Emudeck_SMB_Saves

A small batch of scripts that enables syncing of saves between your Steam Deck (or other Linux device) and a local SMB share.

Due to the complexity of Emudeck's save structure, I made a set of scripts and services that follows all the symlinks to push/pull saves from the right places.

It's intended to pull network saves on Deck startup, and sync your saves to the network every 15 minutes.

Assumes you have a network storage mounted already - if you don't, here's the line I added to my /etc/fstab (yours may vary based on user permissions, etc.):

Uses rsync -avhu, which basically means it will overwrite a save if the one being pushed/pulled is newer.

//<server_name>.local/Games /mnt/<server_name> cifs guest,iocharset=utf8,nofail,_netdev 0 0

On the Deck this mounts my folder to /var/mnt/<server_name> for some reason, I'm not sure why, but keep in mind that there may be a discrepancy there.

I've only tested this a bit, it works for me, but I take no responsibility for anything that breaks if you choose to use this!

Steps:

1. Run generate_nas_to_deck.sh and generate_deck_to_nas.sh
2. Put the newly created nas_to_deck.sh and deck_to_nas.sh in /home/deck/Emulation/ on your Steam Deck
3. Put startup_network_save_pull.service, timed_network_save_push.service, and timed_network_save_push.timer in /etc/systemd/system/
4. Run sudo systemctl daemon-reload
5. Run udo systemctl enable startup_network_save_pull.service
6. Run sudo systemctl enable timed_network_save_push.timer

You should now be pulling saves from your network drive on startup, and pushing them every 15 minutes!

Note: I can't get shutdown_network_save_push.service to work on shutdown, it doesn't even execute, not sure what the reason is. Keeping it here for later debugging.

Another note: I've got /home/deck/Emulation/roms symlinked to /var/mnt/server_name>/Emulation/roms, which is also great because I don't have to move games between systems anymore:

ln -s /var/mnt/server_name>/Emulation/roms /home/deck/Emulation/roms 

To do: Set up a startup/timer script that works with Windows
