Emulation station does not recognize resolution from config.txt

[maestroni]

I have a samsung HDTV installed lengthwise in an arcade cabinet and I can’t seem to get emulation station output the 4:3 aspect ratio I set in the config.txt file. The emulators work properly when I start a game per the settings.

The forum linked below is the closest thing I have found to a solution but it looks like the file structure of retropie has changed since this post and I am unable to get it to work with their instructions.

Here is my /boot/config.txt

# uncomment if you get no picture on HDMI for a default “safe” mode
#hdmi_safe=1
display_rotate=3
# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=0

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=24
#overscan_right=24
overscan_top=50
overscan_bottom=-50
overscan_scale=1
# uncomment to force a console size. By default it will be display’s size minus
# overscan.
framebuffer_width=640
framebuffer_height=480

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

# for more options see http://elinux.org/RPi_config.txt
gpu_mem_256=128
gpu_mem_512=256
gpu_mem_1024=256

ES won’t use the framebuffer width/height values. You could try switching to a 4:3 screenmode though.

you can pass emulationstation a --resolution WIDTH HEIGHT parameter to change the render resolution which might help. you would need to edit /usr/bin/emulationstation to add the parameters or make your own launch script in /usr/local/bin

however it may not position correctly on your screen, but it’s worth a try

you may have performance issue using display_rotate btw – unfortunately es has no rotation setting of its own even though retroarch etc does.

Thanks for the reply but I don’t understand how to do either of those.

I went to /usr/bin/emulationstation and added a parameter after the line “fi”
–resolution 640 480
with no luck

then I added the following code as mentioned in the forum linked below where the user seemed to have success.
https://github.com/Aloshi/EmulationStation/issues/55

pushd “$rootdir/supplementary/EmulationStation” > /dev/null
./emulationstation -w 640 -h 480
popd > /dev/null

still no luck

Also, emulationstation does rotate and overscan per the config.txt file and seems to be running at normal speed, so at least I have that going for me.
