Doom Legacy - Doom Split-screen Source port

ish

Hi im fairly new to the Linux and the rpi and don't understand the build process of the doom legacy application can you please explain to me how you compile it. Sorry if I sound like a big noob @tpo1990 @Solid-One

quicksilver

@ish Did you look at the very first post? There are step by step instructions there. What specifically about the instructions dont you understand?

ish

@quicksilver i typed the script module into the terminal on retropie installed it through the experimental section in the setup and installed it tried to open doom. I opened it got a black screen then it sent me back to the emulation station menu

@ish after building using the latest script I am having the same issue (on my Pi 4)

@tpo1990

Executing: DOOMWADDIR=/home/pi/RetroPie/roms/ports/doom /opt/retropie/ports/doomlegacy/bin/doomlegacy -iwad "/home/pi/RetroPie/roms/ports/doom/doom.wad"
/opt/retropie/supplementary/runcommand/runcommand.sh: line 1255: /opt/retropie/ports/doomlegacy/bin/doomlegacy: No such file or directory

After installing I am getting the above error message. I double checked and the /opt/retropie/ports/doomlegacy/bin/doomlegacy directory doesnt exist. Any idea what might be happening here?

mitu

@quicksilver Look in the install log and check if the binary was built.

ish

@quicksilver could I use the previous script if its still available some how

quicksilver

@mitu Yep doesnt look like its building correctly

"Not really" in the sense that I am correct, its not building correctly? Or "not really" its something else? :D

Im not really sure what im looking at in the log file.

Yes, it's not really building correctly.

@Solid-One I reinstalled the latest RetroPie 4.6.1 (buster) on my Raspberry Pi 3B and the older version of Doom Legacy did not include music only sound even though I did get Timidity and Freepats installed.

I then tried several times and found out that Doom Legacy does support fluidsynth, so I installed fluidsynth with apt-get and tried again with Doom Legacy. This time it worked. So apparently I am not sure if the release of Buster has anything to do with it. The only thing I can say is that it now works as it should. I have ditched Timidity and Freepats and replaced it with fluidsynth instead. It works just better.

@quicksilver What Raspberry Pi are you using and is it the latest official RetroPie?
Have you tried running the scriptmodule again to see if it will build the binary?

@mitu I noticed that the binary was not built after I replaced the older Doom Legacy 1.47.2 out with the latest version 1.48.4 and run the scriptmodule at the first time. I then tried again at running the scriptmodule and the binary was successfully built. It works on the latest official RetroPie 4.6.1 (buster) on a Raspberry Pi 3B.

ish

@tpo1990 so if I reinstall it and fluid synth it should work?

Yes if you want the previous version of the scriptmodule that is Doom Legacy 1.47.2 you can get it here:
https://raw.githubusercontent.com/tpo1990/DoomLegacy-RPI/9c6bded56e818922ae91b5fe7530e6649c7ec6a4/doomlegacy.sh

tpo1990

@ish Yes how ever if it still does not work with music ingame, then uninstall Doom Legacy and reinstall it from the scriptmodule.

For a fresh installation if you already have Doom Legacy from an previous version of the scriptmodule:

First use the existing Doom Legacy scriptmodule in RetroPie-setup to uninstall Doom Legacy.
Then use the download link from the RetroPie page to download the latest version of the scriptmodule.
Finally use RetroPie-setup and go into the experimental section to install Doom Legacy again.

If you want to make sure that there is nothing left out before reinstalling, then delete the following files and folders:
In /home/pi/RetroPie/roms/ports/ delete all the doom.sh files.
In /opt/retropie/configs/ delete the doom folder to delete config files.

ish

@tpo1990 i did what you said and it worked but the image is small and in the corner of the display

tpo1990

@ish Are you using a Raspberry Pi 4B since the image is small and in the corner of the display?

mitu

@ish If you're using a Pi4, then I guess it's normal.

@tpo1990 on the Pi4, SDL1 doesn't detect/scale the video properly. You can force SDL1 to use the dispmanx video driver for this platform - see for instance how it's done for Xrick. This should scale to fullscreen on Pi4 by default.

tpo1990

@mitu Actually I was aware about the issue with the not correctly scaled video in Doom Legacy on my Pi4 since I only tried it once, but that was not on a fresh RetroPie install and I was not sure if it was due to SDL1.

Is it this variable that will force Doom Legacy to run with dispmanx and if so how about on a Pi3B?

isPlatform "kms" && setDispmanx "$md_id" 1

ish

@tpo1990 where would I type that command in?

tpo1990

@ish You can't exactly type that as a command. It is a variable used into the building process of a binary in order to be able to run the game.
