Resolution switching (updated w/ confg file)

[kevlo9]

Hello.

I have been using my ArPiCADE with a HD LCD monitor (via VGA) in a Sega Astro City.

I have it moved over to a Dynamo cabinet with a Wells-Gardner D9200 arcade monitor (connected via VGA)- 600x480.

Everything loads up (menu, games, etc), but I noticed that it is switching resolutions when specific games load up. Games like NBA JAM & Mortal Kombat will load up but are off center (half of the screen is missing). I'm guessing this is due to loading up in a different resolution.

Is there a way that I can have all games boot in the same resolution and also have the menu use that specific resolution as well?

I have messed around with the config file, but nothing that I do seems to fix the issue.

This is how my CONFIG.TXT file looks...

# For more options and information see
# http://www.raspberrypi.org/documentatio ... fig-txt.md
# Some settings may impact device functionality. See link above for details

# disable Rpi rainbow splash
disable_splash=1

# Comment/uncommment to flip the image to account for monitor mounting
# this is a 180 degree flip NOT hori/vert mounting
# (see bottom of file for horizontal/vertical mount option)
#display_rotate=2

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# make sure the pi outputs to correct scanlines without overscan
# use this even when playing with overscan settings for best results
# on CRT monitors always use this setting
disable_overscan=1
overscan_scale=1

# uncomment the following to adjust overscan / picture position. Use positive
# numbers if console goes off screen, and negative if there is too much border
# also use overscan_scale so the emulators comply & still use disable_overscan
# do not adjust top and bottom or you will loose scanline perfect output although
# you can move the picture up or down evenly with okay-ish results better not to
overscan_left=33
overscan_right=32
##overscan_top=4
##overscan_bottom=-4

# ignore edid - we just want video output to do as we say anyway
hdmi_ignore_edid=0xa5000080

# force hdmi output
hdmi_force_hotplug=1

# uncomment to force a HDMI mode rather than DVI so audio works
hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
config_hdmi_boost=6

# use full spectrum RGB over HDMI
hdmi_pixel_encoding=2

## PLEASE NOTE: due to the resolution switching launcher scripts changes made

# may have unexpected behaviour (see /boot/launchers/resSwitch.sh)
hdmi_group=1
## Use only one mode at a time
# Boot and menus in 480i (rotated games in 480i, non rotated games in 240p/256p/288p)

# Extra settings for ARpiCADE do not unhash these settings to use them

Any help is greatly appreciated.

sorry for the slow reply, I missed this post. We've all moved to arpicade.net please come and join us there.

Long story short your config.txt looks right to do purely 640x480p but what actually happens during opperationj varies a bit depending on which version of ARpiCADE you're using and you didn't specify...

High res mode should behave the way you hoped though with the res switching disabled and all games and menus in 480p. Not sure why it isn't working for you, could be a particular emulators settings or launcher needs tweaking.
