Bezel artwork - aspect ratio issue

[T4-calo]

When loading any 4:3 Mame games, by default the artwork bezel looks fine but the Mame game loads in 16:9. The only way to make the game look right is to change the video settings in the game to 4:3, which removes the artwork bezel.

How can the games be launched so the aspect ratio is correct while also keeping the bezel artwork?

Can you post a screen shot of a game with it's bezel active, as well as the game's lay file content?
