Tales of the Heroes Twin Brave(PSP) .AT3 help

[kaimuangel]

I've been adamantly trying to get access to the music files in the game. So far I've used Namco BDI Tool to extract a few thousand .at3 files,
I'm trying to play them with vgmstream but they don't work, I need to know what's wrong with this these AT3 files I extracted.



Thanks in advance.
