The top side of the control panel. 1st and 2nd player start buttons; green button = coin; big black button = exit; top small black button = save game state; bottom small black button = load game state (a wonderful feature to have); blue,red,white,blue buttons = action buttons 1 2 3 and 4. I love the Groovy Game Gear 4-to-8 lever-switching joystick! And the flat metal panel is nice! Other joysticks have for screws on the top of each corner, and they tend to scrape your fingers and knuckles depending on how you rest your hands.
