I dug out my N64 last night for some retro fun. Almost all of the games worked fine (one needs a new battery). However, Perfect Dark does not. While playing it, the video intermittently cuts out and then comes back on. I've cleaned it thoroughly and that hasn't helped. The cutting out just leads to a blank screen (audio still works) for a second, and then back to the game. It seems to happen at regular intervals. I haven't timed it, but while trying to play, I got to the point where I knew exactly when it was going to happen.
I'm kinda lost at this point as to what could be wrong.
