Hello.
I extracted the sound code from my
3 years old local dosemu branch and
re-diffed it against the current svn.
This took lot of a hand-work, so the
mistakes are possible.
A quick test shows that the adlib
now works on x86-64. But many progs
(non-adlib ones) are still mute because
the cpuemu doesn't exit after every port
I/O the way vm86() did. The result is
that run_irqs() doesn't come in time.
If someone is willing to work on this,
here's the patch.
