I have a brand new US Samurai Shodown and it's not working correctly. It boots up fine and looks great until the intro is over and the demo runs. The screen has annoying verticle lines taken out of the picture tube. This is the only game of mine that does this. From the boot up to the demo it looks flawless. I tried cleaning the cart 3 times and the connectors are so clean you could eat off of them. What is wrong here? Thanks in advance.
