Help with a game name that I forgot...

[Pac-man]

hmm...i would remember but i was about 5.8 years later and i forgot most of my memorys.XD

i know that it was a side scroller.
there was 2 players co-op
was not a space shooter.
i think there was a red guy and a blue guy.1st and 2nd player.
when you die you respawn immediatly.i think.
and you jump ledges to proceed.not many but yeah.

any help?

Were you referring to Contra (which I think is called Probotector in Europe)? http://www.nesguide.com/games/contra/
Or perhaps its sequel, Super C (called Probotector II in Europe)? http://www.nesguide.com/games/superc/
