      Hey guys

      I'm running emulation station/retroarch (Colton downs vertical revision) and I'm trying to output through the gert vga666 in 640x480 in 31khz to an arcade monitor and I was just wondering which values would be required? I'll post my config shortly, but any help would be greatly appreciated

      BTW disable SPI and IC2

      heres my config

       # For more options and information see
       # http://rpf.io/configtxt
       # Some settings may impact device functionality. See link above for details
      
       # uncomment if you get no picture on HDMI for a default "safe" mode
       #hdmi_safe=1
      
       # uncomment this if your display has a black border of unused pixels visible
       # and your display can output without overscan
       disable_overscan=1
      
       # uncomment the following to adjust overscan. Use positive numbers if console
       # goes off screen, and negative if there is too much border
       #overscan_left=16
       #overscan_right=16
       #overscan_top=16
       #overscan_bottom=16
      
       # uncomment to force a console size. By default it will be display's size minus
       # overscan.
       #framebuffer_width=1280
       #framebuffer_height=720
      
       # 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)
       #config_hdmi_boost=6
       #hdmi_ignore_edid=0xa5000080
       #hdmi_group=2
       #hdmi_mode=4
      
       #this was added to force vga note 640x480 60hz
       dtoverlay=vga666
       enable_dpi_lcd=1
       display_default_lcd=1
      
       dpi_group=2
       dpi_mode=4
      
       # 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
      
       #uncomment to overclock the arm. 700 MHz is the default.
       #arm_freq=800
      
       # Uncomment some or all of these to enable the optional hardware interfaces
       dtparam=i2c_arm=off
       #dtparam=i2s=on
       dtparam=spi=off
      
       # Uncomment this to enable the lirc-rpi module
       #dtoverlay=lirc-rpi
      
       # Additional overlays and parameters are documented /boot/overlays/README
      
       # Enable audio (loads snd_bcm2835)
       dtparam=audio=on
       gpu_mem_256=128
       gpu_mem_512=256
       gpu_mem_1024=256
       overscan_scale=1
      
       # Pretends no audio formats are supported by HDMI display, forcing all sound out the 3.5mm headphone jack.
       # May not be needed for all HDMI devices
       #this was turned on to enable the 3.5 audio jack
       hdmi_ignore_edid_audio=1

        You don't seem to run RetroPie, so why post here in the forums ? You can find the list of resolutions you can add in config.txt here.
