Digimon Pendulum X VER. 1.0 Released in 2003 Over 20 years old. Although it's faded overall, I've briefly checked the screen and operation, and it seems to be working fine. A new concept handheld device that adds the dice probability function "XAI (Sai) System" to the Digimon Pendulum. Available in two colors: Dark Blue & Orange and Black & Red.
