z26 can save its audio data to a file (any SDL app can):
Set the environment variable SDL_AUDIODRIVER=disk, then run z26. You
shouldn't hear any audio.
When you exit z26, you should see a file called sdlaudio.raw in the
current directory. This is raw 8-bit mono unsigned audio data at either
31400Hz (for an NTSC ROM) or 31113Hz for PAL). If you're using Linux
(or any UNIX-like environment, including Cygwin on Windows), you can
use the sox command to convert this to a .wav file, which is a lot more
convenient to deal with. The command would look something like:
sox -t raw -c 1 -b -r 31400 -u sdlaudio.raw -t wav -c 1 -r 44100 -w -s audio.wav
(Note: that's from memory, I may have mangled it badly)
If you're not into UNIXy command line stuff, I'm sure there are plenty of
Windows-native audio conversion programs that can play the sdlaudio.raw
or convert it into a more useful format... but not being a Windows user,
I can't tell you the names of any.
Hope this helps.
