Doom for 16-bit DOS computers

For those that wonder how it looks, I found a video:<p><a href="https:&#x2F;&#x2F;twitter.com&#x2F;FOmmetje&#x2F;status&#x2F;1696266683756003451" rel="nofollow noreferrer">https:&#x2F;&#x2F;twitter.com&#x2F;FOmmetje&#x2F;status&#x2F;1696266683756003451</a><p>or if you prefer:<p><a href="https:&#x2F;&#x2F;nitter.net&#x2F;FOmmetje&#x2F;status&#x2F;1696266683756003451" rel="nofollow noreferrer">https:&#x2F;&#x2F;nitter.net&#x2F;FOmmetje&#x2F;status&#x2F;1696266683756003451</a>

&gt; Super slow because for every frame every necessary image is read from the hard disk and for every calculation involving a lookup table the hard disk is also accessed<p>The 8086 was limited to 640k, a 286 could actually do 16MB with paging.<p>Is the problem simply the ram limit on the 8086? Is that why assets have to be reloaded off disk constantly?<p>Couldn’t a 286 with enough memory handle it (if you were emulating that processor)?<p>I’m curious what the issue is.

But wasn’t Doom originally developed for “16-bit DOS computers”? That’s the way I originally played it, by installing it from 3.5” floppies as a DOS program on my Windows 3.11 PC, although it was a 486&#x2F;33 IIRC. I could play the entire game, save my progress, and I had sound via SoundBlaster. In fact, I even installed Doom II on that same computer.

How can multi-player be ported to <a href="https:&#x2F;&#x2F;dos.zone&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;dos.zone&#x2F;</a> ? WebUDP ??

My first computer was an IBM 486DX@33Mhz. My father had an Apple Macintosh Quatra (Ferrari) and I had this IBM (hooptie). I remember vividly trying to get DOOM to run on it. It would but at 6fps. With the turbo switch on, 66Mhz, I got 12fps on low settings.<p>My father and I tried everything we could to overclock that IBM into 133Mhz but the CPU was holding it back. Later that year, he bought Marathon by Bungie (precursor to Halo) for me on his Mac. I think he felt bad that I was so disappointed. I loved it. He saw this and for Christmas that year, I had a new motherboard with a new Pentium chip capable of ripping Martian marine mutant faces.

Sweet, I can run it on my new book 8088 laptop<p><a href="https:&#x2F;&#x2F;www.aliexpress.com&#x2F;item&#x2F;1005005534146618.html" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.aliexpress.com&#x2F;item&#x2F;1005005534146618.html</a>

I can&#x27;t easily tell; does it still require VGA or MCGA to run?

Does anyone know of any compact Doom wasm examples? Looking for the tiniest Doom that could run in a web browser.

&gt; It&#x27;s based on GBADoom<p>I wonder why. The GBA has a 32-bit ARM processor.

Doom will soon have been ported to more hardware than NetBSD!

It&#x27;s interesting that a not very optimized port of DOOM was available for m68k Macs where DOOM runs at an almost playable framerate on a Mac LC or LC II with 15 MHz m68020 or m68030 on a 16 bit memory bus. It&#x27;s worlds faster than DOOM on a 24 MHz 80286.

Doom ran on the 16 bit SNES console

Maybe I am missing something but are all the wall textures replaced by the door texture?
