well, I have problems with almost every rom. Like Micro Machines on NES glitch on character choose screen. Lethal Weapon suffers slowdowns. Basically every game is like that. Also I’ve had psx emu work super good with 2,5d games like Castlevania and now for every game the audio is stuttering rendering listening to it impossible. It was after I’ve reinstalled retropie this like broke down or something.
