Hi i just recently picked up a atari 7800 from ebay the seller listed it as working but he said there was problem with controller port1 when you turn on the console and play astroids the ship continues turn around. I allso got ikari warriors when i put this game on player1 goes to the left all the time but player2/controllerport2 works great.Two caps were bulgeing one at the front and one next to the cartridge slot.I have replacent these and still the same.I think it could be controller port1 can any help me please:-(
