After doing a little research it seems that you can configure MAME to rotate the vertical games in their proper format using command lines. There is however another version of MAME specifically designed for Windows....MAMEUI. This operates like your typical Windows program. It also acts like a front end. This probably wouldn't be practical when using Launchbox. Since Launchbox can work on a portrait oriented monitor,I'm going try and configure MAME using command lines. This should enable me to play games like Donkey Kong,Pacman,Centipede ,etc in their original format. I guess I'm a purist when it comes to playing my favorite arcade classics.
