Saving the Maintain Aspect Ratio setting

[TheRetroCarrot]

I'm trying to disable this setting globally or on a per game basis as I'm using super resolutions on a 240p display. I have keep aspect ratio set to 0 in the mame.ini which seems to do nothing. The maintain aspect ratio setting does not save on a per game basis, the aspect ratio is only correct if this is disabled.

Is there something I can put in the .cfg for each game, or something I'm missing to globally disable this?

Thank you.

EDIT: I got this to work on a per game basis, had my ini files in the wrong spot. Just for some reason I can't get it working globally. Not a big deal but if anyone has an idea it'd save me making a file for every single game I add.
