Soundblaster/adlib/tandy/CMS/joystick/MPU401 seem to work 99.99%, Amnesia demo freezes at launch.

Gravis Ultrasound compatibility seems very broken. DOOM fails at DMX_INIT for ultrasound, DOSMID midi playback has no audio, Duke3D will not play audio or music but plays normally otherwise. Second Reality and Crystal Dream II seem to run flawlessly but Unreal freezes during execution during a spaceship scene.

I'm actually wondering if I've got midi playback configured correctly but I'm using the zip file from the wiki and simply set ULTRASND env variable to point to that folder!

Did the Picogus soundblaster code originate with Dosbox? Perhaps Amnesia is suffering from the same issue reported here. I just tested the SAGA demo that's also listed and it hangs in a similar fashion at launch, so I suspect your SB emulation have inherited this bug somehow?

I also would report that a Gravis Ultrasound PNP Pro initialized with UNISOUND appears to work flawlessly with ultrasound applications and demos on this system, if that's useful information.

edit Spoke too soon. Starting to hit games that are locking the guspnp up, so I assume something about the SBC is just not working out...
