- Shin Star, email me at halleyscometsoftware at hotmail and I'll send you ftp info.
I'm sorry I haven't done anything with this in a few days...
On the other hand you might not want to bother, I'm downloading the whole God Hand ISO now and I only have about 100 MB left, should be done before you can upload the AFS.

- So you have a disk space problem too huh? lol it's always fun to try to see what you can get rid of or keep..
But yeah no need to apologize. I'm just glad to hear you're willing to try to get this to work, and that's good enough for me :D.

- Alrighty, took a few days longer to get God Hand than I thought.
The consensus method worked a little better with all the files to draw from, but still sounded like poor radio reception.
Then! I found the .sfd files for the english and japanese credits. They have unencrypted ADX audio, which almost exactly matched the standalone, but encrypted output ADXs. I was able to XOR the scales together to get approximately the correct encryption stream. From simple inspection is was apparent that the period of the function was only 8192, so I was able to do another consensus pass to determine exactly what the stream is. I then plugged that into the brute force program I'd put together earlier to find the parameters for the decryption function. It turns out to be CRI's in-house encryption after all.
The upshot of which is degod, now on the in_cube page, which will decrypt the ADX files in God Hand. I tested it with Okami as well, seems to work.

- Wow this is awesome. I wasn't expecting it to get cracked that soon. Thank you so much! I'm testing them out right now and so far they seem to sound real good. I haven't touched the game in awhile, but I will go back to it soon. If I notice anything, I'll let you know. Again, thanks for your time in this. I'll rip these into mp3s or something later I guess and make a "complete OST" :)
Glad to know my hunch was right about the adx format too...at least I figured something out haha.

- Oh man, I almost forgot about this. I've been a little busy lately and I see you were too hcs! I decrypted all of the files just now and they all play flawlessly with in_cube. This is awesome! I'm gonna go ahead and make a proper "album" out of these like Shin right now, except in FLAC. =D
Thanks a lot for doing this hcs!
And to Shin, it was just a pure stroke of luck that I managed to find a forum where someone was interested in ripping the music God Hand from too. I saw the post you made was only a few days old so I decided to follow up on it.

- Glad to help out. As payment you must bring me any other files you cannot play.
God Hand BGM, decrypted.
Okami, decrypted. I tried to separate out the BGM from the sound effects.

- Well eightfold glad you got lucky and found my post. This would have also never been possible without you :D
Alright files, I'll check those out too!
wtf typo. fixed.

- Wow, thanks so much for decrypting these files (God Hand in particular)!
Unfortunately degod won't work on other games with encrypted ADXs. I've tested Samurai Champloo, Killer7, Blood+ (all them by Grasshopper Manufacture) and Raiden3 and they won't decrypt correctly. I'll see if I can find more of these ADXs.
Here are a few samples if you want to check them: http://www.sendspace.com/file/cwgxkk
I've included IRXs just in case (seems all these games have slightly different revisions of the driver, even God Hand and Okami).
- by hcs at 5:33 PM EDT on October 21, 2007
- Thanks for all the samples.
I think these all almost certainly use the same algorithm, just a different key. Finding that key (more likely, those keys) will be troublesome, but away I go...

- HCS, thank you so much for making the Okami ADX available!
If anyone is interested, here are some Chip Tune versions of some of the Okami songs:
01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 sheet music
Some of you may already know about these.
