I play my mame games with the auto rotate option on, so the vertical games come up vertical on the monitor and the horizontal games come up horizontal. Of course I must rotate and degaus my monitor each time I change the orientation. What I really hate though is when I play a vertical game e.g. Galaga and decide to change to another game the menu is still horizontally orientated, which means either rotating my monitor (or usually my head) to navigate through the menu to pick another game which may be a vertical game and have to rotate it back.
Is there a front end out there that automatically senses the orientation of the last rom selected and is able to change the orientation of the menu to suit the way the monitor is currently positioned?

I haven't heard of such a front end but like most things to do with mame that I think of, I usually find someone else has thought of it first.
If there isn't a front end out there that does this already, is there any chance of anyone adding an option to there front end to do this?
I'm thinking Mamewah, Dragon King, Emulaxian etc.
