I already used UMDGen and QuickBMS to extract some files:

Diva2Data.cpk 402MB
Diva2Script.cpk 8MB
Diva2Sound.cpk 581MB

I believe the third one is the right file*, since the files I extracted have names that match the PVs I can watch in the game. The thing is that the files have extension ".aix" I've been searching around in google but with no luck. I only found about ".pmf" files, but there is only one available in the game, and it must be the intro.

Is there a way for me to extract the videos so that I can encode them? Am I using the wrong method?


*The folder first seems to have pictures (loading..., unlockable pics, etc.) and some data needed for the game, so I'm guessing that's not it. The second one is too small to have any music videos.
