¶ Special K Injection Frontend (SKIF)
Special K Injection Frontend (SKIF) is the new frontend that began development in late 2019 and is used to manage Special K across all games. It is bundled within the Special K installer and is updated alongside Special K.
Features:
- Lists Epic, GOG, Steam, and Xbox games.
- Supports custom games to easily inject Special K in games from other platforms.
- Automatically starts and stops the injection service when launching a game through the app.
- Features high resolution game covers, as well as the option to set custom cover for games.
- Features quick links to usable resources such as PGGamingWiki, SteamGridDB for custom covers, and SteamDB/GOG Database for technical data on games on said platforms.
- Can act in a launcher capacity for Steam games using the
SKIF %COMMAND%launch option to quickly inject Special K into Steam games even when launched through the Steam client itself.
¶ Command line arguments
| Argument | What it does |
|---|---|
<empty> |
Launches SKIF. |
Start |
Launches SKIF and starts an instance of the injection service. |
Temp |
Used with Start to indicate the injection service should auto-stop after a successful injection. |
Stop |
Stops running instances of the injection service. Can also be used to attempt to force-eject leftover injections of Special K. |
Quit |
Closes running instances of SKIF. |
Minimize |
Launches SKIF minimized or minimizes any running instances of SKIF, to the taskbar or notification area depending on configuration. |
"<path>.exe" |
Uses SKIF as a launcher to start the injection service, launch another application, and then stop the service. Any arguments specified after the path is proxied to the launched application. Called through SKIF %COMMAND% from within the Steam client. |
AddGame="<path>" |
Experimental! Adds the specified application to the library of SKIF as a custom game. |
RestartDisplDrv |
Requires elevation! Restarts the display driver (useful as this can sometimes fix MPOs). |
¶ Plugins (load external DLLs)
Special K supports making use of various third-party utilities as well. These are typically stored in Special K\ThirdParty\ or in the game folder for local installs.
¶ dgVoodoo 2
Special K can automatically make use of dgVoodoo 2 to extend its supported render APIs to include Direct3D 2-8 and DirectDraw.
¶ ReShade
Special K can load ReShade through its plugin system, which often have a higher compatibility than loading ReShade through alternative methods.
¶ Custom plugin
Please note that compatibility with every single third-party DLL mod can not be guaranteed. This might work, or it might not.
Users can also specify a custom plugin that Special K will attempt to load alongside itself.
-
Install the local wrapper of Special K for the game to ensure maximum compatibility.
-
Open the game-specific config.
-
Add the following to the bottom of the file:
[Import.NameOfPlugin] Architecture=Win32/x64 (should match the DLL file and the game itself) Role=ThirdParty When=Early/PlugIn/Lazy Blacklist= Filename=<Relative or absolute path to mod file>Example using ReShade and a 64-bit game:
[Import.ReShade64] Architecture=x64 Role=ThirdParty When=PlugIn Blacklist= Filename=C:\Program Files\Special K\PlugIns\ThirdParty\ReShade\ReShade64.dll -
Launch the game and see if the third-party mod is loaded in. If it doesn’t load try changing the When property.
List of properties and their possible values:
| Property | Value | Description |
|---|---|---|
| Architecture | x64 Win32 |
Architecture of the external DLL to load (should match the game). |
| Role | ThirdParty | Third-party (non-Special K) DLL files. |
| Role | Unofficial | Only used for Kaldaien’s Custom ReShade package. |
| When | Early PlugIn Lazy Late Proxy |
Load time for the plugin, from Early (before Special K) -> PlugIn -> Lazy/Late. Loading before Special K (Early) means that any effects or changes made by the plugin will be applied to Special K as well. Proxy is used to proxy everything through another plug-in that wants to be one of the following DLL files: dxgi.dll, d3d11.dll, d3d9.dll, dinput8.dll |
| Blacklist | Filename(s) | Comma separated list of executable filenames for which the plugin should be ignored, e.g. Blacklist=Atelier_Ryza_Launcher.exe,Atelier_Ryza_Env.exe |
| Filename | Relative Path Absolute Path |
Path to the DLL file to load. v22.06.15 and newer also supports expanding environmental variables. |
¶ Extended hardware monitoring driver
Special K can make use of the common WinRing0x64.sys kernel driver to enable advanced CPU hardware monitoring capabilities in its CPU widget. This is redistributed through a separate installer from the main Special K/SKIF package, with the installer creating a driver service on the system called SK_WinRing0 that autostarts the driver alongside the system boot as this is required to allow unelevated games to make use of it.
