This is a newer Extractor and is much faster than the old one.
Instruction:
-Make sure there is els_KOM.exe and any .kom files you want to extract was at the same directory. (Image above)
-Run els_KOM.exe
-Drag in .kom file into the windows to extract the files. It'll create a file folder for you.
-Drag in folder instead if you want to repack into .kom
Note: Do not do anything when it's under 忙碌 (working in progress) status.
how to use in game:
When you start the game, before x2 start, but after the check update window, you need to replace the corresponding .kom file in the short time that happens. Make backups.
so uh, have fun...
