Check if you haven't got PulseAudio installed. If you go into the Audio settings in RetroPie - does it show PulseAudio at the top ?

@mitu Sorry, but it seems that I can only edit my posts during a limited time. After some time has passed, the edit option dissappears.

I don't know if it is because I'm a new user or if it is the same for everyone.

RetroPie doesn't have a Doom Legacy package - it's probably something extra included. I don't find any information about the RGB-Pi OS being based on RetroPie (though the documentation has some info that include RetroPie specific paths), nor a source repository for the image - maybe ask the image author about the issue ?

@mitu solution: create a script with the following:
#! / bin / bash
"apulse / opt / retropie / ports / lzdoom / lzdoom" ""

It doesn't work like the other games on the list, but it opens the traditional lzdoom text dialog, the wads should be hosted in ./.config/lzdoom

@ExarKunIv Crikey, just read through that post. It's quite technical but it looks like I may be able to run Doom 3 and a mod after all! Thank you!

rpi 3b+ and retropie 4.6 . I saw ... although I had all the scripts adapted with zdoom ... I would touch to modify them all again.

Fixed it, though I'm not sure what is going on... let me explain.

If you look at my prboom.cfg file you will see this line for my pWAD file.

wadfile_1 "SIGIL.wad"

Now inside of PrBOOM it show the wad file as SIGIL.WAD"

I used my controller and was able to delete the quote symbol off the end and now it works like it was supposed to. The odd thing though is that my prboom.cfg file looks exactly as it did before.

What's that all about?

@InfinityBeing said in Help with Ports:

Why are
these installation pages so barebones?
Why not have an FAQ error section below
the instructions, so people can see common
errors other people have.

1st off the documentation is community maintained, it's nobody's job to update it. Or maybe I should I say it's all of our jobs to update it.

2nd, why do you assume that the issue you have is a common error?

3rd why are you hijacking someone else's thread?

@dalekman27 Good to hear! Enjoy :)

Never mind ..figured out doom 2 tnt and plutonia are all 32 levels in size and share the music file names.

@psyke83

Thank you a ton, your advice worked perfectly for Sigil. I actually am interested in having individual launcher files for Brutal Doom for all of the Doom versions just because I like the simplicity of being able to select each game version separately, even if it is more work. But it isn't working like Sigil did. I created another folder under the doom folder called "brutaldoom," just like with Sigil, then edited the emulators.cfg file with the addition of an emulator called brutaldoom. This new entry had /addon/* changed to brutaldoom/*, the same as I did with Sigil.

I placed the doom wad in that folder, and the brutal doom .pk3 file. I set up a "Brutal Ultimate Doom" launcher directing the location of the doom.wad file in the doom/brutaldoom folder. It launches it perfectly fine when I set "brutaldoom" as the default rom launcher, but for my launcher for the normal Ultimate Doom it will then be set to use the brutaldoom launcher as the default rom emulator as well. If I change the normal ultimate doom launcher back to lzdoom to play vanilla doom, the default emulator for the brutal doom launcher will then automatically be changed to lzdoom as well. So changing the emulator for one ultimate doom launcher changes it for the other, whether its brutal doom or vanilla. I assumed that was because I used the doom.wad file in the brutaldoom folder without changing the name, so what happened to one "doom.wad" changes it for the other because they have the same name, despite being in different folders.

So I tried changing the name of the doom.wad file to brutaldoom.wad in the brutaldoom folder, and kept the original vanilla ultimate doom in the doom folder unchanged, but then it won't even launch the brutal doom version. So it seems to have to keep the original wad name. Since what I did what worked for Sigil I'm lost as to what it is making the two doom.wad files, in different folders, linked. You know so much about how it works, is it obvious where I went wrong? I feel like it must be something small that I just keep missing.

@pamput Yes it does indeed appear to be fixed now

It's not only RetroPie that changed over the years, but also prboom. There's now a core option for the FPS (I think the original Doom ran at 30 or 35FPS), check if yours is set to 60 FPS.
Also, when opening a help topic, please add more info about your system and setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

@TigerMask Support for Sigil in lr-prboom was added on 1 June (see this post) so you will need to update lr-prboom from source.

And oddly enough I am attempting to duplicate all of these steps on my Pi3 setup and I am back to where I began. Except now the WAD Header error has a lot more garbage at the end than ever before.

EDIT: This only reflects the Run Command method.

@Retro_PiGamer
yes you can have both installed and some wads running on one and some on the other.
i have doom 1 and 2 playing with ir-prdoom sinice i have mp3s for the music. and i have hexen and Heretic running on zdoom.
