I played ghouls'n ghost! that was an awesome game! I would sit there for hours trying to beat it, which in the end came to nothing, because it turned off so much. I would breath a little different and the NES would decide to turn off.
My brother would walk past the NES and it would turn off...
...My sister would yell at me... and it would turn off...
I would push the power button to turn it on... and it would turn off...
...an ant in japan would move... and the NES would turn off.
