Mame4all aspect ratio

[stathman]

Hi,

i’m using a 1920×1200 monitor and i can’t figure out how to force aspect ratio
when using mame4all.

Therefore most of the games are displayed stretched.
When i use libretro the retroarch.cfg does the trick but i would like to use mame4all instead.

Is there any way of forcing aspect ratio in mame4all?

Thanks

I’d like to know also :) It’s probably really simple.

Is my question too stupid or it is hard to answer? :)

right after loading a rom if you press X on your keyboard or I think you can hold down any key on your keyboard, it will bring up a menu that you can select what resolution you want to run that rom in. You could do this for each game.

Hi,
i have tried all the available resolutions
but there is no difference.

I think whatever i select, nothing changes.

When i make a choice
at the bottom of the screen a line appears with the message:

/opt/retropie/lib/inifuncs.sh: line 60
/op/retropie/configs/all/videomodes.cfg: Permission denied

When the emulator is set to lr-imame4all
i can change the resolution successfully.
