i recently picked up a bobble bobble and I am having issues with the image. I took a picture so that maybe someone can help me pinpoint what the issue might be. the lines in the image are constantly moving. sometimes they are vertical and sometimes horizontal. I've never run across something like this before so I am not sure if it is a monitor adjustment issue or an issue with the board. I would appreciate any help or suggestions.

bumping this before work... hoping someone can point me in the right direction
 
It's hard to tell from the pic, but does it look like an analog moving lines (like TV interference), or something digital? I remember someone recently having a problem that looked like that from not having their video ground connected correctly (on the video wire harness), but it could also be a board problem if the lines look "digital", as in they move with game graphics.

That sounds likely. I will check all of my connections but the board is connected with a very sketchy jamma adapter. The lines don't seem like a graphics glitch but more like some kind of interference. They will sometimes move left to right and sometimes up/ down. Would be great if it is just a ground issue.
