If your screen is flipping sideways while playing (which happens by pressing B1&2 and moving Joy1), you will need to disable your PC's Intel video card's built in Hotkeys. To do so, first right-click anywhere on the desktop and go to Graphics Options>Rotation and choose 'Rotate to 0 Degrees'. Next just right-click anywhere on the desktop and go to Graphics Options>Hot Keys and choose Disable.
Cabinet Owners: If you own one of our cabinets, while in any menu/outside of a game, on your keyboard hold RCtrl (right Ctrl key on your keyboard) and press Q to get to Windows. Once you've made the change just reboot the PC. For cocktail cabinets only, you may need to set rotation to 180 Degrees.
