Half-life 1 runs in NT 4.0, so it should be compatible with directx3. However, I've been unable to test half-life 1 in 95 using directx3 because of its Win95/directx6 detection routine.
In removing directx6 from 95 and then installing dx3, I noted shell issues with the command prompt. I'd have to reinstall 95b to verify this wasn't caused by the removal process, but reinstalling dx6 fixed the issue. In addition, dx6 with its native s3 driver allows for low resolution modes, so dx6 should be ideal for this era of games.

DxWnd application has a hook for the OS version. It may be modified for NT 4.0 (hl.exe refers to getversionexA)?

For compatibility, it is possible to run half-life like this: hl.exe -dibonly -wavonly. This parameter may help with any audio lag: _snd_mixahead.
However, it tests for directx6, so it seems like a requirement and it does add the low resolution capable video driver; to run half-life without directx, then "copy the dx6 versions of ddraw.dll, ddraw.vxd, ddraw16.dll and the dx3 or dx6 version of ddhelp.exe into /windows/system/".
Starcraft and the Diablos run with dx3. I haven't determined whether they are dependent on a ddraw surface or have a DIB mode. Since dosbox-x is now compatible with these configurations, I'll close this thread.
Update- Another post showed that these changes to hl (v1.0) will enable it to run in 95 with dx3: 00020717 74 to 75 0002BC8B 1C to 00 0002728E 04 to 00
Noted that Starcraft, Diablo 1 and Diablo 2 require directx3 only, but I didn't test against directx2. I was unable to start these games without directdraw (dib mode), however.
Unreal Tournament (and likely Unreal) support dib mode in a window (such as 320x240 or higher), but not full screen. I couldn't find a wrapper to create a borderless window which fills the screen in 95. Others have even run this game in NT 3.51.
Didn't test Age of Empires 1 and 2 which reportedly have low minimum requirements in 95.
