Metal Gear Solid 5 cassette tape

If you download the original OGG file and convert it back to wav (I used 'oggdec'), I get a WAV file that I can load with openMSX.

@Manuel I tried that, but it ends just like previously described, with “Found:VOL2” and then nothing. Do you get something else?

I'm afraid it is not a BASIC program. It just has the CLOAD header and VOL2 name, but that's all.
The content seems binary data, perhaps dummy Z80 code.
This is what I got:

#D3 x 10 = CLOAD header
#56,#4f,#4c,#32,#0,#0 = VOL2 name

Yes, I calculated the frequency, then decoded all the bits and then converted to bytes checking the start and stop bits.
Perhaps some bits are not correct because the original file used in the game is not good enough.

Sounds logical, it's very short to be a real program though
