    Perhaps one could help me configure mame-libretro to not stretch to fit the screen. I’d like it to maintain the original aspect ratio of the games. My mame retroarch.cfg has:

    video_force_aspect = true
    video_aspect_ratio_auto = true

    I’m running with the command
    /opt/retropie/supplementary/runcommand/runcommand.sh 0 "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/mamelibretro/libretro.so --config /opt/retropie/configs/all/retroarch.cfg --appendconfig /opt/retropie/configs/mame/retroarch.cfg %ROM%" "mamelibretro"

    Edit: On closer inspection, this may be a game specific issue. I was testing with 1941, and the resolution was always stretched. Other games (Donkey Kong, Street Fighter 2, PacMan) appear to preserve aspect ratio.
