Have you tried taking it to an italian resturant, have a couple bottles of wine till 2am...then having great conversation with it as you drive it home, saying things like "We really get each other"?
From there give it a good night kiss, it should ask you to come in for a nightcap.
Usually at that point, I ask if it wants to watch a movie and then work up to it closer and closer until I'm throwing my tongue in it...
Then I slowly rub it's expansion slot until it rolls to the floor where I gently lick around the hinges of the enclosure while telling it, that it tastes so good... Some times I throw a finger in there while biting the "power" and "reset" button slightly. Then usually I'll nibble its power cord a bit until I look it in the blinking red light and thrust the grey cartridge into its gaping orifice. If you press it down, at the right spot... you're golden.
Then its on to some Mega Man 2! Hell yeah!
Anyways, thats what usually works for me, just keep at it... and it'll moan in Mario 3 everytime.
*Dont know if this works on a Famicom, I'm not into asians.
