SB: Fix Windows 9x support (unimplemented DSP read and write status port bits should be pulled high)

[ianhan]

This change fixes Windows 9x driver support for SB mode by implementing a quirk the driver expects (unimplemented status bits should be pulled high). PCem does the same thing.

Tested with DXDiag and some audio playback apps. Tested with Jazz Jackrabbit and Cubic Player outside of Windows under DOS.

any word on this being added to the main fork? would be nice to not have to build this on my own, I keep getting stuck linking tinyusb

[ianhan]

I think @polpo plans to merge soon. For building yourself, after cloning the repo you can do something like "git submodule update --init --recursive" to set up the submodule repos (including TinyUSB - otherwise you will get a linker error). After doing that, it should just build (might need to pick SDK 1.5.1).

Thanks so much been working on that for days intermittently :)

OK - to build:
SDK 1.5.1
pico-extras 1.5.1
latest cmake (if your using ubuntu / xubuntu ) its out of date.
clone repository (can't just download the zip need to use GIT and select the correct branch)
run git submodule update --init --recursive from the root of the repository
cd to sw in the root of repository
mkdir build
cd build
cmake -DPROJECT_TYPE=MULTIFW ..
make

wait a while
you want picogus.sf2

that being said I most likely missed something.

at your own risk 100% --- good luck.

can verify diablo 1 works on my overclocked ps/1 2155 DX2 / 66 (running at 40mhz fsb so actually 80) in sound blaster mode with no sound glitching ... frame rate is low because its a 486 and requires a Pentium this is windows 95 OSR 2 with the stock windows / directx sound blaster drivers.

Awesome, thanks!
