I was looking at Jo22's forum thread, "Emulation on MS Windows 3.1x?" and I've been thinking that I want to start a similar thread here.

Windows NT 4.0 did provide greater stability over Windows 95, but it was less flexible from a desktop perspective. With nearly all software that were written for Windows 95 or Windows NT 3.51 are able to run on Windows NT 4.0, many of the 3D games wouldn't, because of the limited DirectX support. While Windows NT 4.0 was limited to DirectX 3, it can be updated to DirectX 5 (unofficially).

In case you're interested, this is what I've found for Windows NT 4.0:

Atari 2600
1. No$2K6 1.2: https://problemkaputt.de/2k6.htm
2. Stella 1.4.2 (Win32 version known as StellaX): http://173.25.133.87/Downloads/Emulators/Atari/2600/StellaX/

Atari Lynx
Handy 0.95: https://sourceforge.net/projects/handy/files/ … y/Handy%200.95/

Game Boy
NO$GBA: https://problemkaputt.de/gba.htm

Nintendo Entertainment System
NESticle 0.42: https://emulation.gametechwiki.com/index.php/NESticle

Super Nintendo
NO$SNS 1.6: https://problemkaputt.de/sns.htm

Commodore 64 emulators
WinVice 1.2.2: https://csdb.dk/release/?id=79698

Arcade
MAME32 0.36: https://www.progettosnaps.net/mameui/

Because Windows NT 4.0 has limited DirectX support, if you want to run emulators that require DirectX, it would be best to use Connectix Virtual PC (up to version 5.2), QEMU 0.9.0 or Bochs 2.3.6 and run your emulators under Windows 95 guest (that has DirectX 8 support). If you have found a emulator (without DirectX support) that will work under Windows NT 4.0, please post a link to the emulator in question here.

I might update this post and provide some screenshots later on if I can.

...What? If you're going to run emulators on Win95, you might as well skip virtualization on NT 4.0...

Emulation and even virtualisation can be done on Windows NT 4.0, just without the use of or very limited use of DirectX. I have ran emulators on Windows 95 before.

Finding a good emulator to run under Windows NT 4.0 is going to be challenging.

I think BGB works on NT 4.0,as it offers GDI (only used it),OpenGL and DirectDraw.

Due to this,you should include it.

Also the already existing section only focuses on GBA/DS

BGB, a GameBoy and GameBoy Color emulator requires DirectX 7, which won't work under Windows NT 4.0 and in Windows 95, it might include dependencies that don't exist on the OS. BGB 1.5.9 requires Windows 98 or later. Windows NT 4.0 can only support up to DirectX 3 (DirectX 6.1 unofficially).

I only used gdi but it does not require directx7 or windows 98

I remember having a beta of DirectX 5 that worked in NT, but I never read about DirectX 6 or later working in NT.

Also, there was a version of WinUAE that worked in NT (using that DirectX 5 beta) that you could download from the main WinUAE page. I think that DirectX 5 for NT could be downloaded from the same page, but I might be wrong.

I had heard then about the file "DX60eng (winNT4).exe" although I never tested it.

Anyways, Dx5.0 for NT4 is here:

NOCASH series emulators (NO$GBA and such) depend on virtually nothing and from what I could see via Dependency Walker it should be able to work on even NT 3.51. These are very good emulators and there were even DOS versions for some of these.

Actually some DirectX 8.0 libraries can be made working on even NT 3.51 (namely DirectSound/DirectMusic and some DirectPlay), just that you need a different way (like REGINI) to insert the necessary registry values as NT 3.51 doesn't provide the method we use in 9x/2K to import registry keys.

EDIT: Did a little inspection with Dependency Walker. Looks like newer D3D/DDraw really can't work on NT4 due to missing symbols in GDI32 and USER32. Checked some other parts and found these should be usable as of NT4 SP6:
- DirectSound/DirectMusic 8.0a
- DInput 7.0
- DirectPlay 7.0

This kind of fits the fact that DirectX Media 6 as well as DirectPlay 6.1a were actually released for NT4, despite there were no full versions of newer DirectX for it.

BGB v1.03 should work in NT4 and Win95. The recent versions are linked with opengl and directx9, although there may be other dependencies.

I'll try BGB v1.03 to see if it works under Windows NT 4.0. Does anyone have a link to BGB v1.03? Just curious.

I use Famtasia 5.1 on my Windows NT 4.0 PC. This NES emulator was popular in the early days of tool-assisted speedrunning; it uses the GDI for rendering and should also run on Windows NT 3.51.
Here's a link: http://web.archive.org/web/famtasia.at.infose … o.jp/fam510.zip
A person on the TASVideos forums wrote a number of patches to fix bugs and inadequacies in the emulator.
Here's a site where one can download a patched version: http://bisqwit.iki.fi/utils/famtasiapatch.php
Make sure to uncheck Occupation slider fix; otherwise, the emulator will make the system unresponsive.

I can confirm that NO$SNS runs on Windows NT 3.51. The Open dialog won't work, so the emulator should be run from the command line with a path to a ROM file as the first argument.

Not all PCs can run Windows 95 natively, and not everyone wants to run Windows 95 natively.

Another emulator I use is Snes9x 1.43. Here's a download link: http://web.archive.org/web/0/ipherswipsite.co … -1.43-win32.zip
This emulator offers a number of features over NO$SNS, such as cheats and an OpenGL renderer that works on my PC. OpenGL is only used in the bilinear filter – it doesn't look particularly good, but it prevents the emulator from slowing to a crawl at higher resolutions.

Selecting Load Game... in the File menu may cause a crash. If this happens, start the emulator by dragging and dropping a ROM file onto the Snes9x icon.

The emulator may also crash on startup, showing one of two messages: "Exception: access violation (0xc0000005)" or "Exception: (0xc06d007e)". These messages only appear if the FMOD driver is selected.
The first message appears when fmod.dll fails to initialise, either because there are no audio devices or because another application is playing audio. The second message appears if fmod.dll cannot be found.
If the FMOD driver is not needed, one can edit the registry so that Snes9x starts using its own DirectSound driver:

REGEDIT4
[HKEY_CURRENT_USER\Software\Emulators\Snes9X\1.31]
"Sound Driver"=hex:00,00,00,00
