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]].


Once complete, this engine would add support to more than fifty 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 of which they dream.

* The window-caption-setting in-game will be ignored, for the sake of concistency with ScummVM.
* Most VKey-combinations might still be missing (as they already were in WME Lite)
* 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.

* UTF8-support is not ported, which means only games with western charsets will work for now.
* Games that select language by moving .dcp-files around still need a bit more handling on detection/load adding support for those languages on a language-by-language basis.
* 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.

==Games with known issues:==
==Known issues:==
Certain games will work mostly fine with this engine, but can still be impossible to complete for various reasons, this is a list of games
that technically qualify but have issues that make them problematic or not completable:
 
Gameplay broken:
* J.U.L.I.A. (Full game) (julia) - Requires sprite-rotation for a puzzle.
 
Non-critical:
* East Side Story (eastside) - wants "framd.ttf"
 
==General known issues:==
