Joystick on parallel port adapter: 2nd button support

Last evening I was fiddling with a joystick reading routine through the parallel port adapter.
No problem for my code, everything worked as it should.
But when I tried to read the joy/pad second button it didn't work.

I realize that there are no Amiga games that support it (until now..) but why not implement it?
According to the scheme used in PPJoy, the reading would take place on bits 12 (POUT) and 10 (~Ack):



The reading for the second button of the 'third' joystick would be trivial, for that of the 'fourth' a bit complex due to the use of F in CIA-A.
(or being tied to F makes it unusable?)

Cheers.
