How to restore original assets when loading SIGIL 1 & 2

[prometh]

Loading Doom and Ultimate Doom with either or both Sigil episodes will replace the original title and credits graphics, the title music and the "intermission" (end-of-level score) music even when playing the classic episodes. This can be corrected, but so far only for GZDoom completely.

1. Download and install Slade.
2. Using Slade, open the WAD file for whichever Sigil. I chose to modify:
   • SIGIL_v1_21.wad
   • SIGIL_SHREDS.wad
   • SIGIL_II_V1_0.WAD
   • SIGIL_II_MP3_V1_0.WAD
3. Remove CREDIT (graphic) lump.
4. Remove D_INTRO (music) lump.
5. Rename D_INTER (music) lump to D_E5IN (for Sigil 1) or D_E6IN (for Sigil 2).
6. Add intermusic = "D_E5IN" (for Sigil 1) or intermusic = "D_E6IN" (for Sigil 2) to each/every map block within the ZMAPINFO lump.
   Before:

   Code: Select all

   map E5M1 "$HUSTR_E5M1"
   {
   	levelnum = 41
   	titlepatch = "WILV40"
   	next = "E5M2"
   	music = "D_E5M1"
   }
   

   After:

   Code: Select all

   map E5M1 "$HUSTR_E5M1"
   {
   	levelnum = 41
   	titlepatch = "WILV40"
   	next = "E5M2"
   	music = "D_E5M1"
   	intermusic = "D_E5IN"
   }
   

7. Save each file you edit.

Note: There are no CREDIT or ZMAPINFO lumps within SIGIL_SHREDS.wad.
