I have my RPi up and running with RetroPie and ES. My NES games work with no issues but my other emulators…Ports, MAME, etc files kick me back to ES when trying to load them. Can someone list what file types for each emulator I need? Anyone know why Duke Nukem would kick me back into ES without loading? I figure I am doing someone wrong when I am copying the files into each respective folder. i.e. Do I need zip files for MAME? Any help would be appreciated….thanks!
