Problem in Raspberry pi 4?

[jajalobrit]

Is this fork compatible with raspberry pi 4?
I already use it on raspberry pi 3 but now trying on a raspberry pi 4 (using the same version of retropie) after compiling when trying to run the emulationstation I get this in terminal :

"failed to export dumb buffer: Permission denied
Failed to create scanout resource

• failed to add service - already in use?"

Any idea what it might be?

This fork hasn't been updated for more than a year so it's probably not compatible with pi4. No idea what these error messages mean though.
