Metal Gear Solid 5 cassette tape

If we're going to do wild guesses, maybe it's a GameMaster savestate.

Japanese coders don't know Basicode, it's a Dutch invention

I decoded it using the right frequency. I think they concatenated different chunks of data. That's why there is no pause after the first header. Also, there is no end file token.

I wasn't about to read through 6 pages of comments, so please excuse, and ignore this if it's already been brought up.

There is a trailer that was released that had a Morse code message in it. The decoded message reads-

"GENERATING IMAGE HOLD SCENARIO LOADING HOLD ACTIVATE PHANTOM PAIN DOT MEME HOLD ERROR ERROR ERROR ERROR"

I don't have any experience with with the MSX so this may not be relevant at all but it does sound like a program command, right?

I know I'm bumping something super old here, but this tape is really bothering me and you guys seem to have the best handle on it. I was wondering if anyone had tried running the audio data through a computer circa 1975 when the game takes place like an IMSAI 8080. https://en.m.wikipedia.org/wiki/IMSAI_8080
If anyone is meticulous enough to do something so accurately, it would be Kojima.
