Section Z for the NES (Score 0)

A dumb side scroller I got when I was like 15. You can see it here. I played all the way to level 47 and then spent 4 hours and finally a pad of paper and notes to verify that the level just continually looped you around. Remember this is before the internet and cheat codes..

For some reason at the time I was fixated on 'finishing' this game since there was no save and I had been 'in the zone' to get that far and was unkillable.

Finally I just gave up and decided the programmers didn't want to finish it ;P Doing a search now it seems there was a secret exit somewhere! This would of made some sort of sense if at any other part of the game there had been any sort of tricks or hidden areas
