Help ripping Kingdom Hearts Birth by Sleep?

All of the links for a 320kbps gamerip are dead so I figured I should try ripping it myself and I’ve already hit a wall. There’s 5 .dat files and I’m sure that the music is stored in of those, but I can’t do anything with them at all. Does anyone know how to extract them?

Thanks!

FYI, My goal is to get the 3 missing tracks that are not on the OST: Vim and Vigor, The Encounter, and Working Together.

EDIT: I found a program called ‘AA3Get’ that grabs all of the music files from a .dat file, all I need to do is just find the damn songs I’m looking for.
