An all-in-one solution for optimizing your gaming experience. This unique device eradicates the complexity of configuring the spinner and trackball in RetroPie by merging these functions into a single unit. Traditionally, the separate USB mouse peripherals of a spinner and trackball required manual configuration for each input, further complicating in-game mapping. But with our TS-SPTB-COMBO, these hassles are things of the past. This combo unit is built on our proprietary optical technology and delivers exceptional trackball performance. It integrates spinner and trackball functions into one USB mouse output, greatly simplifying MAME configuration and ensuring wide compatibility across various systems. The GRS LED Trackball with Spinner is not just about function; its also about style. With customizable LED effects, it adds visual appeal to your gaming setup. The spinner is designed for a 28mm hole mounting setup, making it a perfect fit for DIY projects, arcade modifications, and more.
