@DenisColli: It's all explained in the "Readme.txt".
When you "Save Steam Mod" (generating spreadsheets and assets), you'll get many of the files of AF but not all of them.
All the other files, except one, are to be picked directly from AF's mod folder (not the source); for instance, the file "DictionaryPatch.txt" was written by hand so you can consider it as part of the source.
The last file that is neither generated by HW nor created "by hand" is the "Memoria.Scripts.dll". The source code of that file consists of the .cs files in the folder "Source/Battle" of AF. Check the documentation of Memoria to see how to generate the DLL from these files (basically, you need to replace the folder "StreamingAssets\Scripts\Sources\Battle" by the one from AF, then run "StreamingAssets\Scripts\Compiler\Memoria.Compiler.exe": if everything goes fine, the program should tell you so and the "Memoria.Scripts.dll" should be (re)generated in the parent folder).
