Hacking Wii FSB files?

[Knuxfan24]

I've recently been poking around inside the ISO of Metroid Prime 3, & I found all the music files, but rather than being in the BRSTM format I was used to. They're in the FSB format. Is there anyway to compile an audio file (MP3, FLAC, etc) into the FSB format & have it be readable by the Wii?

What do you want to do, change the music of Metroid Prime 3?

Ah, the good old Metroid Prime FSB days. Google should give you the answers you seek on this one.

Yes indeed. I've being able to swap the tracks that are in the game already. But making new FSB files is something I can't get my head around.

Apparently FSB files are "FMOD Sound Bank" files, and can be made with some of the tools available here: http://fmod.org/fmod-downloads.html

Hello everyone. I'm reviving this thread because I'm in the exact same situation: trying to modify the music for Metroid Prime 3 (Wii) and I need to create compatible FSB3 files with the Nintendo DSP 4-bit ADPCM format and its specific interleave of 0x8f00 bytes.

I followed the path suggested here, but the link to FMOD (fmod.org/fmod-downloads.html) is dead. I have done extensive research and tried absolutely everything without success:

1. Jackoalan's Audacity fork: Generates FSB3, but they are corrupt.
2. fsbankcl / fsbankexcl (from recent FMOD downloads): Only generate FSB4 with IMA ADPCM. I patched the game's main.dol to change 'FSB3' to 'FSB4', but the game freezes when loading the audio. The issue is codec and header incompatibility.
3. fsbext -r: I can extract and rebuild an FSB, but the audio comes out with severe background noise. The problem is that fsbext does not correctly regenerate the ADPCM coefficients in the header of the intermediate .genh file, which is crucial for Nintendo DSP.
4. Compiling genh.exe from vgmstream: It is not a standalone tool; its source code depends on the project's internal libraries and fails to compile in isolation.

Research in old forum threads: In Metroid Prime Trilogy sound research threads (like "Metroid Prime Trilogy - Sound Research & Tools"), I have repeatedly seen mention of a specialized community tool called mp3_fsb_rebuilder (or similar names like MP3_FSB_Tool). From the comments, it seems to be a custom-made script or program that handles exactly the 0x8f00 interleave and the Nintendo DSP format for this game, which is where all general-purpose tools fail. Unfortunately, the download links in those threads are usually broken or inaccessible.

My concrete request:
Could someone who has successfully modified the audio for Metroid Prime 3 please be kind enough to share or re-upload that mp3_fsb_rebuilder tool? Or, failing that, the specific version of the FMOD tools (FMOD Ex/Designer) that were originally used and can generate FSB3 with the correct DSP codec.

A download link, an attachment here, or precise instructions would be my salvation after weeks of attempts. Thank you very much in advance for any help you can provide!
