I am running AtomicFE and MAME32 on a two-sided cocktail cabinet.  I am having difficulty setting the AtomicFE Manager so that it will play horizontal games vertically (i.e., allow me to play horizontal games on a cocktail cab).  Is it possible to play horizontal games vertically?  I know I can play vertical games horizontally but wasn't sure if I could do the opposite.  
Thanks in advance to anyone's help -- I've been spending hours trying to get the settings to work to no avail.
