In
this post, Deksar asked about the possibility of resetting the PowerPak back to the menu based on button presses. How feasible would this be? A custom mapper would have to at least snoop $4016 and $4017 accesses to see what buttons are being pressed.
Is this all that different from how TheFox's save-state powermappers works?
Yeah, my mappers (both the old Save State Mappers and the newer PowerMappers) do it by spying on the $4016 accesses that the game makes (can't remember if it does $4017, probably not).
