Encrypting ADX file back to original state??

Post by Guilhermex12 » Sun Sep 09, 2018 5:52 pm

Hello everyone, i've been trying to change Audio files on a mobile game called Dragon Ball Dokkan Battle, i have spent almost 2 weeks trying to change the music files in game. Details below:

It use .awb and .acb files, i sucefully extracted then using various tools like Sonic Audio Tools, AWB Unpacker/Repacker and VGToolsBox, got ADX files, they sound distorted and static, then i checked the ADX file on VGMstream (cuz it can play encrypted files on the fly) and have seen the file is a CRI ADX 4-bit ADPCM codec and is encrypted with Type 9 encryption.

So i used Degod (it contains Key codes for some games and Dokkan Battle was on the list), then i decrypted the .adx file using it and played it on Foobar without any distortions or statics.

The problem is, after trying to encrypt the file back and putting it on the game, it sound static and weird... why? The tool doesn't encrypt it correctly? How can i encrypt it again so the game can play the file like before?

Degod can decrypt ADXs file and has a option to encrypt too, but after doing this, when i try to play the new encrypted file on VGMstream, it doesn't play, doesn't show the Codec type of the file and nothing, just an error, but on Foobar the new encrypted file sounds static etc (meaning it's encrypted, right?) but after putting the new file on the game it sounds static as the file is wrong encrypted, why??

I also tried using VGAudio, a tool that can encode/decode ADX and it has a option to encrypt the file with Type 9, problem is a don't know the key code for encrypting it :/
If anyone want, i can upload the ADX file.

Basically what i'm trying to do is: Encrypt a custom music file so it can play normal on the game, if i put the file with no encryptions, it sounds weird and static, so yeah, this means the game is only going to play it OK if the file get encrypted, right?

Sorry for the long post but i tried giving every detail possible lol
And sorry for the bad english too :/ hope you guys can help me
