Did you even read the whole read? It was already mentioned that it is simple pin9 to ground connection.

Which is the official way to create firebutton for Amigas (and C64's). Probably other machines didn't have any way to enable internal pullup which required pullups in joysticks. (same with mouse buttons, official mice don't have pullups, 3rd party Amiga/ST switchable have it)

It is fully documented in HRM and still many programmers did it incorrectly..

Result is this mess..

Simply setting one more bit in Paula IO-register would have fixed it, would have worked with both kinds of pads and joysticks...
