okay i don't remember the exact name of it the card with the button, but it
was used as a hacking card, the button when pressed issued a NMI, so and goes
into a program on the ROM, and allows you to debug any program running at the
time, and can also save memory contents, it was used for hacking games and
removing copy protection from programs.
