in my case i built a lakka machine on a Pi4 but just the first rom i tried is unplayable. The sounds cracks and the core take to much cpu power i guess.
I had a retropie on that Pi before and the sound was good and the game was running smooth.
Where can i find and whats the last version of lakka with the delete/add cores option?
Edit: retropie is not an option to me, i just want rotroarch on my system.
