Metal Gear Solid 5 cassette tape

Btw, I did find these two files.
They have both half megabyte of data each but cannot be played in any media players.
Just wanted to share since these two files have the same identical length as the tape in the webm, which was unusual when I was checking the sound files unless it was just some weather effect.

a.pomf.cat/mymlbt.wav

I managed to extract a clean audio sample from the cutscene file (located in master/chunk0.dat/29b01ccdace57.fsm). I've been unable to load it under openMSX, perhaps there's too much noise and popping in the background, or there's simply nothing readable there. Hopefully some of the people here will have better luck with it. For reference the audio data was interleaved throughout the file, the relevant chunks just needed to be identified and reassembled.

...calling Hideo to chime in....ring, ring.
the plot thickens.

soooo...any updates? has anyone tried combining the two tapes into one?

Hello there, just posting some ideas popping up and then I will let the the people with actual skills do their thing ;-).

Some things that popped up:

- combining the data.
- replace data file found in Ground Zeroes for file found in Metal Gear SolidSolid 5? Maybe the new sound will trigger something?
- perhaps a combination of two options above?
- combining data with part B Reversed, as if it's the other side of the tape while playing it?

Just wanted to out it out, thanks for trying all!
