    Hey Guys,

    im working on this problem since Days and i have no idea how to fix it.

    Everything is working just fine on my 16:9 Display. Ive build an arcade Controller which also works perfectly.

    Now i want to build a little Desktop arcade cabinet with a 17″ 4:3 Display.

    All of the sudden the screen goes black (like it lost input) when i load snes games. I only encounter this issue with snes games.
    its connectet via HDMI to DVI.

    thanks for this Forum (helped me a lot)

    Cheers,

    Rixs

    what hdmi_mode are you running on?

    power off the Pi, take out the memory card and load it on your computer.
    find the config.txt and locate the hdmi_mode setting and find one that works for your monitor?

    thanks for the quick answer proxcell.

    i tried various hdmi_modes

    As i said, the monitor works fine until i load up a snes game.
    Then it immediatly turns black.

    cheers

    it seems like the 4:3 games are working correctly, only if a game is in 16:9 ratio, the screen turns black.

    atm output is on auto detect. if is set the correct hdmi_group=2 and hdmi_mode=16 for the monitor, NOTHING is showing up.
    on auto detect it works fine until i load a snes 16:9 game.

    any ideas?

    cheers

    What display resolutions does the monitor support? And are you using pisnes or the retroarch/libretro core (check es_systems.cfg)

    Hey trimmtrabb,

    the native resolutions is 1280×1024 which is hdmi_mode=35. This doesnt do the trick though.

    es_systems.cfg says:

    <system>
    <fullname>Super Nintendo</fullname>
    <name>snes</name>
    <path>~/RetroPie/roms/snes</path>
    <extension>.smc .sfc .fig .swc .SMC .SFC .FIG .SWC</extension>
    <command>/opt/retropie/supplementary/runcommand/runcommand.sh 4 “/opt/r$
    <!– alternatively: <command>/opt/retropie/emulators/snes9x-rpi/snes9x $
    <!– alternatively: <command>/opt/retropie/emulators/pisnes/snes9x %ROM$
    <platform>snes</platform>
    <theme>snes</theme>
    </system>

    Try changing runcommand.sh 4 to runcommand.sh 2 in the SNES section of es_systems.cfg (reboot for changes to take effect)

    You sir, are awesome. it works now, thanks a lot!
    Could you explain what the change on runcommand did though?

    cheers!

    Glad you sorted it 🙂 The runcommand script changes the resolution when an emulator is started, more info here: https://github.com/retropie/RetroPie-Setup/blob/master/supplementary/runcommand.sh
