Preparations

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

  • Get your songs ready.

    • All songs in WAV-format

    • "Intro" song 1:39 length

    • Mid game song 4:04 length

    • Late game song 3:50 length

  • [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 BNK gui.exe!"

  • Solution: Firstly, before importing ur WAV-files setup the source settings first! Then re-convert the WAV-files again to WEM until their file sizes are smaller compared to their WAV-files. If they are pretty much same as WAVs, then the conversion have failed/bugged.
