Metal Gear Solid 5 cassette tape

Yes. Strangely, while comparing it with a working tape version, I realized something:

It's hard to say (could be just be a side effect from corruption) but the reference to PC-6001 seems to have been removed? @tiny_yarou and me went through completely different paths with the same result, too.

Thing is, in order to replicate this, someone would have needed to load the original tape on a machine/emulator, change the line, then save the audio again. And the only reason why anyone would have to worry about that is if that string would be readable/accessible somewhere in-game?

My guess is that the "PC-6001" string was removed and it is not related to corruption.
If it was related to corruption, probably some weird characters should be shown.
Also, the asterisks could be misplaced, but they are perfectly located.

I don't think the string is accesible in the game. In that case it should decode the audio file that was mixed with music in a video (IIRC). From a programmer point of view, that is more complex that just store the needed binary data.
I don't know why they removed the string but perhaps they tought "What if a retro-fan decode the signal and finds we are loading a PC-6001 tape on an MSX2 computer?" (^_^!)

One thing more, this tape is supposed to be named "VOL1", and the tape from MGS GZ was VOL2. So probably they used another fragment/part of the game in that case.

Joke: So OPERATION INTRUDE N313 is Portopia serial murder game? XD

I think we might be playing the game in a way they had not anticipated .

Probably they could not get the MSX version of Portopia to include it in the game.
That's why Snake gets angry and hits the mirror in the cut scene. Because the PC-6001 tape does not load in his MSX2 computer. XD
