Would be nice to have SFARK support. SFARK is a compression algorythm for soundfonts
files. support on macosx is almost gone, but many files are compressed using this algorythm.
there used to be informations here: http://melodymachine.com/sfark.htm informations

Issue 668 has been merged into this issue.

paracelsus:

Having read that, I am almost tempted to say support should not be implemented, just
to discourage use of this format. Nobody should ever use it, and rather than try to
unpack files in it, it would be far better to tell anyone who used it that they should
stop.

I might still do it, though. Depends on how complicated it is to get that code working,
though. (It seems to really might be complicated if you want it to actually run cross-platform,
due to the idiotic reliance on the 387.)

It appears that someone has done a bit of reverse engineering here:

If anything does turn up, though, post it in here.

Sigh! thanks for answering so quickly anyway. 

I tried to look for source code and sent an email to the former author but they all
seems desappeared in the dark.

paracelsus:

It doesn't look like there's any documentation for the format, so it would have to be
reverse engineered, which takes a lot of time. I probably won't have the time to do
that anytime soon for such a minor format.

If anyone else wants to have a go, though, I can accept patches. Or if anyone can find
any more information about it, that would help too.
