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 Outdated and .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: https://zdoom.org/wiki/Compile_GZDoom_on_Linux
-
@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.
-
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:

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 (https://forum.zdoom.org/viewtopic.php?f=50&t=60873).
I guess I'll give the legacy (3.x) branch a try. -
Now that it comes to mind my, it might have been Zandronum that i was successful at compiling earlier. It certainly works both in X11 and Framebuffer. I was able to compile Zandronum by following the french site framboisepi.fr, but unfortunately it builds an 3.1 alpha version instead of the latest primary version 3.0 in which Windows users uses. I will look into making it build the latest stable version 3.0.
I also came across a reddit topic stating that GZDoom might not be able to work on our RPI due to either poor OpenGL support or performance. Reddit link
Here is another website where someone did manage to change some OpenGL variables in the source files of GZDoom so that it does not rely on OpenGL when compiling. (This might be worth checking out) DRDTeam link
I think our best is Zandronum instead of GZDoom. Zandronum seems to look identical to ZDoom and its other versions but with focus on enhancing multiplayer. It is also one of the following ports that Doomseeker uses to launch into playing online. (Doomseeker is a online multiplayer launcher gui) Zandronum might just be a good alternative over using ZDoom.

Thanks for digging this. From what I gather in that topic is that GLES3 is still required using GL ES (i.e. not using OpenGL). That might work for the systems what support it (like the Odroid XU4 or N2), but for the Raspberry PI the limit is GLES2.

It might seems that we have a reached a hardware limit for our Raspberry Pi, which i therefore think that Zandronum would be our best bet to get working. I did also managed to get Doomseeker working as well in X11 and i could see online servers but unfortunately they were using Zandronum v3.0. If we could get that working as well it would make Online multiplayer in Doom a reality on our Raspberry Pi.
I tried yesterday with compiling QZDoom which is ZDoom's test base and it also asks for OpenGL when trying to launch the binary just like GZDoom does.

Yes i know about ReMooD and Edward850's BananaSplit Fork of Eternity.
While i was planning to make split-screen Doom a reality for Raspberry Pi, i did try to compile ReMooD and was succesful at some point making it work with some small bugs in X11. (this was in RetroPie 4.3 Jessie last year) and now i have already tried with compiling it recently which i failed. Since Doom Legacys latest version, the source port is more stable and it works great.
I have also managed to succesfully compile BananaSplit before and that source port is the fastest Doom source port that i have ever tried on my Raspberry Pi 3. That fork has 2 player split-screen but i could not get it to work, since it would just throw segfault error. Only singleplayer works. I even think it runs better than ZDoom according to my own opinion.
