[I put here the timestamps of each steps from the video, if you want to jump to a specific part.]

  • Get your songs x1-3 ready.
    • All songs in WAV-format
    • “Intro” song 1:39 length
    • Mid game song 4:04
    • Late game song 3:50
  • [0:21] Download needed programs + mod files including ZIP-file.
  • [1:55] Install Wwise (latest or 2016 version).

Let’s get to work!

  • [0:58] Open BNK Extract (BNK gui.exe) and insert the asked files to the program.
  • [2:18] Launch Wwise from the launcher and create the conversion project.
  • [5:04] Back to BNK Extract where the REAL magic happens by replacing the default/previous songs WEM-data and finally creating your treasure: The WPK-file!

Creating The Mod Itself Finally!

[6:31] Open LCS-Manager at last and make your dream BGM mod a reality!

Known Issues

“I can’t hear anything when I try in-game, but it works in GUI.exe!”

  • Solution: Just re-convert the WAV-files again to WEM until their file sizes are like under 10 Mb each. If they are pretty much same as WAVs, then the conversion have failed/bugged.
