Recently, I bought a Ms. Pac-Man Coleco Tabletop game from a garage sale (and for only $10!) I put new batteries in and it worked great. But the next morning, I turned it on and chose 1 player game, however it started the 2 player game. Also, moving the joystick down during gameplay will make you move one frame to the left, the same thing happens when you press move it left (for both players). Moving it up and right will move you normally in those directions. If anyone knows what could be causing this strange problem and tell how to fix it, that would be great.
