There's a couple of tools on here that might be able to help but I have no idea how to compile either of them.

So there's some .hca files that I have that are encrypted and someone online has the decryption key (basically the Sonic Runners thread from earlier). It looks like you guys have been able to decrypt .hca files and I'm curious as to what you guys are using.

and also I'm having a difficult time getting hcatools to compile. :S

EDIT: nvm, didn't know HCA_decoder was able to utilize a key through the batch file, worked like a charm, now to see if a certain event song is within the archives I found

Does anybody happen to have an old version of the ADX2LE SDK? As old as possible is good, but I think something in the version 1xx or lower range will do.

I was able to find links to some of the old ones:

Sorry if this seems a bit off topic , since i haven't found an answer for this particular thing.

Can we convert wav/mp3 to HCA files?

i know VGMtoolbox extracts HCA files nicely to convert them to wav , but i actually want to do the opposite.

Is there a way to do that?

With the official encoder provided in the CRI ADX2 SDKs.

Yo guys,

I recently got my hands on the new Tekken Mobile game for iOS/Android, and the music in that is converted in AWB/ACB format. I tried to convert it to HCA and then to WAV, but it's encrypted. I think the key is probably in the ACB file(s) but I don't have the know-how to find it. If anyone here knows how to do it, it'd be appreciated if they could convert the files or talk me through how to do it myself!

here's the awb/acb files within the directory. Thanks!

@ssh - That's a fun "key" ^^
@Shirdel - I allowed myself to upload the set. If you don't know how to create the .hcakey-file you can soon find the set on
