I posted a file with a slightly better version of the control panel. There are several variations of this panel with different graphics and colored trackballs but this is what I went with.
I also updated the player buttons on Super Breakout (still looking for a better scan of the marquee). Still trying to decide what to do with the spinner knob as the movement on a black one didn't show up very visibly on Tempest.
