Crisis Core: Final Fantasy VII - ULUS10336

[Agent69]

Just name the files as something like this, for example:
Atrac-[filesize]-[number].decat3
With "number" going from 0 up to the number of atrac files present in the game, just like a playlist. We'll then make JPCSP recognize these files and play them instead.

Maybe no need extra nomenclature: just change emu src, to use another valuves to identification sound data, like
String generateID(int fileSize, int Last_4_bytes_in_At3_file), and check: if (file not found in atrac folder) send to psp for decoding.
Extract sound data possible from any game, but will not know the address and "number", and calculate the hash for each file - the loss of speed.
