Topic: NES glitching screen

I recently bought a NES. I cleaned it and tried it. first i had the white screen but fixen that. Now it laggs and glitches a ton but csnt figure ojt what it is. Who can help me?

Could be a number of problems. Could be the contacts are worn and need replacing, could be the game itself gotta be a bit more specific.

I cleaned the game and all the connections and it still does the same think it might be a chip that is broken but dont know how i test this and whete i could buy a new one

almost forgot to say that my game had some different kind of circout board. I found 1 image on google
