Loading Doom PWADs using lr-prboom

backstander

I have a Raspberry Pi 3 running RetroPie 4.0.4

I know how to do this with ZDoom but I was wondering if there is a way to load an PWAD for either Doom or Doom 2.

Here's an PWAD I was going to use for testing.
The Classic Episode for Doom 1 (E2M1 -> E2M9):
https://www.doomworld.com/idgames/levels/doom/a-c/class_ep

I placed both my doom.wad and this class_ep.wad in the ~/RetroPie/roms/ports/doom/ folder.

Here's is my script file ~/RetroPie/roms/ports/The Classic Episode.sh:

#!/bin/bash
/opt/retropie/supplementary/runcommand/runcommand.sh 0 "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-prboom/prboom_libretro.so --config /opt/retropie/configs/ports/doom/retroarch.cfg /home/pi/RetroPie/roms/ports/doom/doom.wad" "lr-prboom"

And this is as far as I've got! In ZDoom you would add something like -file /home/pi/RetroPie/roms/ports/doom/class_ep.wad but I've tried added to this script but it doesn't work.

@backstander The Classic Episode is a PWAD so you can try the method outlined in the wiki.

Thanks @dudleydes
I updated my original post to say "PWAD" instead of "IWAD" so I didn't look like an idiot haha

I think the wiki page is out dated because it refers to /opt/retropie/configs/doom/ when mine actually has /opt/retropie/configs/ports/doom/ instead. Maybe someone should update that :-)

Here's what I did (hopefully no typos):

mkdir ~/RetroPie/roms/ports/doom/class_ep
unzip class_ep.zip -d ~/RetroPie/roms/ports/doom/class_ep
ln -s ~/RetroPie/roms/ports/doom/prboom.wad ~/RetroPie/roms/ports/doom/class_ep/prboom.wad
ln -s ~/RetroPie/roms/ports/doom/doom.wad ~/RetroPie/roms/ports/doom/class_ep/doom.wad
cp ~/RetroPie/roms/ports/doom/prboom.cfg ~/RetroPie/roms/ports/doom/class_ep/
nano ~/RetroPie/roms/ports/doom/class_ep/prboom.cfg

# Files
wadfile_1                 "Class_Ep.wad"

nano ~/RetroPie/roms/ports/The\ Classic\ Episode.sh

#!/bin/bash
/opt/retropie/supplementary/runcommand/runcommand.sh 0 "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-prboom/prboom_libretro.so --config /opt/retropie/configs/ports/doom/retroarch.cfg /home/pi/RetroPie/roms/ports/doom/class_ep/doom.wad" "lr-prboom"

chmod +x ~/RetroPie/roms/ports/The\ Classic\ Episode.sh

Then I restarted EmulationStation
Ports -> The Classic Episode -> New Game -> The Shores of Hell
