I don't know why people keep talking about GFA BASIC 2.0 as if it couldn't
use the joystick.  Here's how to access the port: 

spoke &hfffc02,&h14    ; turn off mouse 
while whatever loop
  a = peek(&hfffc02)  
  print a              ; a returns the value of the joystick port.
		       ; experiment to find the exact values.

.
.
code
.
spoke &hfffc02,&h8    ; restore the mouse before exiting program.

That's it!
