ZDoom

Well you can change iwad info in zdoom.pk3 but i dont think is legal.

Fixed. I also noticed the status bar border was missing in the shareware as well.

But surely you realize that the horrifying menace of the Snake was reserved only for the third episode!

I'm guessing design docs from pre-1.4 were never updated, and that bit of advice just passed into general use without really being needed any more.

Well, Heretic was forked from Doom 1.2, did Raven ever add that restriction themselves?

It's just my opinion, but I think ZDoom should spawn Maulotaurs (sans sprites!) at the missing object spots. :twisted:

[quote="Gez"]Looks like you had to use a weredragon or ophidian to make the level error out in vanilla shareware.[/quote]What about registered version textures?

(I like how the crappy Firemace system requires yet another special case. :? )

[quote="NeuralStunner"]Weird. Back when I first started mapping for Heretic, I got the impression that I should use commercial-only objects (I tended to use Chaos Devices) so shareware (vanilla) Heretic couldn't run them. Does that kind of approach only work with DOOM.EXE?[/quote]
I don't know the answer to your question [edit: though it looks like Gez has that covered] but, purely for the sake of background information, I do know that this approach used to be one of the recommended ways of complying with id's wishes that PWADs should not run with the shareware version of Doom. That was with relatively early versions of Doom before id hard coded the shareware version to not run with the -file parameter. Once that was done (in version 1.4 I think), it was less important.

Too bad for you then that the internal names are much more relevant to use than the fancy names when the objects in question are discussed in a technical thread about software issues. :p

Vanilla Doom cannot run mods in shareware, either, so said approach also isn't needed for vanilla shareware.

Weird. Back when I first started mapping for Heretic, I got the impression that I should use commercial-only objects (I tended to use Chaos Devices) so shareware (vanilla) Heretic couldn't run them. Does that kind of approach only work with DOOM.EXE?

How can it?
Easy solution: When playing shareware, skip the message and the exclamation marks. More isn't necessary because you can't load mods with shareware IWADs.

Found that a NOTSHAREWARE flag for thingtypes is needed due to Heretic using
unmodified commercial-version maps in its shareware IWAD, which during
mutiplayer spawn items not normally in the episode. In Heretic, these were
hacked out by doomednum in P_SpawnMapThing (disgusting). In Eternity, we'll
just use a flag to control it.

ZDoom uses the presence of sprites in the IWAD to control such things, but that
isn't satisfactory to me for various reasons; ie, those objects STILL shouldn't
be available in shareware, even if somebody hacks in their sprites.

Seems Heretic had a mechanism not to spawn unavailable items. I saw this while reading [url=http://mancubus.net/svn/eternity/trunk/haleyjd_changelog_6.txt]Eternity's latest changelog[/url]:

Looks like the "sprite available Y/N?" system doesn't actually handle this case.

Start a deathmatch game on E1M1 of heretic1.wad. The map will be full of <!> missing frame icons from Phoenix and Skull Rods and ammo that are flagged multiplayer.
