[Guide] Decode & Batch Copy PSP Audio / Video

[Kai3213]

In Persona 1 Portable, I had some issues with missing BGMs that replaced by some other. I did some research and now I know what's the problem. So after disabling JPCSP-s internal decoder option and manually decoding and renaming the game's *.at3 files, I got files that looks as follows:
"Atrac-0005F244-00204CF3-6C83643A.at3.wav"

Problem is that the emulator didn't recognize this filename format. What it wants is this format:
"Atrac-0005F244-08E29020.wav"

Now, I noticed that every internally decoded file's name had the same last hex values. In this case it's "08E29020". So I begun to rename every wav until I met the REAL problem. Now, I have 5 files with a name beginning with "Atrac-0005F244". If I want to use these files, I have to rename the last part to "08E29020". But 5 different file under the same name can't be possible.

Is there a way to use the "Atrac-********-********-********.at3.wav" format instead of the shorter one? Or there is some workaround so I can hear these "missing" BGMs?

In the case of Crisis Core, it recognized the longer format, or you had to rename to the shorter one too? I didn't get this part

I'm pretty sure that's what hyakki's renamer tool was created for. Link can be found on the first page
