This is a box I built to test read and write function of
the Joy Stick and Trigger. Inside the Real Dos construction set is a program
called Porttest.com that you can either light an LED or Read the port by
pressing on of the N/O push buttons. The schematic I have drawn here is for
two 9 pin connectors attached to both Joy Stick ports. For myself the one I
built is for just one joy stick port. So the drawing with the Blue background
is the one I use.
Parts for this project:

Here is what my single Joystick Port Test Box Looks Like. I also added a single pole single throw switch one leg to ground and the other leg to the trigger port.
