I've just tested out your patch.
In general, it's perfect :) except that most programs still can't detect it and
there's no music :(
(btw, when you write the music code (please!), get a game called "Hocus Pocus" by
Moonlite Software -- it has really, really good music)
Here are some of the more interesting results of testing (i.e. the results that you
probably want to know about):
Program no sound patches snd-patch1 (I think)
snd-patch6-1.1.2.diff.gz
(sb pro) (sb or sb clone) (sb or sb
clone)
Good
----
One Must Fall 2097 perfect music skips & stutters perfect
Liero no sound sound stutters perfect
Count Down lock up perfect,clicking
perfect,clicking *
Scream Tracker 3 no sound perfect perfect
Warcraft II stutters badly perfect perfect
Shell Shock perfect no sound perfect
Nice, the top three are my favourite DOS games :)
Warcraft 2 is misdetecting the sound emulator as "Ensoniq Soundscape" (which
incidently is my real sound card).
If I start Count Down and wait for the initial scream (yes, this is an interesting
game) to finish before pressing a key,
the intro music and the sound is fine. But if I interrupt the initial scream (i.e.
don't wait for it to finish before pressing a key), lots of sound
(almost all the sound in the game) disappears and if there is any sound, it lasts for
a few seconds and then stops; with the into music, it skips
entire segments and then stops :( This game is commercial and is by Access Software,
which has been bought out by MS so I can't give it to you :(
This behaviour occurs on the 2.4.7 kernel.
If I use 2.4.3, Count Down _always_ stuffs up no matter what I do.
Really Bad
--------
Clyde's Revenge no sound bombs out locks up (dosemu complains
about vfree'ing something)
Mugen no sound exception exception
Commander Keen 4 no sound locks up no sound

The latency is now very obvious in Liero, with an annoying 1/2 second delay (perhaps,
you could put an option in dosemu.conf to specify minimum OSS buffer size?).
The clicking still happens in the game "Count Down".
btw, I've found out when and why OMF2097 stutters. (I'm using a Pentium II to give
you an idea of how fast/slow my computer is)
If I select "Sound Blaster (mono)" and then choose "Very High Quality" or "Ultra High
Quality", it misses or repeats or a few beats.
If I select "Sound Blaster (mono)" and then choose <= "High Quality", then it's fine.
In an unpatched DOSemu 1.0.2.1, If select "Sound Blaster Pro" and then choose "Ultra
High Quality", there's not a problem.
So, I think your code is a little slow :(

This doesn't seem to happen anymore (after snd-patch-1).

Then, I hope you don't get a real sound card... :)
Most new PCI sound cards don't come with DOS sound drivers anyway.
And ISA ones are nowhere to be seen.

Segfaults have always been happening when a program tries to start with SB (even with
unpatched dosemu 1.0.2.1).
To reproduce it, start KDE 2.2 (make sure ARTS is running and hogging /dev/dsp) or
TiMidity++ and then play your favourite :) game OMF2097 and you get:
ERROR: unexpected CPU exception 0x06 errorcode: 0x00000000 while in vm86 (DOS)

The log became 8MB long so I deleted it (it complained about "SIGILL" a lot, anyway).
The strange thing is that I just ran it again (ARTS was still active) and OMF2097 just
started without sound and dosemu didn't crash.

It's a lot more than a clone of Mortal Kombat...
There are lots of secrets in the game (in both Single Player and Tournament) including
"Scrap Moves", "Destruction", secret challengers and secret levels.
Robot enhancements (like triple-concussion cannon for Jaguar :))....

What robot are you using? I tried to copy this tactic and I got defeated first
round...
May be you should play on a higher difficulty setting.
Normally, I use Jaguar, Katana or Electra and only just beat the computer on Ultimate.
> The last robot (the biggest) was the easyest one to beat...
He is really, really hard.
May be you should play on the "Ultimate" difficulty (highest difficulty level).
You actually need a cheat to do this: go to Gameplay and hold the right arrow key on
the CPU/Difficulty setting - you should then get the "Deadly" setting.
Go back to the main menu and press O+M+F (or was it 2+0+9+7?) and then set the
CPU/Difficulty on "Ultimate".
Now _that_ requires a lot of work to beat the computer (also opens up secret levels in
Single Player mode).

It's the best fighting game ever! It has more depth than most mindless,
button-bashing fighting games.
About as good as "Street Fighter Zero Two" :)
I have a bunch of other games that don't detect the sound card as you said:

Please merge these soon. It is quite noticeable :(

Recording? Do you mean saving what comes out of DOSemu as a .WAV file or similar?
If so, how can I do this?
I really like the patches and hope to see them in the next "offical" version of dosemu.
Soon I can say goodbye to Win98 to play DOS games with sound :)
Thanks,
