Immaterial and Missing Power/BGM Changer

bgmpak is a program that allows the user to replace any background music in IaMP with a WAV file of choice. Wave file needs to be in 44.100kHz, 16bit, stereo format.

Instruction

1. Place bgmpak.exe, bgm.txt and the music file you're going to replace with in IaMP directory.

2-1. Open bgm.txt with a text editor and write the name of the music file you want to replace with after =. e.g. 00a=example.wav. Make sure there's no space in the file name.

2-2. To set the loop condition, do as the following: FileName:LoopStart,LoopEnd. Put loop start and end in bytes. e.g. 00a=example.wav:0x0010,0x00FF. Use a number starting with 0 if you're using octal (like 0564) and use a number starting with 0x if using hexadecimal (like 0x564). If the loop condition is not specified, the music will play normally without restarting.

3. Run bgmpak.exe. NOTE: Running bgmpak.exe permanently and irreversibly modifies your th075bgm.dat file. You might want to make a backup of th075bgm.dat just in case.
