Doom is 4196KB.

That's pretty crazy



sort by: page size:

To put it into perspective, that's larger than the entire post-install size of the original DOOM PC video game, including all sound and artwork.

Yes. I remember that too. I edited it to 4 mb just before you responded.

The point is you can't run doom on hundreds of bytes or even several kilobytes or in 8 bit microcontroller.


Wow, that level is _massive_. I wonder what the system requirements are on that. Doom played perfectly on a 486/66 with 4MB. Like how many linedefs are in that thing...

DOOM2.WAD has always been my measuring stick for software size, as I remember how frustrating it was to download such a huge file (15MB!) in the dial-up days. I never did get it to complete - I couldn't justify to my parents that the phone line would be busy for a whole day :)

doom was 52KLOC of C.

You just linked to a 3.5 MB web page. That's more than the complete Shareware DOOM

Doom actually ran at 320x200

Good points regardless though.


Doom only needed 4MB of RAM.

128 Doom demos, obvs.

Apropos to nothing, 7000 is also the number of platforms Doom runs on.

The original Doom was under 50,000 lines of code.

I just spent the last couple of nights watching Doom II playthroughs on Youtube and now this shows up on HN. Sweet!

I still have the (unfinished) wad I created back in the late 90s using WADED from the Tricks of the Doom Programming Gurus. Barely rescued it from a floppy disk over a decade ago that reported the file size as over a gig. Now that I think about it, I hope the CD I recorded to is still good.


Not to take away from your point, but Doom was actually written on a NeXTstation and cross-compiled for PCs, so at a minimum they were using 1120x832 resolution (2 bit greyscale).

Holy shit, you can install and play Doom.

Doom used DPMI. 32-bit, flat address space. All the stupid bs about "you need this much memory below 640k" just went away.

doom had a bigger installed base than windows 95. you sir are gravely wrong.

The only thing more impressive than Doom being run on everything is how increasingly tiny the computer you need to do is.

Doom does not run on 64 bytes of RAM.

Original system regs were 8 MB RAM. You can run it on 4 MB and can shave off some more but you need 16-bit bus ~MB's of RAM to run it.


If you create a model with this code and save it to disk, it will indeed be 14GB. It will be random weights -- the contents won't be there -- but it will be 14GB.

If you use only what is open-source about Doom, you will have an unplayable game.

If you use only what is open-source about Mistral, you will have an ineffective model.

It's not nothing.
