DOOM to Heretic conversion pack and resource pack [V 1.25]

[i2van]

Tested it. It seems to work fully functional. Good job . I had to tell my idiot virus scanner that the file is safe, but not much you can do about that on your end.

Thank you!

I suggest re-downloading it if you use x64 version - I did some x64 pointer arithmetic fixes.

Do you use GFXMAKER? Looks like it requires more porting efforts than MD2CONV.

No, all you need is DM2Conv to manually convert a DOOM level (so long as the level didn't include any custom textures or objects). However you need to use the custom RSP file included with my mod's package (MTOConv.rsp).

The command line used would look like this:
dm2conv input.wad output.wad @MTOConv:D2TOH

Unless you used a DOOM1 level in which case you would use DTOH instead of D2TOH. Also you would need to rename the level's name for DOOM2 levels in editor like Slade (For example MAP01 gets turned into E1M1 thus would need to be manually renamed back).

The main advantages over just using the top loader method is that manually converted stages don't need the toploader wad, thus you can play them and vanilla Heretic at the same time. Also manually converted stages can be edited after being converted, unlike the the toploader method which does not actually alter the DOOM wads in any manner.

Ported GFXMAKER.

Excellent mod, I will finally be to play better the DOOM maps with Heretic.

But by any chance, you won't have a version or patch so that DOOM monsters are reemplaced by Heretic vanilla monsters?
(Former Humans should been reemplaced by golems and the Lost Souls by Gargoyles)

Also the Super Shotgun should be reemplaced by Crossbow (Like in Samsara) Instead the Super Crossbow, The default shotgun by Mace and the BFG9000 by The Tome of Power.

I was having a good time also with HeXeReTiC Fantasy mod.

+ Linux port.

I've already run into two potential balancing bugs: 1) on every difficulty, zombie guys are replaced with Disciples of D'Sparil, which are way tankier and more powerful; and 2) shotgun guys are replaced with Maulotaurs
Is this something I'm doing wrong on my end, or can someone else recreate?

My method for loading the game in case it gives more info: using DoomLauncher -> renamed Doom.wad because DoomLauncher doesn't allow duplicates -> using Heretic as iwad and GZDoom as port, loading renamedDoom.wad first, then MTOBase second, then MTOTopLoad third. Is there something about any of this that would strangely mismatch enemy loading?

Strange, it sounds like the Topload wad isn't working for you (Maulotaurs use the same spawn ID in vanilla Heretic as shotgunners use in vanilla DOOM. The main thing the toploader wad does is corrects the spawn IDs). Did you spell the toploader wad's filename correctly?

Are Shotgun Guys supposed to be the Hexen 2 archers? Because if so, apparently I just needed to update DoomLauncher...no idea what DoomLauncher is doing with the toploader now vs what it was doing before, but that seems to have fixed it. And also, I guess the Disciples weren't replacing zombie guys, but were replacing DoomGuy corpses or something, which I'm assuming also share the same spawnid? Anyways, hah, glad to have worked that out. I'll come back again if I notice something else off, thanks for the attempted help though MObreck! It was just user error, doh!

Yeah, the shotgunners will get replaced with archers or green golems, depending on what seed the randomizer draws from the level you are playing. There are actually two archer types that can be chosen: one type that shoots a projectile spread that impersonates the shotgunner's attack and one type that shoots a single big arrow.

Looking it up the Disiciples do indeed use the same ID as one of the marine corpses in DOOM. That would make more sense, being the zombiemen use an ID that isn't used in Heretic, thus would be replaced by the not found symbol objects (or crash the game outright in vanilla DOOM).

DOOM and Heretic's IDs don't match up well at all, getting some pretty insane results as you found out. For example if you try to load an unaltered Heretic level in DOOM all the gargoyles get swapped with revenants

[spforce]

can someone write the load order to do for this some example?

Use Heretic as your base game.

Load order:
- DOOM level wad you wish to convert
- MTOBase.pk3
- MTOToploader.wad

I ran into another error that I hope isn't something I did wrong again, haha. After beating e2m4, it gave an intermission screen oddly and brought me to e2m5, but the name of the map was listed as "The Catacombs" instead of "Command Center." Every other Doom map has the original Doom mapname and I'm pretty sure there's no intermission between e2m4 and e2m5 in ultimate doom, or is my memory off?

BTW, this is a nifty and creative little mod you have here, I'm enjoying it! =)

EDIT: also, finishing secret lvl e3m9 brings you to e3m5 instead of e3m7 and finishing the last boss on e3m8 doesn't beat the lvl

This is a really cool idea. I wish there was way to play this with wads that don't use stock textures. It would be neat to tool around something like Episode 2 of BTSX ( https://www.doomworld.com/forum/topic/69960-back-to-saturn-x-episode-2-is-out-of-beta-v101-aug-13-2020/ ) as Corvus.
