You can play Doom, Doom2 and Final Doom with the orignal Doom95 Port from id Software / Microsoft. Files:

HAVE FUN! :)

Doom95 came packed in with Doom 2 and it was love at first click. So many LAN parties started with this little piece of software.

D95 was shit AFAIR

Doom95 was not by id Software, it was made by Microsoft. Fun fact: Doom95 was developed by, among other people, Gabe Newell, who'd later quit Microsoft to fund Valve...

There are many issues with Doom 95, it doesn't render sprites in their proper aspect ratio, it doesn't play back sounds at their proper sample rate, etc. I'd really recommend using a modern source port instead.

Better off using ZDoom to get an enhanced classic experience. It is not 100% accurate to the DOS original but you can't beat widescreen and nice 60 FPS support if you ask me.

ZDoom is always the best choose for games with the Doom-Engine. ;) Thank you for the information. I found this in the EXE file:

I actually play (first) Half-Life in 1024x768 rendered in Software mode.
Not because my PC is shit (which it's not), but it feels more nostalgic this way.
This's how I first played HL.

Yeah, copyright is a complex issue. The Doom engine was developed by id Software, then Microsoft ported it to Windows, but the copyright remained with id Software since they were still the ones who sold the game after all.

Microsoft? Never knew that. Then am I just wrong about it being on the big box Doom 2 disc?

If you mean the Anthology collection, no, you're not wrong.

Microsoft made the Doom95 port, but that doesn't mean it was commercialized by Microsoft. The game was still sold by id Software and their publisher of the time (Activision).

Note however that modern distribution of Doom (on Steam or GOG, or in the recent console ports like on PSN, or the Doom Classic engine bundled with Doom 3 BFG, are not derived from the Doom95 codebase. Either they use the original DOS engine with DOSBox, or they are derived from the original Doom codebase as kept by id Software (which is different from the source code they released to the public, thanks to Bernd Kreimeier's intervention).

All later (v1.9) releases of Doom II and Final Doom came prepackaged with Doom95 (not sure about Ultimate Doom, but probably the same). In fact, for Final Doom, it was used as the default game executable (although DOS binaries were included for those so inclined).

As for the Doom source code release being derived from the Linux port, instead of the original DOS version - that had to do with licensing issues regarding the sound library that was used. id couldn't legally release that code (and weren't on good terms with the guy who wrote it) So it was the (slightly modified) Linux code, or nothing at all.

I've tried using Doom95 on Windows 8.1 and let's just say it's not pretty. I might give another crack at it. You could using compatibility settings to get something close to vanilla Doom on DOS with ZDoom. Here's a forum post on Doomworld that shows some settings to use and load them into a *cfg file.

If you want something closer to vanilla than ZDoom but still with higher res than 320x200 scaled and uncapped framerate, I'd suggest taking a good look at the following ports:

Eternity Engine
PrBoom+
Crispy Doom
