The tmp folder is inside your JPCSP main folder; don't confuse it with Windows Temp folder. Like this:
   

I guess you need enable Decode Audio With SonicStage under Media tag on JPCSP option's.
   

NOTE: Some users says that certain games need the option Extract Media Files to TMP folder in order to get the Atrac folder; however, i didn't enable that option and just with the 1st run on GOW Ghost Of Sparta it bring me the sound files on to the Atrac folder. (Are on .oma format)
