Seamless Co-op Archive Converter
🎮 **Quickly convert archive formats and enjoy a seamless online experience! **
✨ How to use
- Put the program files into the game folder (requires the seamless online module to be installed)
- Run the program and it will prompt you to go to the archive folder (usually located at: `C:\Users\username\AppData\Roaming\EldenRing\Random Numbers`)
- If there is only one save file, congratulations! The program has automatically converted it to .co2 format
- If there are multiple .sl2 files, please select the file you want to convert
- Once the conversion is complete, you can choose to launch the ERSC launcher immediately or exit the program
💡 **Tip**: Want to revert to the original save file? Just run the program again!
🔧 Technical Description
Currently the program simply changes the file extension from .sl2 to .co2, this can also be achieved by manually renaming the file. However, there are rumors that Elden's Circle will automatically remove mod items when converting mod saves to vanilla in recent patches.
I'm thinking of developing a safer version that can remove all seamless online items while the game is running (by editing the game memory, with EAC turned off), and then convert the mod archive to the original archive to ensure that the archive does not contain illegal items.

Install & use Install: follow the bundled instructions
- Unzip the archive from playbuff and read the bundled readme / instructions first.
- There is no universal mod manager for this game: some mods replace game files directly, some go into a game-specific Mods folder, and some need a game-specific community loader or tool first — follow the bundled readme.
- Place the files exactly as the readme says; mods with listed dependencies need those installed too.
- Launch the game to confirm it loaded; some games require enabling mods in settings or an in-game mod menu.
Install locations vary a lot between games and mods — the bundled readme is the most reliable guide.
