SmokeAPI is a DLC unlocker for the games that are legitimately owned in your Steam account. It attempts to spoof games that use Steamworks SDK into believing that you own desired DLCs. However, SmokeAPI does not modify the rest of the Steamworks SDK, hence features like multiplayer, achievements, etc. remain fully functional.

In this installation mode, SmokeAPI is loaded into the Steam process, which makes it able to affect all Steam games.

1. Download the latest Koaloader release zip from Koaloader Releases.

2. From Koaloader archive unpack version.dll from version-32, and place it in the Steam directory^[1].

3. In the Steam directory^[1] create the following Koaloader configuration file:

   Koaloader.config.json

   {
     "auto_load": false,
     "targets": [
       "Steam.exe"
     ],
     "modules": [
       {
         "path": "SmokeAPI.dll",
         "required": true
       }
     ]
   }

4. Download the latest SmokeAPI release zip from SmokeAPI Releases.

5. From SmokeAPI archive unpack steam_api.dll, rename it to SmokeAPI.dll, and place it in the Steam directory^[1].

In this installation mode, SmokeAPI is loaded into a game process, which limits it to that particular game only. This mode itself supports 2 modes: hook mode and proxy mode. Try installing the unlocker in hook mode first. If it doesn’t work, try installing it in proxy mode.

🪝 Hook mode

🔀 Proxy mode

$version

A technical field reserved for use by tools like GUI config editors. Do not modify this value.

Type	Integer
Default	2

extra_dlcs

See How SmokeAPI works in games with large number of DLCs to understand the use case for this option.

Possible values	An object with key-value pairs, where the key corresponds to the app ID, and value to the object that contains DLC IDs. The format is the same as in the aforementioned GitHub config.
Type	Object
Default	{}

store_config

Store mode only. An object that specifies offsets required for store mode operation. It will override the config fetched from remote source or local cache. Do not modify this value unless you know what you are doing.

Type	Object
Default	See online config

Some games that have a large number of DLCs begin ownership verification by querying the Steamworks API for a list of all available DLCs. Once the game receives the list, it will go over each item and check the ownership. The issue arises from the fact that response from Steamworks SDK may max out at 64, depending on how much unowned DLCs the user has. To alleviate this issue, SmokeAPI will make a web request to Steam API for a full list of DLCs, which works well most of the time. Unfortunately, even the web API does not solve all of our problems, because it will only return DLCs that are available in Steam store. This means that DLCs without a dedicated store offer, such as pre-order DLCs will be left out. That’s where the extra_dlcs config option comes into play. You can specify those missing DLC IDs there, and SmokeAPI will make them available to the game. However, this introduces the need for manual configuration, which goes against the ideals of this project. To remedy this issue SmokeAPI will also fetch a manually maintained list of extra DLCs stored in a GitHub repository. The purpose of this document is to contain all the DLC IDs that are lacking a Steam store page. This enables SmokeAPI to unlock all DLCs without any config file at all. Feel free to report in the SmokeAPI forum topic games that have more than 64 DLCs, and have DLCs without a dedicated store page. They will be added to the list of missing DLC IDs to facilitate config-less operation.
