please help

Have you tried a different TV set?  That "runs up and down" stuff kind of sounds like what you'd get if your vertical hold was screwed up...

Do you mean that the game glitches up, or the picture rolls up, or what?

Although, the fact that you can play it in either position kind of makes me think that your lockout chip might be messed up, as noted above.  Or, more likely, the little "lockout chip defeater" inside the cart might not be working.  Try a toploader.
