Yes, we have indeed been messing with it. I just finished sorting out the audio for disk 1, and once binary wakes up and codes a rebuild feature for the unnecessarily complicated tool to take apart this unnecessarily complicated ps1 game, we’ll have first half of the ps1 valkyrie profile undub done. I will record some material out of it once we manage to put the damn thing back together.
no, it was not unhackable, and yes, it’s stupidly complicated and overengineered for what it is. The sourcecode of the tool, which I like to call valcrypt will be released once we polish it a little. It currently has some minor issues with filetype identification, and it does not sort the contents (yet.)
