🎮 Function details

Server IP mode

The host supports three IP connection modes:

🔹 **IPv4 ONLY** - Only supports IPv4 client connections

🔹 **IPv6 ONLY** - Only supports IPv6 client connections

🔹 **Dual Protocol** - Supports both IPv4 and IPv6 client connections

Operation Guide

**Host Operation:**

  • When entering the archive, the currently used IP mode will be displayed in the lower left corner.
  • Press and hold the following keys to specify the IP mode when loading an archive:
  • `4` key: IPv4 mode only
  • `6` key: IPv6 mode only
  • Press and hold `4` and `6` simultaneously: dual protocol mode

**Client operation:**

  • The client will automatically select the appropriate IP mode based on the entered server address.

-Supports entering IP address and domain name address

  • No need for manual control by players, intelligent connection

💡 Usage suggestions

  • If SMAPI is installed, it doesn't matter which version you choose
  • There is no problem if both patches are installed (but this is not recommended)
  • By default, the server automatically selects the IP mode based on the protocols supported by the device

🎯 **Modernize the online experience of Stardew Valley! **

Install & use Install: SMAPI mod (Stardew Valley standard)

  1. Install SMAPI first (Stardew Valley's mod loader): download it from smapi.io, run 'install on Windows.bat' and pick your game folder.
  2. Unzip the archive from playbuff and find the folder that contains manifest.json — that folder is the mod.
  3. Copy that whole folder into Stardew Valley/Mods/.
  4. Launch the game through SMAPI (run StardewModdingAPI.exe or set it as the launch option). The console before the title screen lists each mod's load result.

Cheat-style tools may not need SMAPI — unzip and run them as the readme describes. Back up your save before editing it; SMAPI lists failed mods in its console.
