Reply to joystick help

so I'm looking at joystick options to go with my midifighter when i buy it, and I found a sanwa 4/8 way joystick. now according to DJTT, we have 4D adn 4A connections, which support 4 buttons and 2 joysticks..HOW?

the sanwa joystick has 5 wires, 1 ground and 4 directions, how does one go about connecting 2 of these or am I limited to only one?

my goal was 4 more buttons, and 2 joysticks, or go with a joystick and a touchpad, no buttons


thanks y'all
