Hello,
I'm working on a tool to make customs for Guitar Hero III on PC. So far there's only been one tool to do it, and it's a bit outdated at this point.
Until now, I'm still relying on the old tool to do half of the work, namely creating the audio. From what I know, it's an FSB3 file Version 3.1, with 4-7 MP3 files inside (though no header information for each part, as that is all in the FSB header). I know there are tools that can create them for me, including fsbext, but I'm interested in knowing how to make them myself. Are there any resources out there that describe how the audio is compiled, compressed, and encrypted in Guitar Hero III's FSB files?
