There are three versions of the emulator. Original author's Win32
driver, abandoned; modified dosbox, by same author, which is
maintained; and Linux ALSA port. Neither works here with FreeBSD (of
course), but since original versions were too MSVC-specific, I got
emulator core from that Linux port. In current state of my code there
is just another midi driver, `mt32' which outputs sound in a manner of
our adlib code, i.e. to whatever backend supports.

Exactly, that's what I've done.

Well, it is kanji font ROM, which eventually could go away if somebody
will write code to use some free font. See code starting at line 899
in scumm/scumm.cpp

Nobody even tried to say that. Of course not, like we do not
distribute any non-free games.

Right now I use target-specific `extrapath' parameter, though I
personally thinking about adding system-wide extrapath as well.

Nothing changes in this aspect as we already got used to handle
multitude of warez requests in different shapes and tastes.
