I like your graphics aswell.
I really don't like a big cluttered cp with controls for every game ever made on my machine cp, i would narrow your cp and controls down to games you really want to play and get rid of every controler. I'm not a big fan of having all you can squeeze on there like most do. (real arcade cabs do not look like that)
It's really up to you but i thought i would give my opinion.
Goodluck.
