the name “lakka” in your SCP client. If not, you will need to find the IP of your Lakka box. The credentials for SCP are the same as for SSH: username root and password root.
In a terminal, copy the files over network using the scp command:
scp -r roms/* [email protected]:roms/ scp -r bios/* [email protected]:system/
This method consists of mounting the SD card, flash drive, or hard drive where Lakka is installed on a host workstation running Windows, Linux, or OS X. It is not convenient if you have installed Lakka on a device with internal storage, since you would have to connect the drive to another PC. But it works well for ARM boards, where the storage media is an SD card most of the time.
If you’re on Linux, you can mount the second partition of your SD card/USB pendrive, and access the files on this partition. This way, you don’t need network connection, and you can access all files on your drive, including RetroArch configuration files located in
ext4 partitions from windows is not supported natively but you can install a driver.
Lakka offers the possibility to store your ROMs on an external USB drive.
Your USB drive must be formatted as FAT, NTFS or ext2/3/4. Store some ROMs on it, and plug it in your Lakka Box. The partition will be mounted automatically in a new folder under
/storage/roms/, and your ROMs will appear in the menu. Please note that installing Lakka itself to an external USB hard drive is also an option.
Note: If you are using Lakka for PC in live USB mode, you should be able to access the hard drives of the host computer.
