Playing vanilla .DEH-based wads / mods (DeHackEd) in DosBox

This is the easiest, fastest way to play .DEH-based Doom wads and mods in DosBox (or real DOS) as of late 2022. I figured I'd share this as a quick, simple and straightforward guide.

1) Download this .zip file: https://doomshack.org/uploads/DeHackEd_2020.zip

2) Place a DEH file (and its accompanying WAD file) in your Doom / Doom2 folder.

3) Copy CWSDPMI.EXE, DEHACKED.EXE, DEHPICK.EXE, DEHMAKE.BAT and DOOM(2).EXE to your Doom(2) folder.

4) Now, run DEHMAKE.BAT. Press Y when "Do you want to do this?" shows up. This will generate an EXE with the same name as the .DEH file.

5) To play, simply type:

NAME.EXE -file NAME.WAD, replacing "NAME" with the actual names (duh).

If multiple DEH files are present, DEHPICK will bring you to an easy-to-understand selection menu.

------------------------------------------------------

UDOOM32.EXE and DOOM32.EXE are included in this zip, renamed to DOOM.EXE and DOOM2.EXE respectively.

For playing wads and mods, I recommend replacing the default DOOM and DOOM2 EXEs with these, keeping the old versions in a different folder as backups.

These programs raise the "visplane limit" as well as other tight limits that often crash the default EXEs.

------------------------------------------------------

DEUSF.EXE allows you to merge the sprites/flats from DOOM(2) into your pwad, thus avoiding crashes. If you try to play a wad but Doom hangs at "Playloop State", it likely means the wad needs appending with DEUSF.

Copy DEUSF.EXE to your DOOM/DOOM2 directory and type "deusf -app mymod.wad" (inserting the actual name, of course). This will inflate the wad and make it completely vanilla compatible.
