I have not so much time during the day. Also i was struggling with the drivers of this soundcard...
First, i wanted to run it under DOS, so according the readme of the driver package, i have included in the autoexec.bat :
C:\MAD16\SNDINIT /B
SET BLASTER=A220 I5 D1 T4
Second, i've tried also the windows driver installation, but according to the manufacturer, the OPTi 928 based card (Spacewalker Sound System 48, HOT-223) has only DOS and Win3.1 drivers.
Then I've found also some OPTi reference drivers (928) for windows95. It turns around it was for the Turtle Beach Monte Carlo. I've tried it, and it works (digital sound + OPL3 FM synth). Under Windows, there are several ports which i can choose (530h, 604h, ...), but no 330h which is typical as standard midi port.
Actually, i have not so many games installed with general midi support. For example, i've started the sound-setup's of the games: Biing, X-Wing and Tie-Fighter.
Today, there was also somthing stange: Testing the "imuse" sound-program from tiefigher, after a reboot i can select successfully the settings (SB-Pro, 220h, I7, D1, T4)
according to the entry in autoexec.bat, and after re-try this test it doesn't work. It's only this "imuse" setting.
I thought that the mpu401 interface under DOS is supported without any drivers. Then I've found also some Driver packages from the OPTi 929, where a mpu401 driver is available for windows.
Under Win95, I have tried to change some settings in the system.ini file, but at the end i was not successful to access the mpu401 port with the dreamblaster.
From here, i have no further progress with this card so i'll try another ISA card next time.. 😒
