Welcome to the Lemuroid FAQs!

Where does Lemuoroid stores save files?

Lemuroid saves directory is "/sdcard/Android/data/com.swordfish.lemuroid/files/saves", while states are store stored in "/sdcard/Android/data/com.swordfish.lemuroid/files/states".

Can I import my save files from Retroarch?

Yes you can. Just disable Autosave and copy the content of your Retroarch saves folder into Lemuroid saves folder.

How can I manually backup my save files?

Just backup Lemuroid saves and states folders and you should be good to go.

How does Lemuroid recognize my files?

Lemuroid scans your files and tries to match them with a local copy of the Libretro DB. A ROM is detected when at least one of the following is true:

  1. The CRC32 matches a db entry
  2. The file name matches a db entry
  3. The file extension uniquely identifies a platform (.nds, .n64, .gba, etc...)

Single file zip archives are also supported.

How can I forcefully import ROMs which are not automatically detected?

You just have to copy it into the internal ROMs directory "/sdcard/Android/data/com.swordfish.lemuroid/files/roms/system_name", replacing system_name with one of the following: psp, fbneo, gba, gbc, gb, nes, snes, sms, genesis,

This only works with uncompressed files. If this method fails, those ROMs are probably unsupported.

I'm trying to scan my Downloads folder but it doesn't work. What can I do?

On some devices this just doesn't work, you should move your ROM files into another directory using a file manager.

Why aren't my FinalBurn Neo ROMs detected?

Lemuroid officially support only non-merged romsets which have the same CRC32 code as Libretro DB. If you still want to use these files see "How can I forcefully import ROMs which are not automatically detected?".

I generally play with Retroarch on another machine, can I share saves with Lemuroid?

Yeah, I generally use Syncthing to keep the Retroarch save folder in sync with Lemuroid. Just make sure you disable Autosave or your save files might get overwritten by older versions!
