Doesn't work that way, they're entirely different code paths with entirely different functionality under the hood.

No worries.

I've managed to get Sound Blaster to partially work in Windows 95 thanks to recent changes with the Northbridge and Southbridge updates (mainly Southbridge I think though). For those interested:

- Be sure to set MESS to use "sblaster1_5".

- Install the drivers from within Add/Remove Hardware. Be sure to have the CAB files handy or CD image you used. By default, Windows sets the following resources:

I/O: 0220 - 022F
I/O: 0388 - 0389
IRQ: 05
DMA: 01

- After pressing Finish to complete the installation of the drivers, you'll get an error message in the form of a white box come up with both Continue and Ignore buttons, keep pressing either of these until the box goes away. Don't restart the PC yet when prompted.

- Right click on My Computer and click on Properties, then click on the Device Manager tab at the top. Double click on Creative Labs Sound Blaster (it'll have a yellow ! next to it) then click on the Resources tab at the top. Change the IRQ from "5" to "7" and reboot.

When Windows starts you'll hear the default start up sound, however it's not perfect. It starts, then gets stuck almost right away and keeps looping indefinitely. I found the best way to stop this was to click on the "Sounds" icon in Control Panel, then play a Windows sound and press the stop button, this will stop all sounds.

You can use Windows Media Player to play MIDI files as well, which play without a problem. I would suggest you use the i386 driver to play and hear the sounds perfectly, as Windows, (at least for me anyway), runs at 100%, and only half that on the i486 driver.

FIFA 97: (C) 1996 EA Sports.

Wasn't expecting this beast to work, but here we are!

8088 Corruption (C) 2004

8088 Corruption is PC demo designed to display full motion colour video on the Intel 8088 with a CGA video card and an original Sound Blaster using ASCII characters.

I had attempted to run this demo a few months ago, but the Sound Blaster emulation wasn't good enough. Now with the Northbridge / Southbridge updates, it's now possible.

I was not able to get this demo to work on the ibm5150 driver, (all I get a blinking cursor?) but I was able to get it up and running perfectly on the at486 driver using CGA and the Sound Blaster.

The screenshots don't do the demo much justice, best view it on YouTube or download it and watch it for yourself!

Before the demo starts it asks if you are using a real CGA card or an emulator, all screenshots below are from me telling the demo I am using a real CGA card.

Huh. 3D graphics on what's probably the Tseng ET4000. I've seen everything, apparently.

You've never heard of a software rasterizer before? Damn, dude. How's that N64 emulator coming?

I was using the ET4000 for FIFA 97, yep. FIFA 96 should work as well now. As JD said, it's just software rendering. All the other 3D games I have taken screenshots of, such as Quake, Grand Theft Auto etc... were all taken using the same video card.

MAME v0.1 works perfectly as well, even with Sound Blaster sound, but takes a big performance hit causing MESS to run at about 40% on the 486 driver. I suspect most of early MAME releases for DOS should work as well now.
