Cannot control WAD load sequence

[Starman99x]

Some mods require loading multiple wads in the correct sequence, for example:

SCYTHE.WAD D4V.WAD D4V.deh

SCYTHE.WAD D4V.wad FSCYTHE.WAD D4V.deh

SIGIL_V1_21.wad SIGIL_SHREDS.wad

The core seems to reverse this order or ignore it, even if specified correctly in prboom.cfg :

wadfile_1                 "SCYTHE.WAD"
wadfile_2                 "D4V.wad"
dehfile_1                 "D4V.deh"

This results in loading DOOM2.WAD without the mod even with prboom.cfg or DOOM2.prboom.cfg present in the same directory.

Loading D4V.wad directly does work, but the custom maps like SCYTHE.WAD do not work no matter what you try in prboom.cfg.
