Lost Grace Found!

What is this?

Lostgrace is a service that syncs your Elden Ring Seamless Coop save, saving you the hard work of plugging and unplugging a $2 thumb drive all the way over there.

But seriously. It could be helpful if you are trying to sync your save to a handheld that only has usb-c/limited ports, or you really don't want to format that thumb drive with that sweet Arch Linux distro on it.

Using Lost Grace

1. Play some Seamless Coop if you don't have a save.
2. Register here. You will immediately get a code to use for syncing your saves after you register. Make sure you save it.
3. Download the client to each of the machines you would like to sync. Get it here.
4. Extract the zip. Edit the user.config with your favorite text editor. Set name = your_name_you_used_to_register and key = your_key_from_registration_step.
5. (Optional on Windows. Required on Linux) Set the path of save the save directory if it is not in %AppData%/Roaming/EldenRing. If there is just a single directory underneath ../EldenRing/, good to go. Otherwise, replace path = auto with path = the_path_to_your_save_file. There will be an error if auto does not work.
6. (Optional) If you are not using the ersc save format (co2), replace ext = default with ext = .your_extension. Ex: ext = .abc
7. Run the lostgrace executable (lostgrace.exe on Windows) to sync. Run it with the -d <direction> flag to either upload (-d up) or download (-d down) your save.

Misc. Details

• Use at your own risk. I have tested this on a few configurations. There could be bugs. The Dollar General web server I am running this on might choke.
• Testing done on latest Windows 11 and latest Ubuntu LTS.
• You (currently) get one save slot to sync.
• You (currently) have to manually sync by running the lostgrace application.
• Syncing a save not in this system will set it as the latest save, no matter how old or new it is.
• There is a size limit for the save files.
• While this is still free/beta, unused saves will be deleted after six months of inactivity.
• Your save file is (most likely) stored under a different compdata directory under Linux if you set ersc_launcher up as a non-steam game. Your normal and coop save are colocated on Windows.
• Elden Rings saves are about 30MB. They take about a second(ish) to upload/download due to file operations (think about how steam takes a second or two to sync with the cloud). Do not mess with the save while this is happening. I know I am asking you to not hit the big red button.
• If you enjoy this. Do not abuse it. I mean, this is going to be way better than steam cloud. Just not yet.

Planned Features/Goals

• Proof of Concept.
• Users other than my mom.
• Multiple save files.
• Auto sync.
• Sync key regen if you lose/compromise key.
• Prevent foot-guns when downloading/uploading. There is no system in place to detect if your save is current or not.
• Register/log in from client.
• It would be cool to support other games/mods that do not use Steam or cloud saves.
• Don't deploy on Fridays.
• Rewrite everything in Rust. The borrow checker, parameter lifetimes, and Arc Mutexes can't be that bad.
• Rewrite everything in their original languages since I am too Grug brained to maintain a Rust project.
• Split each page/feature into a microservice on K8s.
• Dissolve company because it costs a million dollars a month to run each page/feature as a microservice on K8s.

Closing Remarks

I use VIM by the way.

I use Arch by the way.

If you got this far, Thank you. I had super fun developing this. I hope to introduce more features (that make sense) in the future. There were some speed bumps that made this a little tricky here and there. Error logs were my friend.
