I can confirm the bugs in KOFXI in PAL mode especially. First off, since the game has black borders in PAL mode, the lower black bar is bright blue. Second, the game is indeed horribly slow. Third, there are SERIOUS graphics corruption problems in many stages. And finally, the game shows you a black screen after the end credits, and output a "selection" sound when you press a button. After this, the Game Over screen is presented. Considering the amount of inexcusable bugs in the PAL KOFXI, I'm returning my copy back to the store. It is also inexcusable how Ignition Entertainment greenlighted such a broken port. It's as if they have never heard of quality control.
