Don’t worry, that’s what this forum is for.
RetroArch comes pre-configured and everything will work fine. You only need to change two directories, “File Browser” which is where you save the games and “System/BIOS”, for the system files. You can also use the default folder for the bios, it’s a matter of taste.
Let’s focus on the PPA. delete the entire Appimage folder, and also delete the RetroArch configuration folder, under"HOME/.config/retroarch".
Open RetroArch and it will appear indivisible, you have to update the Assets to be able to see it well. Close it and run this in the terminal. This mini scrip installs the decompressor, download and unzip the assents in the corresponding folder.
sudo apt install p7zip-full -y; cd ~/.config/retroarch/assets/; wget https://buildbot.libretro.com/assets/frontend/assets.zip; 7z x assets.zip -y; ; rm assets.zip
At startup, it should look good.
@hunterk I installed stable to test Stable, (purge the ppa testing and delete the configuration folder). When I start RetrArch, it does not have the Assets, is this normal?
I don’t remember well, I haven’t installed it for a long time, but I think it has everything normal at startup.
