Why would it be Z80 opcodes?

Hey guys. Thanks a lot for looking in to this. It's awesome that communities still exist for retro computing.

Could somebody explain, in lay terms, what exactly you guys are discovering? Is it conclusively just a bunch of nonsense? Does the presence of a CLOAD header and file name indicate that this is more than just random noise? I have no idea how any of this stuff works, but a few months ago the Metal Gear community gathered a lot of data for a potential ARG that never seemed to go anywhere. Maybe that stuff could help?

Anyway, here's the highest quality .wav file I'm aware of. Lossless capture straight from the game. It's about twice the size of the one you guys are currently using. I checked the waveform in audacity and it looks pretty clean. Good luck!

@GarlicJockey, it's the same wav file I linked in my first post.

I decoded the sound file directly from the original .wem file, but it is not good enough to be 100% sure of the content.
The file seems an MSX BASIC program (CLOAD format) but after the first header (file type and name) the next block (BASIC program) seems binary data.

So, does not seem to be a secret message, a BASIC program or any other "surprise". But it is nice to find that Konami/Kojima/whoever still has the MSX in mind when developing a new Metal Gear game.

On a whim, I tried reading it as 16 by 16 sprite data, but that doesn't give anything useful.

I was thinking, didn't Kings Valley 2 have this odd tape storage format for your own levels? It was basically a header and then a small binary dump.

I can't remember how many other Konami games supported reading and writing data to tape, but it can't be that many.

A metalgear save state was already ruled out, but a kingsvalley 2 level is a cool thought Smile

Has anyone actually tried loading MG save using that file with readable VOL2 header? I guess it should be the name of save slot that you manually type in game.

Based on the image included in the MRC Monthly Newsletter in which this topic was mentioned:

Which of the MSX.org mods thinks music by the Dutch band Spinvis sounds like MSX data garbage? :P

I tried to load it into MG1, but it didn't see it as a save file.
