In the licence file for the DoD game, a version number was changed from 0.4.0 to 0.5.0.
Reason unknown.
Then you're using the wrong original. There's a 0.5.0 that I compared against and posted about above. I was first working off of 0.3.1 and it was already pretty close, so you probably don't need to worry about grabbing 0.5.0 at this point. (Note that the .exe installer works with Wine, if you do want to go down that route and check my work.)
regarding the last of the words/phrases, I was wondering if they might be part of a dark wallet wallet recovery seed, but since there wasn't a clear way to order them, brute forcing that seemed overly tedious.
Played the game, read the docs. Can't seem to make anything stick
Heh, I've been avoiding actually playing that game, maybe there's a phrase or something in there.
EDIT: It's not possible for the first half of Space.mp4 to /be/ anything because it is an exact copy of the source posted on the 25th feb 2014 (the same date as the album).
Probably just padding but its contents /may/ be something for the password. I've ran so many double sha's on everything about that file. No joy.
Yeah, ugh. Welcome!
You said the same QR-code were in all of them. Is there still one audio file you havn't solved?
The 16_kaboom.wav file has an audio fragment that might be a clue. Either speed it up or change the sampling rate. Sounds like a naggingly familiar chopped out piece of an old 8 bit game.
