Doom128/Heretic128/Hexen128/Strife128: Gibbon's ultimate vanilla source mods for DOS

[Redneckerz]

Introduction:

(Approved by @Gibbon and @OpenRift)

@Doomkid please take note for your Vanilla threads!

Inspired by @nukeykt and @NY00123's works on gamesrc-ver-recreation:

Sir Gibbon of England started his quest for more, better. He came across the tales of executable hacks and source modifications, and wondered, where the pot of source gold would be lying.

 

Later, in a dream, NY00123 and Nukeykt came to him.They told him: ''Create the ultimate DOS based modification, Gibbon! The community of Doom needs it!''

 

So Sir Gibbon woke up the next morning, brought himself a typical English Breakfast together with Coco the Caco, his pet demon, and he set to work.

 

The result: Doom128, Heretic128, and Hexen128.

EDIT 29-4-2022: Now also with Strife128!

 

Features:

All 128-series source modifications take Doom32's limits as a basis - Itself derived from Doom2-plus. But the 128-series goes way, way beyond. The Doom32 limits are multipled by a factor of 16. This means hugely detailed and large limit-removing WADS are possible in DOS. Back to Saturn X works considerably well.

• In general, the limits are as follows:

limit                         : old    * k   = new
-------------------------------------------------------
visplanes[MAXVISPLANES]       : 1024   * 16  = 16384
drawsegs[MAXDRAWSEGS]         : 2048   * 16  = 32768
SAVEGAMESIZE                  : 2883584 * 16 = 46137344
activeplats[MAXPLATS]         : 7680   * 16  = 122880
vissprites[MAXVISSPRITE]      : 1024   * 16  = 16384
linespeciallist[MAXLINEANIMS] : 16384  * 16  = 262144
openings[MAXOPENINGS]         : 200 * 256 * 16  = 819200

* {{c|MAXOPENINGS}} relies on the {{c|SCREENWIDTH}} constant, which is 200 (from a 320x200 screen, which is what is used in Vanilla Doom
* Heretic128's SAVEGAMESIZE differs depending on the version of the executable used.

 

• Executables are built against:
  • Doom128: Ultimate Doom 1.9, Doom 2 1.9 and Final Doom Anthology
  • Heretic128: Heretic 1.0, Heretic 1.3 (Shadow of the Serpent Riders version)
  • Hexen128: Hexen 1.1 Late
  • Strife128: Strife 1.0

Limitations:

• DeHacked is currently not working on Doom128 (Neither are HHE files for Heretic128).

This is quite awesome,  A good reason to turn on my old super socket 7 machine to test them out. 👍

It should probably be packaged with DOS32A.EXE, renamed DOS4GW.EXE, because it won't run without it. Although upon exit I get a warning that "real mode interrupt vector has been modified: INT 00h"

Issue with that is it would also need to be packaged with a dosbox config file because it needs 32MB of memory to run too.

 

Ill add the info to the readme.  I was assuming everyone had DOS4GW anyway, I'll add it to the packages.

 

I don't get any such warning.  What's your dosbox config?

Is there any specific relevant information you're looking for? The whole config file?

That would help yes, the whole thing.

 

Most of the time, one small setting can have huge effects on dosbox.

Appreciated. I had to gobble up an exe from the attic. Perhapa DOS32A is even better.

 

Silly question, but stock Doom exes do not need any auxillary progs - can something be integrated?

You also added DPMI to your autoexec - perhaps you can write an ideal-config template for DOSBox?

[NY00123]

Renaming DOS32A.EXE to DOS4GW.EXE looks like a common approach for running older exes (which lack sources), so this might work here; Albeit I thought that the usage of the name of DOS4GW.EXE for what is actually DOS/32 can be confusing.

 

I'm not entirely sure if this is allowed by DOS/32's license in this case, but another option might be to bind DOS/32 into the game exes. Given that it's intended for use with older EXEs from the 90s in general, it might be.

[Gibbon]

Good point, I had it from DJGPP and WATCOM (exe date is 1993) so whatever the licence is..  no idea.  It is a bit ambiguous at this stage and I just zip and up throw around watcom's DOS4GW.EXE

This is amazing stuff.

 

It would be great to eventually support loading deh patches natively, since DeHackEd doesn't recognize this EXE.

Work is on the way to have a 128-series compatible version going on aswell. (Or well, one that supports gamesrc-ver-recreation.)

 

If that works, then i suppose a new iteration of Chocorenderlimits is in order? ;)

 

As for native DEH support: @Gibbon now that would be an absolute killer feature for a vanilla engine.

[Gibbon]

Indeed it would and yes I probably will add Deh support as well as make sure that dehacked will work with it.

 

Of course there are also other things that need tackling to make as many features from DOOM32 added into this one..  SIGIL support, Medusa effect fixes (this will compliment the tutti fixes), merging deh files to make standalone exe's etc..

 

Since all my stuff are 'lone wolf' projects, it's added to my bucket list.

