How to install Seamless Co-op Mod for Elden Ring

---

Prerequisites:

• The latest Version of Elden Ring
• Seamless Co-op Mod (Instructions for installing can be found on the Mod's Page)
• Goldberg Steam Emulator
• Radmin, Hamachi or ZeroTier

How-To:

1. Download and extract Goldberg SteamEmu
2. In Elden Ring's Game Directory, make a Backup of steam_api64.dll (eg: rename it to steam_api64.dll.backup)
3. Copy the steam_api64.dll from the Golberg Folder to your Elden Ring Game Directory
4. In the tools Folder of Goldberg, drag the Backup of steam_api64.dll you made onto the generate_interfaces_file.exe. This should generate a steam_interfaces.txt File
5. Navigate to your Roaming AppData Folder. Found in C:\Users\USERNAME\AppData\Roaming (You can also get to this by opening run (Win + R) and typing %appdata%). Find "Goldberg SteamEmu Saves", then the "settings" Folder. Change the Contents of "account_name.txt" to whatever Username you want. Then open user_steam_id.txt and change the Number slightly. This must be different for every Person you will be playing with, so you should coordinate having a different Steam ID
6. Download and install Radmin or a similar Program
7. Create a Network, and have you and your Friends connect to it. After doing these Steps, you should be able to connect and join your Friends
8. The Host must use the Tiny Great Pot to create a Session. At that Point, the other players can join using the Effigy of Meleina. You should spawn in at a Point nearby the Host. Any Player can leave at any time using the Separating Mist - If the Host uses this Item, the Session will be disbanded and all Players will disconnect.
