  • Hey all,

    I've been away from the community for awhile since i lost my pi during the move
    I recently got a new one the 3b+ and im thinking of making another doom distro for it (pretty much just doom wads+source ports)..
    Its litterly been like 5months or more since i did anything with the Pi so my question is
    What changed so far for doom ports? Any updates or new ports??
    Also what source port would give me the best performance??
    Im not really looking into modding doom so no zdoom besides that port is outdated...
    But i do want to play wads vanilla style wads so boom compitble wads..
    Any advise???
    Im sure theres some doomer out there on the pi that can help me?

    Anyways thanks for your time reading this

  • @RetroFreak89 Welcome back. The latest news is that i have successfully gotten Doom Legacy source port to work which is 2 player split-screen.

    This source port is still active in development and it is the latest version that can be compiled on our Raspberry Pi. It also supports custom iwads.

    If you want the most vanilla experience you could try out Chocolatedoom but im not sure if that source port supports boom compatible wads.

  • I don't want to hijack this post but i'm a pretty big doom fan myself.... I remember 10 years or so ago I played a HD version with texture pack and HD demons... do this compare to vanillia? or chocolate?

  • @stevejp1978 i believe if you use zdoom port which is on retropie it has that same hd textures in settings and works fine.. but zdoom is outdated so i want to avoid it

  • @tpo1990 nicee i have no idea how to compile im looking for a source port that gives best performance on the pi and that plays boom wads what do you recommand??
    I only know how to get zdoom and prboom working which bot are outdated engines :(
    I think my best bet might be prboom plus,crispy/chocolate or legacy or mayb zandronum?? But how do you compile so i can try itsorry huge noob here maybe you can paste the commands so i can paste it lol im that big of a noob when it comes to these commands

  • Anyone here that play doom wads? Whats your port of choice?

  • @RetroFreak89 The Doom Legacy port is available for you to install as a scriptmodule, just like you would install zdoom from the RetroPie setup. I have made it so that it is easy to install just download the scriptmodule from my github page.

    You could try Zandronum or GZDoom source port, but that will require you to compile it by your self. I have earlier been successful at compiling both these source ports. From what i can tell, Zandronum seems like the online mulitplayer port of choice and GZDoom seems like an updated ZDoom source port, which its development has picked up after Zdoom has stopped development.

    These are all the ZDoom variants out there:
    ZDoom: Old doom source port. Outdated and . (Used for RetroPie project)
    GZDoom: Primary doom source port. Enhanced OpenGL (Still in development)
    QZDoom: Test source port for implementing new features into its primary source port(For testing purposes)

    Other variant:
    Zandronum: Not Zdoom but previously known as the online multiplayer source port Skulltag.

    For what you seem to be looking for i would think that GZDoom will fit your needs since that one is built on ZDoom and improving. It should also be mentionen that GZDoom can use OpenGL as well. If you want i could probably built a working scriptmodule for testing out on our RetroPie.

  • @stevejp1978 It depends on which Doom Experience you want and what kind of gameplay you like.

    Chocolatedoom is probably the best source port to experience Vanilla Doom.
    Zandronum is probably the best online mulitplayer port to use.
    GZDoom or ZDoom is probably the best Doom source port that supports boom and custom compatible wads.

    I would say that all the doom source ports has their advantages to its own in regarding what kind of features that they offer.

  • @tpo1990 do you remember how well (or badly) GZDoom ran on your Raspi?
    I'm interested about trying it. Can you give me some tips about how to compile it for a 3B+? I barely know how to compile ZDoom and CMake is currently my kryptonite. Any info you can give me is useful.

  • @Protocultor From what i can remember: The first time i tried to compile it i had some troubles. You need to make sure that you install all needed dependencies/packages first before downloading and compiling from source. When compiling from source, it is necessary to know which version to compile since there is an stable, alpha and a old GZDoom 1.8.6.

    After compilation i did change some video settings to make it run as good as ZDoom in the game. GZDoom ran pretty well.

    Since it is just an enhanced ZDoom i think we should be able to run it on our Raspi. I could probably create a working scriptmodule as well for RetroPie just like my other work.

    I used the compile documentation from the official link:

  • @tpo1990 many thanks for all the info!
    I'll try my luck with a newer version of GZDoom, since 1.8.6 is pretty equivalent to what we already have on ZDoom, but it's always good to know that it's possible :) . Cheers!

  • @tpo1990 yes plz do so im so confused on this compiling thing not sure how it all works yet..
    After downloading the file from github what do i do with it??
    Sorry kind of a big noob here

  • Managed to compile different versions of GZDoom, but none of them ran.
    4.0.0 says I don't have OpenGL 3.3 (duh)
    3.4.0 says "failed to load OpenGL functions"; I tried it after I found out it was the last supporting OGL 2.0
    3.1.0 just crashed, and I couldn't get any clue from the log.
    Tried them with different drivers in raspi-config -> advanced, but nothing came out. Maybe it's my Pi (updated constantly), but I'll let someone else try to make it work; I'll get back to old trusty ZDoom.

  • @Protocultor aint nothing wrong with trusty old zdoom. I have like 65 games running on it so i aint complaining.

  • @RetroFreak89

    After downloading the Doom Legacy scriptmodule, it needs to be placed in /home/pi/RetroPie-Setup/scriptmodules/ports/
    and then you should be able to install Doom Legacy the same way as you would install ZDoom from RetroPie Setup.

    No problem, i will help out as much as i can.

  • @Protocultor Where did you try run the GZDoom binary?

    Was it in CLI/Emulationstation or in X11 Window/Raspbian desktop?

    Now that i think of it, it could be that i was able to run GZDoom in Raspbian Desktop which uses the X11 Window and not in Emulationstation.

    When you try to compile from source, sometimes it will be compiled with support for the framebuffer which CLI/Emulationstation uses or not. It could be both Framebuffer/X11 or it could be one of them. Also you might need to change some variables in the makefile in order to make the GZDoom binary able to use Framebuffer or SDL as what ZDoom uses.

    Framebuffer: Is what Emulationstation uses when using runcommand script.
    X11 Window: Is what Raspbian Desktop uses, when using applications in the desktop environment.

    I will try to compile GZDoom on my test Raspi SD card and see if i can get it to work again.

    Might be worth trying to run with +set gl_es 1 to force the GLES SDL renderer for the framebuffer version (see this commit. Otherwise, OpenGL means X11 must be used.

  • @mitu I might look into that when trying to compile GZDoom again on my test Raspi. Thank you Mitu.

  • @tpo1990 now I feel dumb, completely forgot about trying it under X11. Tried it always in CLI, because I want it under Emustation.
    I'm not good with (c)make, and the only option I found was NO_GTK which I enabled (thank gods for ccmake); I assumed it was enough, but didn't make a difference except for the style of the windows it showed when crashed.
    Tested it under desktop and "kind of wanted to start" even creating a window and giving me the creepy sound when Doom 1 starts, but crashed after that.

    +set gl_es 1 did have an effect, 3.4.0 at least showed that it recognized GLES before crashing. Without it, it just exits saying "no OpenGL functions". That's under both CLI and PIXEL.

    If you can make it run under framebuffer, I'd be super grateful.

    Doesn't seem to work under the framebuffer - i.e. via GL ES. It crashes with the same message:

    Unsupported OpenGL version.
    At least OpenGL 3.3 is required to run GZDoom.
    For older versions of OpenGL please download the vintage build of GZDoom.

    In all fairness, I'm using the latest git (4.1).
    I have stumbled upon an previous topic on the GZDoom which might indicate that GLES3 might be needed (
    I guess I'll give the legacy (3.x) branch a try.
