Yes I am talking about the horizontal images (as most NES/SNES games were horizontal).
It would be fall down the feature list of some of those emulator makers, I admit. Just wondering if anyone had figured it out. I am excited about making a cocktail machine, and some of those Nintendo games would be fantastic with a friend across the table from me. Luckily some of the best games have better versions on Mame (like TMNT2, NBA Jam, Street Fighter 2, etc.), so those will be fun and easy with the Mame Cocktail mode.
