Doom source port family tree

[Lorenzo]

Is there somewhere a complete Doom Source Port Family Tree, with all the source port ever created?

Lorenzo

[DooMAD]

There's a nice list here, but it's not very tree shaped.

[Lorenzo]

Thank you!

Well, I think I will have to do it !!!

A Slightly Condensed Overview of Doom source ports, part of Doomworld's 10 Years of Doom celebration, offers just that.

[DaniJ]

Actually that genealogy chart ins't correct for Doomsday.

jHexen was based on Hexen obviously but jDoom was based on the Linux Doom v1.10.
Both sources were then used to create Doomsday.

[Quasar]

My bad ;) There are a few mistakes in there because I wasn't able to find as much info on some of the ports as I had hoped. And then there was confusion between some of what I did find as well. People gave me conflicting reports on zdoomgl, so I'm pretty sure it's messed up too.

Hello !
I made a little Genealogy Tree. You can download it from my website:

djb.doomwadstation.com

it is in .doc format, but it is not yet complete - Once completed i'll put it in htm form.

Please help me completing it !!

[Graf Zahl]

A correction: Strife descended from Doom v1.666 or later, not 1.2.

[Lorenzo]

Thank you.

There are still some source port i don't know where they are from.
They are:

ATB DOOM
Doom Plus
Doom3D
IAS DOOM
NTDoom
MultDoom
WDMP
Win32 Doom
Windoom
glDoom
MidDoom
PDoom

And I have doubts on ZDOOM. Is it based on DosDooM or on ATB DooM ?

Lorenzo

[TheDarkArchon]

It's based on Linux DooM 1.10

[Nautilus]

Don't forget to add Eternity and Chocolate Doom to the list of ports you still need to add.

[Lorenzo]

Ok, thank you all!
But I have a problem.
The "original source code released by ID" is the one from:
-Final Doom 1.9
-Linux port of DooM
-the one used in DosDooM ?

It's not very clear to me!

As you'll see if you read this, they actually gave the Boom team a different version from the one made public:

Lee Killough said:
The Boom team was given the original Doom sources under DOS from John Carmack, not just the LinuxDoom sources (which had been stripped of proprietary sound code, among other things).

[Quasar]

That being said, however, BOOM was still primarily based on the Linux DOOM source (or Chi Hoang's port of it, to be precise). This is evident in the number of bugs from it which are fixed with explicit comments (mostly by Jim Flynn), AND in the number of bugs from it which were NOT fixed by virtue of them being unrecognized.

I updated my site with a new version of my DooM Engine Genealogy & DooM Source Port Family Tree.

My site is
djb.doomwadstation.com

There is also an interesting BFG page.

Can someone tell me where is Chex Quest from? I mean Doom v1.2 or 1.666 etc..

Thank you for the genealogy.

I have to report a small error:

GZDoom is based on the ZDoom community build, not ZDoom directly.

Also, what about secondary influences. There should be a lot of these as well.

[Lorenzo]

I've updated my site with a new version of my Genealogy.
Now it is in .xls and contain the port's authors.

You can download it from
djb.doomwadstation.com

I update my BFG page too.

gzdoom is no longer based on the comminity zdoom build

it now uses the current in development code released by randy (AKA zdoom 2.0.99)

But it is still derived from 2.0.96x. It doesn't matter that ZDoom incorporated most of the code. That would only make ZDoom 2.0.99 another child of the community build but it doesn't change the original relations.

[Xtife]

true :)

fyi you also missed jheretic in the list
and i dont think ultimate doom came from doom 2 did it? there both different

[DaniJ]

Any chance of an online version of the family tree (you could use Excel's save to webpage but I've heard it generates pretty crappy html)?

[Lorenzo]

Unluckly the save as web page of excel is a true XXXXX
So i think i'll let it in xls form

And thank you all for the suggestions!

Lorenzo

[Xtife]

ya, it should go doom 1.2 ----> doom 1.666 and doom2 1.666 ----> doom 1.9 (----> ultimate doom) and doom2 1.9 ----> doom95

DooM, registered version (three episodes) v. 1.9 is identical with DooM2 v. 1.9. It's also the same executable in the v.1.9 DOS shareware version.

In case theres anyone here who doesn't have Excel - http://www.file-converters.net/product.html

Theres a free demo and it does a decent job of the conversion.

[CODOR]

OpenOffice seems to load it just fine, too.

I'd like to see the genealogy expanded to something similar to the UNIX Timeline, which also lists links for compatibilities and not just source code inheritance. So not only would GZDoom descend from ZDoom, but also Doom Legacy (among others). This would probably require a lot more research, especially as the various ports borrow ideas from each other...

[Quasar]

Yes. For example, Eternity would connect to Legacy, PrBoom, and zdoom even though it is not descended from any of them.

[VinceDSS]

maybe a few corrections to add...

1 - If I remember correctly the DOS exe sources were never released. So it's impossible for chocolate doom to come from doom2.exe v1.9. You better ask fraggle about it :)
The only twist I know about this story is that Team TNT may have got a copy of the DOS exe sources for the development of Boom. Although I am not completely sure.

2 - Heretic was based on doom v1.1, I believe

3 - zdaemon was 1st born out of csDoom and then they implemented new zDoom's features...

[Lorenzo]

thank you!

Is there a amiga-doom expert here around?
i'd like to add the amiga ports for doom (there are a lot) but i don't know where to begin!
