The Sega Saturn offered many great video games displaying faster frame rates than other 32-bit consoles of the time. Unfortunately, European gamers fond of the Sega Saturn have to play their games at a 17% lowered speed than gamers in the US and Japan. While manufacturers may have ignored this problem, a simple modification will enable owners of a European (PAL) Sega Saturn to run 50 Hz games at 60 Hz.
