Contacted the guy that did the tool, and he said that she will change the tool to have user interface, instead of use command line bat files, since work with it along using translator++ is a bit messy for users.
For decompile use the following with ZADD.DAT file: SW_Tools.exe -decompile_dat DMD_ZADD.DAT . (backup that .dat file)
For extract text from did_mes (text container), use: SW_Tools.exe -decompile_text DMD_ZADD\DID_MES_20_DAT DMD_ZADD\texts_folder (also backup that did_mes file outside of that folder)
For compile text after editing, use: SW_Tools.exe -compile_text DMD_ZADD\texts_folder DMD_ZADD\DID_MES_20_DAT
For compile dat again: SW_Tools.exe -compile_dat DMD_ZADD DMD_ZADD.DAT
Also be aware when editing that this game text only works with japanese type text, so to use english, without using translator++ de/compile, it needs to be full-width romaji text when you write on files using notepad++ or whatever text editor.

Tested and works properly. Text extraction makes the name of export folder a bit messy but just rename it and should be ok
