Hello, I try at the moment Batocera for my Raspberry Pi 3 b+. Issues with wifi solved, also threaded video helped really for smooth gameplay thanks to @Atari . But choppy / crackling audio over the 3.5 mm audio jack (from raspberry pi 3 b+) is not solved. I’m really not sure should I stay with Retropie or change to the Batocera. I like Batocera because it is easy to install and it has very good retro look on my arcade cabinet..
