This sounds like something I could look into. But the comment in the source code of that script is a dead giveaway, from one word: "nonlinear". Nothing would stop you from extracting the sound data if you know the format of it and where it's located, but non-linear means that the amplitude steps are not evenly spaced. In other words, you need to know the conversion curve of the SMS/GG DAC in order to restore the original audio from the sample data. This is all fine and well, but requires additional research on the hardware if it's not already documented somewhere. And likewise, it's impossible to know the correct sample playback rate without figuring out what the ROM is actually doing.

And yes, that Cannon fodder sample playback is horrible. Thank you for reminding me of this. I've now uploaded a video with the audio reconstructed from a ROM rip, in case you are interested.

However, the Cannon Fodder audio as played back by the ROM always reminded of a version of Forever Young that V/Vm did for a Playstation commercial that never got aired. My own favorite theory is that they left the audio playback that way as some sort of homage to that commercial, although it's more likely that that's not the case.

I will bookmark this thread for future reference for... a thing.

Also, fixed the title. You can edit the title yourself. No need to create a new thread for that purpose.

Is that auction only open to people in Germany? It says "Versand nach:Deutschland". (Asking for someone else.)

There's a schematic from the SAM COUPE/ZX Spectrum here. Copy the analog part. You then need to add an external 8 MHz clock and control lines for the CPU interface. A0 controls which register is active. To write data, put it on the data lines and pull /WR and /CS low for whatever time the datasheet says.

Edit: or I guess you're looking for something more complete...

Oh snap... I forgot to consider that those things would get filtered.
Well, click quote on my post and look what it actually says.

SEO. Google ranks pages based on how many links they have. These spam various forums and posts links between each place they spam. That way, google (supposedly) thinks these pages are really hot. And then from each spam post, there's also a link to their real page, the one that sells something or so.
