1. Using anything from the official SDK is illegal.
2. If you do the effore to replace the files from the temp audio directory why would you use re-encodes from PSP? Just replace them with real PCM audio from the OST Disc, I did that on Kingdom: Hearts Birth By Sleep which gives a 200% boost in audio quality and clarity.
3. Using Flacs instead of WAVS it's indeed a good idea, i thought of it too BUT it draws quite alot of resources to decode which is not a good idea for PCs that are just barely being able to play some games. On top of that, straight decode from OMA to FLAC is impossible, you need to inject a third process/encoder from OMA to WAV to Flac which would add a huge lag.
4. Not every game uses that version of encoded ATRACs (KH:BBS example) and the current way of decoding (via soundstage) is more universal than the one on the SDK.
What you can do is write a decoder using stuff/source from the most late SDK of PS3 that leaked trying to get rid all of the Sony-copyrighted code and put it internaly on JPCSP which would defeat the reason to decode first to wav and then playback.
