Dance Revolution 2010 (PS3) GWB/GSB files

[madkat]

Hello friends, I was messing with this kind of files, they have the sound data for announcers and menu, I only need to extract the sounds to convert them to a normal format like mp3.

I have checked the both extension files with an Hex editor, the GSB file looks like an index of files, it has the original names of files, and the GSB file has the names of the files too, they are seem to be in a MSF extension as far I can see in the hex editor. I've checked the file, and seems to be "easy" to extract them, but I don't know how to do it. I don't need to repack them only, extract to convert to mp3 or a common audio format.

Following are two samples of the files If someone could help me.

The MSFC files can be converted in ATRAC, AlphaTwentyThree knows how to do that:
