I have three games for my Jaguar, Raiden, Cybermorph and AvP. While Raiden and Cybermorph play fine with no flickering AvP flickers during gameplay. I'm hooked using an official RF connector. I've cleaned the cart and the contacts on the Jag but it continues to flicker only during gameplay. The menu screen is fines and audio is always clear. I'm going to buy an AV cable for it soon but I'm hoping this problem doesn't persist with the AV cable as well. What would cause this flickering only with AvP?
