wolf4sdl black screen on launch, audio playing keyboard working

kaltertod

running the latest release of retropie on a rpi4 running stock clocks. I launch wolf4sdl from the ports menu in emulation station and I get a black screen with the audio playing in the background. keyboard works, I can press ESC and exit from the game just fine.

the game launches correctly but I am not getting any video output. however if I navigate using the keyboard to exit the port jumps back to emulation station no problem. The log shows no errors.

anyone have any ideas?

@kaltertod please be more specific with details. Latest version isn't enough info.

Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first

Also check dispmanx settings for wolf4sdl in RetroPie-Setup /
-> configuration / tools)

Should be enabled for RPI4

kaltertod

Dispmanx is enabled for wolf4sdl it is also kind of funny I cannot disable it either, runcommand.log shows no errors upon launch of the game... still have a black screen if you can point me to a log file that will give some information I will be happy to post it.

I have uninstalled and removed all game files from the /roms/ports/wolf3d directory, removed the /roms/ports/wolf3d directory and done a full reinstall of the the port and will see if this makes a difference.

@kaltertod the log shows no errors or is empty?The log may still be useful to reproduce the issue.

If you still have the issue please post a log and also the contents of /boot/config.txt

@kaltertod You've disabled the Pi4 fkms overlay and you're using the KMS only GPU driver. This is not a standard RetroPie config and that's why the game doesn't work - dispmanx is not available for your system.

cyperghost

@kaltertod Did you try ecwolf instead?
I made best experience with this mod therefore I wrote the script installer, sadly it wasn't accepted.
Main Thread is here - but consider also that what @mitu told you. As long you are not using a standard version it's hard to help.

kaltertod

I will try and go back to fkms and see what happens oddly it worked before....... and I will give ecwolf a shot

kaltertod

Disabled full kms driver and went back to fkms still no dice.... however, I uninstalled wolf4sdl and installed ecwolf and it now works flawlessly. Thanks Ghost I will mark this solved for now.
