I'm slowly working on a Nintendo Vs. Dual System thing. The original systems could load two games at once (one on each side).
I know MAME can load both sides if it's the same game (for example supporting all 4 players in Vs. Tennis) even spreading out over two monitors. But what about two different games? Example: In the real Nintendo dual cabs you might have Vs. Goonies on one side and Vs. Super Mario Bros. on the other side.
Can MAME emulate this?
