Need help getting SORR to run on pi 4

[quicksilver]

Im trying to setup streets of rage remake on my pi 4. Im using the build script found in the zerojay retropie extra repository which has a lot of build scripts for games that for one reason or another are not included by default in vanilla retropi. (https://github.com/zerojay/RetroPie-Extra)

This is the build script for sorr (works fine on my pi 3)

#!/usr/bin/env bash

rp_module_id="sorr"
rp_module_desc="Streets of Rage Remake"
rp_module_help="Please copy your SorR.dat file along with the mod and palettes folders into $md_inst."
rp_module_section="exp"
rp_module_flags="!x86 !x11 !mali"

function depends_sorr() {
    getDepends libsdl-mixer1.2
}

function sources_sorr() {
    gitPullOrClone "$md_build" https://github.com/zerojay/bennugd.git
}

function install_sorr() {
    md_ret_files=(
    'bgdi-330'
    )
}

function configure_sorr() {
    mkRomDir "ports"
    chmod 755 "$md_inst/bgdi-330"
    moveConfigFile "$md_inst/savegame" "$md_conf_root/$md_id/"
    addPort "$md_id" "sorr" "Streets of Rage Remake" "pushd $md_inst; ./bgdi-330 ./SorR.dat; popd"
}

However once I run the game, it crashes back to ES. The runcommand log shows that it cant locate a dependency:

Parameters: 
Executing: pushd /opt/retropie/ports/sorr; ./bgdi-330 ./SorR.dat; popd
/opt/retropie/ports/sorr ~
./bgdi-330: error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory
~

Im thinking that this dependency must not longer be available on raspbian buster or they moved onto a new version of libpng. Can anyone help me figure this out? Many thanks in advance.

v12 has been replaced with v16.

$ sudo find / -type l -name libpng[12,16]*
/lib/arm-linux-gnueabihf/libpng12.so.0
find: ‘/run/user/1000/gvfs’: Permission denied
/usr/lib/arm-linux-gnueabihf/libpng16.so
/usr/lib/arm-linux-gnueabihf/libpng16.so.16

You can see the symlink for libpng12 is under /lib/ not /usr/lib/.

@rejesterd Thanks, is there a way to change the symlink to point to the correct directory?

[rejesterd]

You can try making a new one..

sudo ln -s /lib/arm-linux-gnueabihf/libpng12.so.0.54.0 /usr/lib/arm-linux-gnueabihf/libpng12.so.0

Make sure the above file is actually there under /lib/... before making the link. I had 12.0.54.0 installed already, but yours could possibly be slightly different.

[quicksilver]

@rejesterd I dont have a libpng12.so in my /lib/ folder

[rejesterd]

To install it, run..

sudo apt-get install libpng12-0

Then check again. And maybe try running sorr before adding the symlink.. you might not need it after installing the package. I did try getting it to work on my pi4, but I get a different error when launching (I assume I have the wrong .dat file or something else is missing).

Thanks for this. I managed to install and run SORR on a pi 4. However, the image is not resized to fullscreen, it is just at the upper left corner and just fills 1/4 of the screen. I've tried with the different video options (fullscreen, 2x, scalines, etc.) with the same result. The same config produced a fullscreen image on a pi 3. Any clues?

[quicksilver]

@janderclander14 unfortunately, from what I understand any game that relies on sdl1 won't scale through runcommand on the pi 4. Ive tested sorr on my pi 4 as well and can confirm the behavior you are seeing. I don't know what/if there is a solution.

@mitu would there be a way to use dispmanx here to get the game fullscreen? I know dispmanx seems to stretch the image to fullscreen with dosbox.

[mitu]

@quicksilver dispmanx might work. You need to add dispmanx to the rp_module_flags, and then use Configuration/Tools menu to enable it for the port/emulator, so it can be toggled by runcommand automatically.

[quicksilver]

@mitu So I added dispanx to the rp_module_flags and enabled it for sorr. However the game wont launch successfully now. The runcommand.log shows this error:

Parameters: 
Executing: SDL1_VIDEODRIVER=dispmanx pushd /opt/retropie/ports/sorr; ./bgdi-330 ./SorR.dat; popd
/opt/retropie/ports/sorr ~
./SorR.dat: doesn't exist or isn't version 7 DCB compatible
~

I am assuming that it has something to do with the pushd/popd commands but im not sure how to modify it since Im not entirely sure what pushd and popd do (or if thats even the issue).

[mitu]

@quicksilver said in Need help getting SORR to run on pi 4:

Executing: SDL1_VIDEODRIVER=dispmanx pushd /opt/retropie/ports/sorr; ./bgdi-330 ./SorR.dat; popd

Try modifying the emulator command to

pushd /opt/retropie/ports/sorr; SDL1_VIDEODRIVER=dispmanx  ./bgdi-330 ./SorR.dat; popd

and remove my previous suggested configuration.

[quicksilver]

@mitu

Parameters: 
Executing: pushd /opt/retropie/ports/sorr; SDL1_VIDEODRIVER=dispmanx  ./bgdi-330 ./SorR.dat; popd
/opt/retropie/ports/sorr ~
./SorR.dat: doesn't exist or isn't version 7 DCB compatible

same issue unfortunately

[mitu]

@quicksilver Do you have the SorR.dat file in /opt/retropie/ports/sorr ?

[quicksilver]

@mitu It was there...until I reinstalled with the dispanx flag set...sorry about that.

So i added it back to the sorr directory and I can now get the game to launch using your original instructions. However the window is still just small in the upper left corner of the screen. :(
