Hello, i have problems to decrypt some ".nob" files from one game of xbox360, that game its "Naruto Ultimate Ninja Storm 2", the collectors edition come with 14 track of more than 36, and i want to decrypt that ".nob" files, but i cant, i can extract a xma file but i cant ear it or edit it, so.. I need help, Can anyone help me?, i used the "NUBExt_r11beta" to try extract the xma file, but i dont know if it works because i cant do nothing with the xma file... i attach the NUBExt_r11beta and 2 tracks, if anyone can decrypt it, please, show me how, i want the full ost :(

NUBExt_r11beta:

.Nub file:

Please, if anyone can.. Help me :(

the archive is not encrypted and the same seems valid for the xma file because its first 4 bytes contain the zeroes of the format.
I don't know that program anyway if the xma header has been created correctly I don't see problems, maybe try with towav or xmadecode.

I can't help more than this at the moment, so refer to the Audio section of the Xentax forum where there are people that work everyday with xma
