  The joystick is located in first 6522 port A which address is $9111,
and the bits(0-7) you need are:
2 - joy0
3 - joy1
4 - joy2
5 - joyfire
The joy4 comes from second 6522 port B in address $9120 bit 7.
Don't ask which joyX is which direction..  Hmm, if the port A address
doesn't work try $911F since my document is seven years old and a little
bit worn..  :-(
