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

For the Pi3 is not necessary, the test is done against the kms platform flag, which is not set for the Pi3.

tpo1990

@mitu Ah that clarifies it. I do remember reading somewhere that kms is used for the Pi4 platform. Thanks, I will test with dispmanx on my Raspberry Pi4 very shortly and if it works, then update the scriptmodule.

ish

@tpo1990 yay thx

@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?

It's a pi 4, I tried several times to get it to build using the latest scriptmodule but I run into the same issue each time.

Edit:
Now the build process just hangs after getting sources, might be having issues upstream.

ish

@quicksilver i used the new script on my pi 4 and it runs fine apart from the display issue

quicksilver

@ish weird, I can't get it to do anything now. Won't even start building. I'll have to keep playing with it.

quicksilver

So it looks like the problem is that I cant connect to https://liquidtelecom.dl.sourceforge.net/ im not sure what the issue is. If I try from my PC it just says it took to long to respond.

mitu

@quicksilver Re-try a few times, it's a temporary issue. If it still doesn't work, try replacing it with https://svwh.dl.sourceforge.net/project/doomlegacy/1.48.4/doomlegacy_1.48.4_source.tar.bz2.

ish

@mitu im trying to do 2 player but it recognises both key boards as player one how can I fix this

mitu

@ish I don't know, I don't have doomlegacy installed.

quicksilver

@mitu Thank you! Thant worked and the game now builds successfully now. Just forgot to add the dispmanx flag, so will have to do it again lol

quicksilver

except it seg faults with dispmanx. D'oh! :(

executing /home/pi/.doomlegacy/config.cfg

@quicksilver What happens if you start with an empty config ?

quicksilver

@mitu Didnt help unfortunately

Out of curiosity, what happens if you run it from terminal by plugging a usb keyboard and pressing F4?

You could try it and post here all the error details that appears on screen. It'll help us figure out why it isn't working on your RPi4.

quicksilver

@Solid-One It does work, just not with dispmanx scaling turned on.

Solid One

So the problem is on dispmanx, right?

Well, what about trying an approach similar to this one in SORR? AFAIK, both BennuGD and Doom Legacy were developed in SDL1, so maybe that should work (assuming that, somehow, SORR doesn't uses dispmanx).

tpo1990

From what I have tried lately on my PI4, is that it does not launch from emulationstation by its runcommand file doom.sh with dispmanx. If I change the directory to /opt/retropie/ports/doom and launch doomlegacy binary from the terminal it starts up just fine.

I'm not sure about how to solve the issue on the Pi4. Maybe someone else here could look into providing a solution. From this point it only works on older PI such as the Pi 3B.

With dispmanx?
