Psarc from Kingdom Hearts HD PS4

[onelight]

Hello,

I recently dump my disc of Kingdom Hearts HD JP on ps4, and try extrac files.
I got some psarc files, after tried every tool and script, only this bms script from https://zenhax.com/viewtopic.php?f=9&t=7679 working
But the extraced files don't have proper filenames or extensions.

Here are some samples : http://www.mediafire.com/file/02245j7t6 ... psarc/file

It looks like files have hashes as names. And the file with the name "00000000000000000000000000000000" contains the proper names for all of the files.

The script is perfect but this game uses an md5 hash calculated on the upper-case filename which is not like the usual "as-is" filename.
Maybe it's the flag 0x01 but I don't have enough samples to prove it so, in doubt, I opted for 3 sets of hashes: original name, uppercase, lowercase
Script 0.4.1:
