-- NOTES for top and using the NES controller ----------------

-- NES controller physical pin connections
        -- RED: Power (3.3 V)
        -- YELLOW: Ground
        -- BLUE: NES_controller_clk
        -- BLACK: NES_latch
        -- GREEN: NES_data

-- Remove all button ports from top and make them signals instead

-- Add ports to top:
        NES_data : in std_logic;
        NES_latch : out std_logic;
        NES_controller_clk : out std_logic;
