I suppose I should also embarrassingly confess that the only NES-native game I've beaten was Super Mario Bros. 3, and that was via the GBA version. Uh oh. Also Mega Man 2 will be the first non-Mario 2D platformer I will hopefully finish.
I still think I'll be keeping passwords, if only to be on the safe side.
