It seems in the original NES version of Kirby's Adventure, turning off the console results in you losing all progress into the "extra" game where you play again with only 3 health (and 2 lives). On Wii Virtual Console, you could use the "save state"-ish feature to just never turn off the game. However any time the game resets would cause you to lose the "Extra Game" and forcing you to start over start all over.
Is this still the case in the 3DS version? Since there doesn't seem to be any way to "save state" like on Wii version, would I lose the "Extra Game" if I switch to another game or restart/turn-off the 3DS?
