Doomsday Engine

Indeed, it appears the Doom2 wad included with the BFG edition is derived from the XBLA Iwad rather than the PC wad.

• No titlepic lump. Obviously this one will produce a fatal crash in Dday.

• Wolf3D textures with Nazi symbols have been replaced duplicates of textures without Nazi symbols. For instance, the WOLF2 patch lump featuring Nazi symbols has been removed and the texture definition for ZZWOLF2 that originally pointed at it, has been made to use WOLF1 instead)

• Map31 and 32 have been edited to replace SS Guards with Zombie men.

• The SS Guard sprites have been removed; the SS Guard sounds still exist though.

• Map31 and 32 have been renamed 'IDKFA' and 'Keen' respectively.

• The secret exit linedef on Map02 is still present. Obviously, without proper coding behind the scences, this will take the player back to the start of the last level they started from an intermission screen (or Map01 otherwise).

• The XBLA exclusive Map33 that the above secret exit line took the player to on said port, is present in the Iwad.

• The Med Kit, Stim Pack and Berserk packs have had their sprites altered to remove the Red Crosses and instead feature pill symbols.

• A new quit dialog has been added for the BFG edition, for which new lumps have been added to the Iwad for.

http://doomwiki.org/wiki/Doom_3:_BFG_Edition

This page contains a comprehensive list of changes to Doom1 and Doom2 in the BFG Edition versus Vanilla Doom.

Importantly, it should be noted that there are map differences on Map02, Map31 and 32 of Doom2 BFG and that Doom2 BFG also features a Map33, meaning multiplayer between BFG and non BFG users will run into difficulties.

More play testing should be done before this issue is closed.

I did some testing of Doom 2 BFG. I played for about half an hour an noticed only one minor thing. There is a secret exit in MAP02 (see https://www.youtube.com/watch?v=NH3hMAVCzeQ) which should lead to MAP33 but (in the build winx64 2872) send the player to MAP03. I managed to fix that by editing doom2.mapinfo in the following way:

map MAP02 lookup HUSTR_2
next MAP03
secretnext MAP33
warptrans 2
sky1 SKY1 0
par 90
music D_STALKS
titlepatch CWILV01

.
.
.

map MAP33 "Betray"
next MAP03
warptrans 33
sky1 SKY3 0
par 120
music D_READ_M
titlepatch CWILV32

It seems that the above change can be made permanent in doomsday builds, since it should not mess up the standard doom 2 episode.

Thanks for the MAPINFO update, I've included it in the next build of 2.1.

In fact BFG edition of Doom 2 has names of maps 31 and 32 changed (to "Keen" and "IDKFA"). It seems it will be better to create a separate mapinfo filie (doom2bfg.mapinfo) containing everything from doom2.mapinfo and with the following changes

map MAP02 lookup HUSTR_2
next MAP03
secretnext MAP33
warptrans 2
sky1 SKY1 0
par 90
music D_STALKS
titlepatch CWILV01

.
.
.

map MAP31 lookup HUSTR_31b
next MAP16
secretnext MAP32
warptrans 31
sky1 SKY3 0
par 120
music D_EVIL
titlepatch CWILV30

map MAP32 lookup HUSTR_32b
next MAP16
warptrans 32
sky1 SKY3 0
par 30
music D_ULTIMA
titlepatch CWILV31

map MAP33 HUSTR_33
next MAP03
warptrans 33
sky1 SKY3 0
par 120
music D_READ_M
titlepatch CWILV32

and add the following definitions to the defs\jdomm\text.ded file

Text {
ID = "HUSTR_31b";
Text = "Map 31: IDKFA";
}

Text {
ID = "HUSTR_32b";
Text = "Map 32: Keen";
}

Text {
ID = "HUSTR_33";
Text = "Map 33: Betray";
}

I've already recently added such a .mapinfo file: https://tracker.dengine.net/projects/deng/repository/revisions/bfad5c63f987ac470ae1072fd3890aacebd385f7/entry/doomsday/apps/plugins/doom/data/doom2-bfg.mapinfo

I can change the names of maps 31 and 32 as well for the BFG edition.

I have created a pull request to incorporate the above changes to master

Merged.

It seems that the No Rest for the Living finale text should be added somewhere - see C6TEXT from https://github.com/superna9999/prboom-plus/blob/master/data/lumps/nervebex.lmp

According to Doom Wiki, the Doom II endgame comes after map 8, so I added that in addition to the finale text.

In No Rest for the Living before map07 text C1TEXT (see file defs\jdoom\doom2\finales.ded line 95) from Doom 2 appears. It should not appear.

I have just created a pull request to fix the above.

Thanks!