 

Also, the 4-clause BSD licence is not GPL compatible so that's a no on any form of merging.  4-Clause BSD isn't a free or open source software licence at all.

So it will stay as a standalone binary and just plop it into your dosbox.

While the license is a bit different, it indeed has its own variation of the advertising clause. Here's a copy of the 4-clause BSD license for reference: https://spdx.org/licenses/BSD-4-Clause.html

 

Since the built exe can work without binding or even using DOS/32, I'm not sure that binding DOS/32 will be considered the creation of "derivative work" as defined in the GPL. There are also the original non-GPL terms by which the Doom, Heretic and Hexen sources were originally distributed, albeit Heretic and Hexen's terms were an EULA not intended for the distribution of source code. Either way, as usual, it should better be assumed that IANAL.

It isn't so much the derivative work that's the problem.  It is the additional restriction that the 4th clause brings.  GPL prohibits any additional restrictions on usage, but the 4th clause brings that additional restriction.

 

As for the DEH integration, I think I can take the code from BOOM and modify it for Watcom.  Since BOOMs version is fairly simplistic and plugs in nicely to a mostly vanilla'ish codebase.

Also, how much bug fixing would be "allowed" so to speak? Really I just think it'd be great to be able to load sprites and flats the normal way -- so DOSBox users don't have to use DeuSF.

Pretty much everything DOOM32 has plus Tutti and Medusa fixing.

I'm currently waiting for further development on 128 before I do any more work on Dehacked128, namely once the medusa effect is fixed.

Yes, this is indeed the clause that makes the original 4-clause BSD license incompatible with the GNU GPL.

 

A big question is which combinations are still allowed by the GPL, if any. For example, there are instances in which a GPLed program is allowed to be linked with a proprietary system library. For more details, the contents of the relevant GPL document should be inspected. https://www.gnu.org/licenses/gpl-faq.en.html#SystemLibraryException

This clearly sounds like a useful approach for the user. Once the relevant parser from another source port is added, some amount of work might be required for replacing hardcoded contents like strings. Hopefully, there won't be as much work for the arrays defined in INFO.C, because there aren't that many of them. Maybe function pointers will need more work for going through them.

All have been updated to implement NOVERT.  All these builds will no longer have the annoying vertical mouse movement and users will not need any silly third-party software to implement that.

 

It is now actually playable :)

Super epic stuff Gib. When i get back from holiday ill update accordingly.

 

By the way, did you look into adapting Boom code to Watcom to get DEH integration going?

 

Secondly: i can't check, but the medusa effect was fixed?

 

@OpenRift if Medusa is fixed, perhaps now the time is right for Dehacked128?

[Gibbon]

Medusa isn't 100% fixed.  There are still some instances of them which I'm trying to squash, there are a few differences between this codebase and say..  Inter-Doom DOS, so I can't just copy things in.  Largely it is a 'compare and fix' approach, what, with my...  11 projects?  It goes a little slower than I'd like :P

 

Dehacked will come, but that will take quite the effort since it literally alters everything.

[Gibbon]

I guess @Redneckerz should change the title as we now have a STRIFE128 too.

 

Here: https://github.com/atsb/STRIFE128/releases/tag/v042022.1

 

I did this as there are not too many DOS Strife source ports, and I needed another source port apart from vanilla Strife for something that Myself and OpenRift are working on.  So voila, enjoy kicking the Order's butt!  Again all credits to NY00123 and co are there.

Wonderful.

 

There goes my weekend.

 

Ill see if i can get this (and ZZDoom/RZDoom) done by the weekend. Its time for a write-a-ton again.

[Lippeth]

I spent a bit of time messing around with these in various DOSBox forks and have concluded that a list of recommended config settings could be helpful. If there's a readme I couldn't find it, and I also had never heard of DOS4GW until today, if that helps to paint a better picture of my DOS ignorance (and probably in general too).

 

Ultimate Doom seems to hang for me when trying to start the game:

Spoiler

 

Heretic and Hexen work great, though I actually prefer vertical mouse movement in Hexen for whatever reason, unless playing as the mage. Doom 2 works, though the mouse bind to move forward and use doesn't seem to work. I haven't yet tried Strife.

 

This one took a few tries to figure out, but if an active sound device uses irq 5 in the config file, sounds echo infinitely, like something else is also using it.

 

My own personal problems aside, I do enjoy playing random wads without the fear of going deaf when saving, so great work!

How do you run this? Does this need just the WAD or does it use the entirety of the original executable?

Same as Doom.  You need the exe and the iwad.  You do however also need DOS4GW which is provided in the download as my increased limits push it over into extended DOS mode as a requirement :)

[Redneckerz]

Strife128 is now on the Wiki.

[Gibbon]

Thanks @Redneckerz!

 

While it is slightly related, I forked the id-setup program and made three rebranded (and prettier) setup utilities for DOOM128, DOOM128 (DOOM2) and HERETIC128.

All will look for the relevant executable.  More TURBO C goodness.

Edit: I re-enabled the assembler code to add the 'funky blue' back.  Because I'm a dirty filthy purist :D
