Could the soundcard source from DOSBox be used as a starting point in creating a virtual soundblaster for DOS proper?

Not really. DOSBox just uses SDL for sound and graphics.
Need a VDD, a driver that loads in DOS, that communicates with the OS/2 sound system, either DART or directly with UniAUD. The VDD would present the same interface as a SoundBlaster or whatever is chosen.
Be nice to have another one that does MIDI as well, perhaps interfacing with timidity or fluidsynth. Not sure how well sharing the sound would work then though.

Hi Mathias.

I will try the games you listed. Yesterday I tried "Secret Agent" with the same results (It was the first time I played that)

I'm looking at Extreme Pinball (Medieval Knights):
- On DOS VDM Full screen, I just run "Extreme.exe" and the screen shows some "color vertical lines" and quits. Is it the same results you are experiencing?
- eGamer does not seems to have that game on the list for any setting suggestions.(It has a suggestion for the older one called Epic Pinball)
Suggestions to learn more about how to take any log of different alternatives to try are welcome.


On other DOS game subject:
- It would be interesting also to know if there is a DOS game that does not work (or that runs bad) on DOSBox and test it on VDM. I haven't found any but if something appears let me know.

Hi Martin! : )

About Extreme Pinball:
I've had the same effect, indeed. - But setting the sound to "no soundcard" (Setup.exe), which unfortunately leads to no sound at all (speaker not supported in this game?), plus adding "mode co80" to autoexec.bat seems to have done the trick. Now all the tables can be played. \^___^/ - Yihaw! So this game actually works in OS/2's DOS full screen. Sound needs to wait for the maybe upcoming SoundBlaster "mapper" driver.. ; )

Mathias:
Now I've tried the game [Electro Body]. All with default settings for DOS Full Screen. Autoexec.bat with a "mode co80" line, Config.sys unchanged from ArcaOS installation.

First I was greeted with a message, that Electro Body needs atleast 580.000 kb of free memory.
The "mem" command said I have 591.408 kb free... mhmm..

Then I've left the DOS fullscreen window, and set it's DOS memory properties to DOS=HIGH which results in a whopping 625.856 kb free!!! *_____* WOW, any game runs with that whole lot of free memory!! :D

The game starts now, and I could play... (even has PC speaker support) BUT, it runs terribly slow. Do you know a trick there? (Quit the game with F10)

Martin Iturbide:
Hi Mathias.

I had tried just right Electro Bod. DOS Full Screen, no pc speaker, and setting DOS=HIGH works.
It runs and I'm playing it, but I don't see it terrible slow, the character moves ok, it is complete playable.

Regards
