hello
here is my doubt about joystick working
having the joystick port a pin for each direction, how does the processor distinguish when a player presses fire (for example) if the other player also has it pressed?
Is there an electrical diagram?
thank you
Does this help?

Select Signals (COM and COM2)
COM is the "common" pin for the Joystick 1's direction/button switches. COM2 for Joystick 2 accordingly. The COM/COM2 pins go LOW when selecting the corresponding keyboard row.
