Ideal input device for Arkanoid and Marble Madness
There are real Trackballs to buy like "Ultimarc U-Trak" or "X-Arcade Trackball Assembly" or completely assembled: "X-Arcade Tankstick + Trackball" (= https://shop.xgaming.com/products/x-arcade-tankstick-trackball-usb-included )
Not cheap, but near to the "real thing"
