I'm a few weeks away from bothering one of the games' composers to see if he can provide some tracks for me to help complete my dirty rip. I had to manually loop each and every world theme by hand.
I'm just interested to see which gets done first, though I hope they both do.
Let me update here saying that i have not seen xma tracks in the game, i know what the xma strucutre looks like and the only tracks ive seen apart from raw pcm is WMV3 headers inside the no file extension files, seems it uses this format but i cannot figure out how to decode it.
