Doom Legacy - Doom Split-screen Source port

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.

ish

@tpo1990 ok

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! :(

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