Music editing

First of all: enable file extensions systemwise. This ensures you will see filename.mp3 instead of just filename. This often causes trouble when people see filename.bik, while in reality it's something like '''filename.bik.mp3```.

Audio conversion steps

To convert common MP3 or WAV files to in-game BIK files, perform the following steps:

• Download and install RAD Game Tools/RAD Video Tools: https://www.radgametools.com/bnkdown.htm
• Select your preferred source audio file (check supported formats)
• Press "Bink It!" button
• Change the output path if needed.
• Set "File Format" to Bink 1 (.bik extension)
• Check "Compress audio"
• Set Compress Level = 0
• Set Rate = 44100
• Set Sound Format = 16-bit/stereo
• Press "Bink" button and wait.

You can reduce the file size by lowering the sampling rate. BINK version used in THPS2 doesn't seem to work with compressed audio unfortunately.

Playlist editing

THPS2 folder should contain another folder called music. There is a set of dat files inside. Those files are basically renamed .bik files. If the folder is missing, just create one manually.

• Move your converted file to the music folder.
• Add a new song entry to the database using sql_music_import https://github.com/DCxDemo/THPS2-Cumulative-Patch/tree/main/th2patcheditmusic
• It's actually not required to rename to .dat, you can keep .bik extension, just make sure you put proper file name on the CSV list.
