This engine is being added by the GSoC student [[User:somaen|somaen]] to ScummVM as part of the GSoC 2012.  Adding this engine would add support to more than fifty 2D games, would give the users a nice way to create games supported by ScummVM, and would bring to Dead::Code the portability they are dreaming of.
This engine was added by the [[Summer of Code|GSoC]] student [[User:somaen|somaen]] to ScummVM as part of the [[Summer of Code|Google Summer of Code]] in [[Summer of Code/GSoC2012#Wintermute integration in ScummVM|2012]]Its functionality was extended by the GSOC student [[User:t0by|t0by]] as part of the [[Summer of Code/GSoC2013#Improving Wintermute Engine|GSoC 2013]].
 
The 3D part of the engine was implemented by the GSOC student [[User:Fury|Fury]] as part of the [[Summer of Code/GSoC2020|GSoC 2020]].
 
Subengines for Wintermute forks were added by [[User:Lb_ii2|lb_ii]] to run games developed by [[Gingertips Game Studio]] and [[HeroCraft]].


==Games==
Once complete, this engine would add support for hundreds of 2D and 2.5D games, would give the users a nice way to create games supported by ScummVM, and would bring to Dead:Code the portability they are dreaming of.
 
==Features==
This port of the Wintermute Engine (WME) is based on WME Lite, which lacks some functionality originally found in WME: (from http://res.dead-code.org/doku.php/wmelite:start)
 
In addition, this port removes a few additional features that were never/rarely used.

==Additional limitations==
* Only .OGG and RAW-.WAV sounds are supported at this point
* TTF-fonts might behave a bit differently, owing to both the change to FreeType in WME Lite and the change in dpi in this port of WME.
* The window-caption-setting in-game will be ignored, for the sake of concistency with ScummVM.
* Since we don't use FreeImage, some games might use odd files that weren't expected when the image-decoders in ScummVM were written. One example here is interlaced-PNGs.
* Most games assume the availability of the Windows-fonts (particularly arial.ttf) at this point no fallback has been put in place for using FreeFonts as replacements, simply for lack of having them easily accessible to the engines at this point. So, at least arial.ttf should be put in either the game-folder or made available through the extras-folder for now, otherwise kGUIBigFont will be used as a replacement.
==Advanced engine-features==
At this point the engine implements the following "advanced engine features":
* RTL ("Return to Launcher") support
* Global options dialog support
* Listing savestates via command line or Launcher
* Loading savestates via command line or Launcher
* Deleting savestates via the Launcher and GMM
* Savestate metadata support
* Loading/Saving during run time
 
and NOT the following:
* Enhanced debug/error messages
 
==Detection==
Since Wintermute has authoring tools available, there will at any point in time be at least a few games that are works-in-progress, and as the authors of these games might want to test their games in ScummVM, the engine has to be able to detect arbitrary Wintermute-games, to this end the detector code in this engine will check any folder containing "data.dcp", and try to read "startup.settings" and "default.game" (or optionally any other .game-file defined in startup.settings), the Name/Caption fields in the .game-file will be used as gameid/title (prefixing the gameid with "wmefan-" to avoid confusion with any other WME game that might happen to have taken that id.
 
All known games should have their md5s and gameids properly added.
 
==Games targeted by the engine==
This engine potentially targets a very large amount of games:
