Well, I'm stuck... I'm trying to work with a rotating monitor, that I can change from 4:3 to 3:4 for playing horizontal/vertical games.
I've done a fair amount of Googling, reading the (sparse) documentation of Advmenu and Advmame, and can't figure it out. Anybody have some suggestions?
I want to load say Centipede, and rotate the monitor vertical, and rotate the game vertical. Then switch to say Moon Patrol and rotate the game and monitor horizontal. I'm not concerned right now with automating the physical monitor orientation, but want to figure out how to change the orientation of the game itself, either when advmenu calls the game, or when advmame runs it.
