When I play Samurai Spirits 4 and Real Bout Fatal Fury with my 4meg cart, my opponent will sometimes turn into a large, single colored, pixiliated mess. Anyone hard of this problem or a remedy? I've never had this problem with Metal Slug, another 1meg SNK game or any of the Capcom games. I can't test if its the 4meg cart, but I have 2 and they both do it. I do not have a 1meg cart.
