How to Get BepInEx Mods Working in My Time at Sandrock on Steam Deck

I had written up a guide to getting mods up and running on Deck on Reddit, but decided to bring it here in case more people wanted to get them working on their Steam Deck.

Let’s get this working

• First thing first, everything will be done in Desktop Mode. To get there, press the STEAM key, go down to “Power”, and select “Switch to Desktop”.
• Open up your web browser and head on over to the BepInEx Github and download the “BepInEx_x64_5.4.22.0.zip” file
• Back on Steam, navigate to My Time at Sandrock, and click on the gear icon on the right side. Manage > Browse Local Files
• This is where you need to extract the zip file you just downloaded. Everything goes into the root folder (where the Sandrock.exe is located)
  —If for whatever reason you need to manually find the folder:
  Internal Storage: “/Home/.steam/steam/steamapps/common/My Time at Sandrock/”
  SD Card: “/run/media/mmcblk0p1/steamapps/common/My Time at Sandrock/”
• Be absolutely sure you extract the the contents where the game’s exe is. If “winhttp.dll” and “doorstop_config.ini” aren’t in the same folder as “Sandrock.exe”, it won’t work.
• Back on Steam, click the gear icon again, and select “Properties”
• Under “General”, scroll down till you see “Launch Options” and input:
  WINEDLLOVERRIDES=”winhttp=n,b” %command%
• Exit “Properties” and run the game once.
• If everything is working, you should see some files generated under “BepInEx/config”
• Once that is done, you’re ready to head on over to the Nexus and install some mods
• Most mods go into “BepInEx/plugins” but please read the mod descriptions for their install instructions. Most mod authors will have instructions on how to install their mods in their descriptions or on a sticky post in the comments.

Some extra tips:
DevConsole: You will need to bind F1 to one of your keys (I use a back button) if you plan on playing with the deck’s controls to use the mod.
Your Time at Sandrock: Similar situation with F4, but you can also get to the mod menu from the “Escape Menu” in game.
