changing resolution of Retroarch menu

[danfun]

I need to change resolution of the Retroarch menus, including the in game menu. I am using Retropie on a CRT and the menus are stretched and don't fit. I have a custom resolution set at 1600x240 so that games can scale accordingly to that with integer mode. So must be that my menus are stuck at width 1600 also... How do I change this?

@danfun

I have a custom resolution set at 1600x240

Isn't that 240p?

If so, then edit /boot/config.txt

# Force the monitor to HDMI mode so that sound will be sent over HDMI cable
hdmi_drive=2
# Use HDMI mode even if no HDMI monitor is detected
hdmi_force_hotplug=1
# HDMI type CEA
hdmi_group=1
# 240p @ 60 Hz
hdmi_mode=8

Scratch what I said above and read this thread:

I could not find the solution in that thread what I could see...

woops sorry, posted the wrong reply in that thread:

@arkive is editing /boot/config.txt and uncommenting these 2 separate lines:

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
disable_overscan=1

# Enable audio (loads snd_bcm2835)
dtparam=audio=on

...and then adding:

disable_audio_dither=1
dtoverlay=vga666
enable_dpi_lcd=1
display_default_lcd=1
dpi_group=2
dpi_mode=87
hdmi_timings=320 1 16 30 34 240 1 2 3 22 0 0 0 60 0 6400000 1

or

hdmi_timings=256 1 8 17 21 224 1 7 10 24 0 0 0 60 0 4800000 1

I'm not 100% sure about the hdmi_timings= because it would have to be what ever your CRT is actually using. I've been kind of looking around to see if I can find more information about that.
