ELDEN RING Reforged Compatibility: Seamless Coop by LukeYui

Seamless Coop is a popular mod by LukeYui which allows multiplayer cooperation in mods.
ELDEN RING Reforged adds many fixes for Seamless Coop issues, and many mechanics that integrate with cooperative play.

Here's a basic guideline on how to set it up with Reforged.

1) Download the version 1.5.1 (NOT 2.0.0) of Seamless Coop from Nexus: https://www.nexusmods.com/eldenring/mods/510

!!! DO NOT USE VERSION 2.0.0 !!!

2) Install it using the Seamless Coop instructions. Extract the contents of the archive into your "ELDEN RING\Game" folder, located in your Steam files.

You can check your ELDEN RING properties in Steam and pick "Browse Local Files" to find this folder.

You should now have an "ELDEN RING\Game\SeamlessCoop" folder, with a DLL and INI file inside.

3) Configure the newly extracted "seamlesscoopsettings.ini" file according to Seamless Coop instructions.

4) In the "seamlesscoopsettings.ini" file, please configure the save extension to be "err":
savefileext = err
5) Run the mod via the Reforged Launcher EXE. Reforged should now be launching properly with Seamless Coop. If not, please check the previous steps again.

Known issues:
- Seamless Coop is generally a fairly buggy experience; most bugs can be attributed to Seamless itself.
- The Codex of the All-Knowing functions very unreliably in coop, especially when it comes to
giving all players the same progress.