¶ Security concerns
The package exposes the system to CVE-2020-14979 (details), a Local Privilege Escalation vulnerability that can be exploited by malicious third-party code running locally to elevate their privileges to that of a local administrator.
This is a consequence of the intended purpose of allowing advanced CPU hardware monitoring capabilities in regular games that typically run unelevated (not as an admin), and our dependency on the WinRing0_1_2_0 kernel driver. While Special K’s custom user-mode driver is cut-down significantly and only implements the relevant CPU sensor code, the kernel driver itself includes more advanced hardware capabilities beyond that, meaning third-party apps/tools that make use of their own user-mode driver can also make use of those capabilities as a result.
This is sadly nothing we can solve as it is outside of our financial capabilities to create a cut-down custom kernel driver implementing only the CPU sensor capabilities.
If you are a corporate/business user or IT administrator on a corporate device, do not under any circumstances install this driver!
For regular end-users, whether this is a concern for you or not is ultimately up to you. To be able to exploit the vulnerability, any malicious code would need to be executed locally and go undetected by the anti-virus suite of the system, and at that point most malware can already perform similar local privilege escalations easily through alternate methods, such as through e.g. a simple UAC auto-elevation bypass.
¶ Playnite extension: Special K Helper
The user darklinkpower have created an extension for Playnite called Special K Helper that allows using and managing Special K for games through the Playnite library. The extension can be installed from the addons browser within Playnite, or through this Playnite link.
¶ Spodi’s Scripts
¶ Special K Starter Script (SKSS)
SKSS is a powershell script written by Spodi to start and stop Global Injection alongside an Application.
It can be used to launch a portable installation of Special K, allowing you to run Global Injection from custom paths and with different versions.
SKSS also provides the option to start the service with Administrator privileges, even with an unelevated instance already running.
This can be useful when you want to run a specific version of Special K for a game, without changing the version used by SKIF.
Download: Spodi’s Repository on Github (SKSS).
¶ Special K Local Updater (SKLU)
SKLU is a powershell script to update Local Injections present on your system.
This script scans all game folders known by SKIF and gives the option to replace any local Special K DLLs found with the ones in Special Ks default install location.
SKLU is a collaborative effort between Spodi and Wall_SoGB.
Download: Spodi’s Repository on Github (SKLU).
¶ Misc tools
The following are miscellaneous tools related to Special K that might be of use for some.
¶ Special K Install Manager (SKIM)
This version has not been updated further than to v0.10.2.1 dated June 20, 2019 and is no longer fully functioning as of 2021 due to changes in Steam’s library format.
Special K Install Manager (SKIM) is the old frontend used and distributed before the Steam version of Special K was introduced. SKIM supports toggling global injection, automated install of some game-specific mods, as well as managing additional modules for some of the game-specific mods – a function not yet seen in SKIF.
While SKIM can still be used to install and manage older game-specific Special K-based mods such as TBFix, FAR, etc, it otherwise sees no continued development or maintenance.
- Download and run the following installer;
¶ Disable autostart with Windows
SKIM makes use of a shortcut in shell:startup to achieve autostarting functionality. This task can be disabled in various ways:
- Run SKIM and right-click on its icon in the notification area of Windows besides the system clock. Untick the
Start With Windowsoption. - Open the Run window of Windows by utilizing the ⊞ Win+R hotkey. Type in
shell:startupand click on OK. In the folder that opens, remove theSKIM64shortcut.
¶ SK_UninstallScript
This script is outdated as of 2023 as it have not been updated to reflect Special K’s modern install paths or components.
SK_UninstallScript is a basic PowerShell based uninstall script that automatically terminates the global injector service and removes autostart entries for both SKIF and the legacy SKIM based injection frontend.
This can be used as a helper tool for troubleshooting purposes.

During the development of Special K on Steam, very few point releases saw availability outside of the platform. ↩︎
The original Special K GitHub repository received multiple fradulent malware reports back in May 2017 which caused GitHub to remove it, and as a result older versions of Special K was lost. ↩︎
