ARG Puzzle with 3.5 BTC Private Key Prize, Game Over

[S4VV4S]

FWIW, there's another QR code spectrographically hidden in 25_chirp.wav in the DoD game. It's the same code that arg found in Elements.jpg that led to Again.7z. This leads me to believe that the DoD branch is the red herring and the Space.mp4 branch is the endpoint.

I also think that. The question is what to do with that 2MB of data in our hands.

'Oτι δεν λύνεται, κόβεται....

But I wouldn't suggest you brute force anything.

I extracted another 7z file from the Space.mp4 by subtracting 100 from each byte of the last 2147129 bytes (which matches exactly the split.bin posted earlier)

Please someone confirm this!

Why 100?
Just do it and check if it opens...

Please someone confirm this!

Confirmed! Need password there.

I try opening it and it prompts for a password.

I subtracted 100 because in several examples of .7z files I have, there was a section of 00000$0000000 a few bytes in.

But this raw data has ddddd<8d>ddddddd which to me looked like it was rotated.  That means subtracting 100 bytes.  And voila, I see a correct 7zip header at the start!

Someone try running my program on Space.mp4 and let me know if I'm not totally insane here....

I'm going to try variations on what came out of the video for password.

You guys are so blind....

You guys are so blind....

Ba duda, ba duda, ba duda, badu? I think too. Where is a white rabbit now?

For completeness, same goes for 24_clash.wav.

I am off to bed.
I have wasted enough time on this and before I go to bed let me say: ask "Alice"......

Maybe you will get there

I found the original video. It's here: https://www.youtube.com/watch?v=3rysbn9bZ54

Riffing off of that, I've tried these passwords, including the 2*sha256 versions of them. None of them worked for me:

i think we need to decode the encoded 2mb splittet from the Space.mp4...


maybe that is also needed for it:
Coin_Artist: A secret
2009
And then there was Bitcoin
Monsters!
space
more words
Muhahahhaa
Satoshi was here
That's all there is to it!
Such Wow!



if it is the last puzzle, then it is for shure the hardest from all!

maybe something like xor the data with every words in rigth order...

Strike "2009" and "That's all there is to it!" from your set. I diffed against a clean 0.5.0 install of that game and those words exist in the original docs.

If you speed up 16_kaboom.wav by 225% or so it's clearly a song fragment, and is not the original game sound. I thought it might be a snippet from Tetris but it's from something else. It's naggingly familiar, quite possibly from another game from the era. For a few minutes I was convinced it was an 8-bit rendition of "Rawhide".

I haven't fully decoded all of the other unusual sound files (20-25), but they appear to all be QR codes, and half of them have led me to Again.7z.

Are you checking hashes of files 17_heart.wav and 18_heart.wav? For me they seems different when in original version they are identical. May be version differnce, I must re-check.

cmp tells me 17 and 18 are identical between the version we downloaded and the 0.5.0 install version I found at http://mspencer.net/daggorath/builds/

ha, and I was just about to call it a night. now I need to ponder how I am close!

I checked all these files and they all have the exact same QR code.

Must be on the right track.  Or you're being chastised.  Lol.
