Can't get Streets of Rage Remake to run properly

[g0nz0uk]

Hi,

I've had Streets of Rage Remake on my Pi2 and Pi3 over the years and I'm just built my Pi4 and I can't get Streets of Rage running full screen. It starts as a little box in the top left corner.

Here is how I installed it if others what to try:

cd ~
git clone https://github.com/zerojay/RetroPie-Extra
cd RetroPie-Extra/
./install-extras.sh

run Retropie-Setup script

Select the experimental packages and install the Streets of Rage Remake Port

pi@retropie:/opt/retropie/ports $ sudo chmod 777 sorr

After that I've downloaded the Windows version of SORR 5.1 (just Google it) and used WinSCP and copied the file SorR.dat to /opt/retropie/ports/sorr
Also copied the folders below to the same location (/opt/retropie/ports/sorr):
• manual
• mod
• palettes

Then you run the game by the PORTS selection in EmulationStation choosing the game Streets of Rage Remake.

When you run the game for the 1st time it'll ask you to choose the language (I chose English) and then the Graphic Mode Option (Chose the 1st option - NORMAL (FULL SCREEN).

Pi4

Now the game wouldn't even run on the Pi4 until I installed:

sudo apt-get install libpng12-0

All I see

I select the language then I get the graphics options that don't make much difference to the size then it might bomb out.

Any ideas?

Thanks
