    On this topic including RetroPie. I am using 3.5″ PiTFT (Pi 2 & previous working edition on RetroPie)

    I would like to fill the whole 3.5″ LCD, currently it has black bars on right/left side. I know the only way might stretch the pixels.

    Trying to figure out what config file controls games(mame) on LCD. The RetroPie front end menu system fits nicely full screen.

    Change aspect_ratio_index in /opt/retropie/configs/all/retroarch.cfg to force to the aspect of your screen.

    for my dev monitor (5:4) that would be aspect_ratio_index = “10”

    you can count from 0 in the retroarch gui settings to work out the value without having to save the entire retroarch.cfg or can configure from there / save new config and extract the value needed.

    ASPECT_RATIO_4_3 = 0,
    ASPECT_RATIO_16_9,
    ASPECT_RATIO_16_10,
    ASPECT_RATIO_16_15,
    ASPECT_RATIO_1_1,
    ASPECT_RATIO_2_1,
    ASPECT_RATIO_3_2,
    ASPECT_RATIO_3_4,
    ASPECT_RATIO_4_1,
    ASPECT_RATIO_4_4,
    ASPECT_RATIO_5_4,
    ASPECT_RATIO_6_5,

    ASPECT_RATIO_8_3,
    ASPECT_RATIO_8_7,
    ASPECT_RATIO_19_12,

    ASPECT_RATIO_32_9,
    ASPECT_RATIO_CONFIG,
    ASPECT_RATIO_SQUARE,
    ASPECT_RATIO_CORE,
    ASPECT_RATIO_CUSTOM,

    16:9 is aspect_ratio_index = 1

    No need to post the full config here – makes threads hard to follow – please use pastebin or similar.

    if you are talking about the default mame4all, or advmame – neither are retroarch emulators so they dont use this config. I think mame4all-pi might need a patch to “fit to screen”.

    Thanks for the help.

    Where do you see mame4all-pi ?
    Im not seeing that.

    Were you referring to the whole package in general Mame4all-pi and not a config file?

    Thanks
