Thanks for your comments Leapinlew. The 6 buttons across the top from left to right are quarters, 1 start, 2 start, pause, tab, escape. the two clustered on the left are meant for asteroids or a left pinball flipper. The two on the right are and enter button and a right flipper button. The cluster of six buttons next to the joystick are the main focus and will accommodate Mortal combat and just about everything else. I used an I-Pac encoder and that's the fewest buttons I thought I could get away with......
I decided against a marquee purely to keep the size down and it helped accommodate the 17" lcd monitor.
I'm not sure about your monitor artwork question. Are you saying I should add something around my Bezel? I could paint a line of dots and Pac man chasing some ghosts........
