Issues on new 4:3 Display

[rixs]

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)

[rixs]

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

cheers!

[trimmtrabb]

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
