Vice C64 video settings

sprudel79

Hi everyone,
I am using batocera 5.24 and I have some trouble with the video settings of the vice emulator. I can access the menu with F12 and can adjust everything as needed incl. Video settings (e.g. aspect ratio or border). I can save the settings but when I start any C64 game again the video settings will be reset which is btw. not the case for other settings like joystick settings. Could anyone please tell me how to successfully save also the video settings?
Thanks in advance.

Same thing here: Before updating, it was very easy going to "Game Settings" and entering the "Per Core Settings", selecting "C64" and there selecting "Config" or "Core Provided". But since last update, no matter when I save settings and reload core, It "automagically" changes the resolution settings.

Hi everyone,
I was able to analyze the issue a bit more yesterday.
Basically Vice is using this config file here: /batocera/system/configs/vice/sdl-vicerc
There are a couple of settings included for the video settings like:
SDLGLAspectMode=0 VICIIVideoCache=1 VICIIFullscreen=1 VICIIBorderMode=3

Details about the parameters can be found here: https://vice-emu.sourceforge.io/vice_21.html
In any case, I would like to adjust the video settings globally as written in my first post above to change the border mode to Default (which means VICIIBorderMode=0) and additionally to keep the Aspect Ratio of 4:3 by setting SDLGLAspectMode=1.
When doing this and saving the file those two values ALWAYS get overwritten to the defaults. As @jackalpret already wrote, changing the settings for the C64 core won't make any difference.
Is this a bug?

By the way, I have already upgraded to 5.25.

This gets set by.
/usr/lib/python2.7/site-packages/configgen/generators/vice/viceConfig.py
that is loop mounted read only to "/overlay/base"
from some kind of img file in /boot i presume.
The short version is that if you change the values and reboot it will revert to previous values.
Still waiting for some kind of override in batocera.conf .
i saw a commit to that affect here https://github.com/batocera-linux/batocera.linux/commit/193c1825467116298b87b7bc23443b90f96523b7#diff-b04ce9391db2fb0cbd895ce435020817

That would allow us to set vice.config.VICIIBorderMode=0
but until then i think im not gonna reboot.....

Is there any chance that these configuration options will be available in 5.26?

sprudel79 it,s seems to be implemented in 5.26.

example is like c64.vice.C64.VICIIBorderMode=0 in batocera.conf for getting normal borders.

Thanks to this thread, I’ve got this working and surviving reboots now,

1) edit this file: /usr/lib/python2.7/site-packages/configgen/generators/vice/viceConfig.py
Change the VICIIBorderMode from “3” to “1”

Mine looks like this:
viceConfig.set(systemCore, “VICIIBorderMode”, “1”)

2) remount the /boot filesystem as read-write with this command
mount -o remount,rw /boot

3) run the following to make it save the changes so it will survive reboots:
batocera-save-overlay
