This is a repository for the linux sources for CBSWin, found there : http://dmweb.free.fr/community/clones/chaos-strikes-back-for-windows-and-linux-raspbian-macos-x-pocket-pc/

PAUL R STEVENS doesn't want to maintain them for now.
The latest sources from Paul are here https://www.dianneandpaul.net/CSBwin/CSBwin_SRC_20230608.7z
but they have been merged into this git quite some time ago already.

You can compile a windows version either 32 or 64 bits from this source, or a linux version. Just
select the right target at the top of the makefile. For now the only thing required is sdl2.
Since I crosscompile the windows binary, the makefile uses a prefix for pkg-config, which doesn't
exist in mingw apprently, so you might need to using pkg-config without prefix if using a native
mingw environment.

You'll find a summary of the changes in this forum thread : (along with links to
the binary version, containing dungeon.dat and graphics.dat for the original
dungeon master).

You should also get the new sounds from the binary packages in the forum
thread, they are not included in the git repository. Same thing for the font,
the default font is Vera.ttf which is freely available from the web, and is
included only in the binary packages. While you are at it, also grab lsb.bmp
which is used for the application icon for desktop environments which know how
to handle this. All these files are not mandatory, the program can run without
them, but it's better with them. In the most recent version I also added 2 more
fonts for the truetype interface, diogenes.ttf and OldeEnglish.ttf, both can be
found on dafont.

Sometimes you'll be able to find more info about these dungeons in the forum.
DMCoE thread: https://www.dungeon-master.com/forum/viewtopic.php?t=31647
(don't let the 1st post fool you, DMCoE is a major dungeon, maybe the most
ambitious dungeon ever made for dungeon master. It's not for everyone though,
it's very hard, and it changes a lot of things in the way to play the game).
There is a link to the guide for this dungeon in the 1st page of the thread.
Very detailled guide.
It's based on conflux which is there http://dianneandpaul.net/CSBwin/Games/Conflux_Description.html
but since DMCoE is supposed to be an improved version of conflux...
I'd say a few things are easier in conflux3, especially at the beginning of the
game. There is a huge wiki about conflux here: https://dmwiki.atomas.com/wiki/Conflux
