Contra (the first one) isn't too hard for me now (but it would be without the code) but when I was a kid it was and that's my main point, the people who played these games back then were kids, and we weren't all like that autistic kid from The Wizard who somef*ckinghow knew where the flute was in SMB3 even though he or no one else had ever played it before.
And I already explained that you get those Metroid endings depending on how fast you beat the game, if you beat it really fast you're rewarded with boobs. Sure it's just an 8/16 bit sprite of a chick in a bikini, but in 1986 it was a giant leap forward from this in pornographic achievement.
So yeah.
I'd hit it.
