Felix vs Jerry (AKA Felix the Cat 2) is a hack of Tiny Toon Adventures released sometime in 1995. The game features characters from various cartoons.
Like most hacks, only the graphics are changed, while the original levels, music, colors and text are retained. The four original characters (Buster, Plucky, Dizzy Devil and Furrball) were replaced with Felix, Woodstock, and two seemingly original characters, respectively, and the generic mouse enemy is now Jerry. Montana Max, Babs and the shark are shown to be replaced by Jerry, Kitty and Jabberjaw in the intro, although they remain intact in the actual game. The bird in the end of level cutscene has also been given a Mickey Mouse hat. The strangest change is the game over screen, which features the mouse from the original game being chased by an angry Sylvester.
