Ok. Here is my latest revision of the panel. I decided to go with the top fire GGG joystick with 4/8 way switching for my tron joystick. My top buttons are P1, C1, Play, Pause, Quit, C2, P2.
I love playing 2-joystick games like Robotron and SmashTV but doubt I'll have need for 2-player action of SmashTV. Should I try to fit in 4 joysticks (2 per player) on the bottom half of the panel or just stick with two? Right now the joysticks are about 21.5" apart, does that seem too far for comfortable use when playing games like Robotron?
I also decided to keep the 8-button layout for future console emulation.
Thanks for all your help!
