managed to resolve myself.
Apparently these are just warning messages and are only preventing successful compilation because of the -Werror flag in the makefile. Removed that flag and it now compiles successfully
After my genius idea to delete all stuff in this discussion, which only cause trouble and chaos, I figured out to do another attempt and post again. This is version 2 of the little app. The gui and commandline are streamlined into one app. The commandline options are flexible now and it supports a configuration file. Unfortunately in GUI mode only one patch file at a time is supported (but I think this is not a real issue and is a limitation in GUI only). And it can create output folders too. Updated the first post with all relevant information.
@mitu I was running a normal XOrg session before (which is the default on PopOS), but running emulationstation in a Wayland session worked! Unfortunately, Wayland is pretty unstable in PopOS, but maybe it will work just for running retropie.
In case anyone runs into the same issue, you have to enable Wayland as described here and it will work.
I think Ubuntu wouldn't allow it since it was a 'hidden' folder.
First time I hear this kind of - obviously wrong - explanation. Check the permissions on the folder and make sure your $USER owns the folder where the scripts are saved. You don't need to use sudo to edit something that's in your home folder.
Could also been something I mucked up; since I installed using net-inst, I checked the permissions and they looked fine.
Does updating RetroPie works ? If yes, then you're connected to the internet. You also have a 'Show IP' entry in the RetroPie system in Emulationstation that can show you if you are connected to a network (LAN).

@mitu Is solved now if I changed the theme and worked everything. I just have in some psx games issues with te control but is minimal. Thank you for all. Now is time to play after the hard work of configuration almost 3 weeks wow!
Ok I will try but also check one photo and it says also, besides that, Audio Manager error ALSA, something like that, SDL audio problems. With that fbset can be fixed also?
@cyperghost Thank you dormthe help. It was very useful. Thanks to your comment regarding “odroid-config“, I found that it existed but now is integrated in the Odroid utility and that you can call if works for reference to other lost soul:
