It's nice tool.. but i dont think its necessary.
U can decompile them easily with the given tools from Virtuos Tool.
Make sure u copy the lua file u want to decompile, from data035 folder to your elsword folder. JUST COPY~
For Example
open "cmd.exe"
Put in the Path to your Elsword Folder with ' cd '
ex:
cd C:\Programme\Gameforge4D\Elsword_De
Then type this (replace my .lua file with the one u want to decompile) and give the name for the .lua.dec File, like this
ex:
EWCryptTool.exe -d Dungeon_Velder_Hope_Bridge_Expert.lua Test.lua.dec
Now the Crypttool will create a "Test.lua.dec" in your folder
Now we're going to decompile the decrypt File, type this
Java -jar unluac.jar Test.lua.dec
U will see the Script in the cmd window , but we have to save it ,so type this
Java -jar unluac.jar Test.lua.dec > Dungeon_Velder_Hope_Bridge_Expert.lua
Now there will be a decompiled "Dungeon_Velder_Hope_Bridge_Expert.lua" in ur folder.
Now u can open the .lua file with Notepad or smth like this
