Yet another at3+ encoder/decoder
Thanks to serio.
It's inside the PGD file of Fate/Extra CCC (NPJH50505)

PLEASE NOTE THAT WE DO NOT SUPPORT OR ENDORSE PIRACY. SO DON'T ASK FOR UPLOAD OR ANY KIND OF REDISTRIBUTION. IF YOU WANT THIS GAME, GO BUY IT YOURSELF.

If you have the ISO file , use JPCSP or other tools to decrypt the PGD then unpack the cpk, namely the decrypted PGD file, and you should find "at3tool.exe" under the sound/bgm/decode/ folder.

I guess Hykem will be the first interested on this... And the people of PPSSPP.

Hopefully this year JPCSP will not need a third party tool/program to play all sounds.

Could you test r3075 and place at3tool.exe under lib/windows-x86 or lib/windows-amd64? I've added basic support for this tool, but could not test it.

Always include a complete log file at INFO level in your reports. Thanks! How to post a log

gid15, 3075 works with this tool but not will as some files are not decoded and there's a high pitch noise when mono WAVs are being played.
tested with Fate/Extra CCC.
BTW, have you read http://www.emunewz.net/forum/showthread.php?tid=129065 already ?

RE: Yet another at3+ encoder/decoder
Wait,how did you transform the decrypted pgd into a cpk file?I'm trying to see the models in a game but don't know how to get the cpk file

Am I the only one with this cool sig?

if you use jpcsp, "PGDfile.raw.decrypted" is the one you wantWink

RE: Yet another at3+ encoder/decoder
So you just change the file extension to cpk and then unpack?

gid15,test with r3076,the bgm will disappear
DecodeAudio.bat should be modified to this
Code:
lib\windows-amd64\at3tool.exe -d -repeat 1 %3 %2

plus some stereo bgms seems not decodable with this tool but decodable with atrac3plus2wav.exe (oma file, namely %1)
tested with F/E CCC

Yeah,modify DecodeAudio.bat to this
Code:
:at3tool
lib\windows-amd64\at3tool.exe -d -repeat 1 %3 %2
IF NOT EXIST "%2" ( lib\windows-amd64\HIMDRender.exe -e -i %1 -o %2 )
:end
I think can solve.Tongue
